they produce different By-products such as water, ammonia, and HCl, etc. In addition polymerization, the entire monomer molecule becomes a part of the polymer. There are many differences between the two processes. Condensation polymerization, on the other hand, forms polymers through the process of condensation. Further, it is important to note that addition polymers can be formed through chain polymerization. The polymerization process takes place in three distinct steps: 1. Polyester and nylon are some of the most common examples of this type. We will also discuss some questions related to addition and condensation polymers in the Frequently Asked Questions (FAQ) section later. the repeated addition of monomers having double or triple bonds of polymers is called Addition polymerization. The distinction between "addition polymerization" and "condensation polymerization" was introduced by Wallace Carothers in 1929, and refers to the type of products, respectively: a polymer only (addition) a polymer and a molecule with a low molecular weight (condensation) There are a few ways that monomers combine to form the polymers of plastics. Monomers should either have a double or triple bond, Monomers must have either two similar or different functional groups, No by-products are produced in this reaction, By-products are produced in this process. On the other hand, condensation polymerization is a process that involves the repeated condensation reactions between tri-functional or bi-functional monomers. Mention the reaction that is accompanied by the removal of by-products during the formation of polymers. An addition polymer is a polymer that forms by simple linking of monomers without the co-generation of other products. on the basis of different reactions, Polymerization is divided into two major types i.e, Addition polymerization and Condensation Polymerization. In this article, we are going to discuss condensation type of polymerization. The other important and alternative forms of polymerization are polyaddition and chain polymerization. Some examples of common condensation polymers are polyacetals, proteins, and polyamides. In addition polymerization (sometimes called chain-growth polymerization), a chain reaction adds new monomer units to the growing polymer molecule one at a time through double or triple bonds in the monomer. Pro Lite, CBSE Previous Year Question Paper for Class 10, CBSE Previous Year Question Paper for Class 12. The key difference between addition and radical polymerization is that the addition polymerization occurs via the addition of unsaturated monomers whereas the radical polymerization occurs via the addition of free radicals.. Polymerization is the process of producing a polymer using a large number of monomers. It is also important to note that, usually, almost all polymers are unsaturated compounds - some examples of this include alkalines and alkenes. 3. The difference between addition and condensation polymerization is that for addition polymerization, monomer should be an unsaturated molecule whereas for condensation polymerization, monomers are saturated molecules. Fun Facts about Addition Polymerization and Condensation Polymerization, Difference Between Evaporation and Distillation, Difference Between Herbicides and Pesticides, Difference Between Isomers and Allotropes, Vedantu Based on this kind of reaction, one can state that polymerization is divided into two groups. Monomers are small molecules that act as building blocks of polymers. When we keep adding monomers to obtain a large chain, such a process is also called as the chain growth polymerization. However, the difference exists in the fact that this process generates various other products. This process is done in three steps. Step growth polymerization is also known as condensation polymerization. These three steps are the initiation of free radical, chain propagation, and termination of the chain. while the repeated process of condensation reactions of two different bi-functional or tri-functional monomers is said to be Condensation polymerization. The addition polymerization definition is that this is the process of repeated addition of monomers. The main difference between addition and condensation polymerization is that in addition polymerization the polymers are formed by the addition of monomers with no by-products whereas in condensation polymerization, the polymers are formed due to the condensation more than one different monomers resulting in the formation of small molecules such as HCl, water, ammonia, etc., as by-products. So, the next obvious step is to discuss the difference between addition polymerization and condensation polymerization. This is done when the polymer is formed by sequentially adding different monomer units to an active site of chain reaction. This means that linear polymers are produced from bifunctional monomers, which refers to compounds with two reactive end groups. This is almost everything that students need to know about addition and condensation polymers. in condensation polymerization, Lewis acids or bases, also used as catalysts. Examples of addition polymerization:  PVC, Teflon, polyethylene,  etc. 3. Till now, we have looked at the difference between addition polymer and condensation polymer and the meaning of addition and condensation polymerization. This means that the peptide or ester bonds between the monomers can be hydrolyzed. The most commonly lost molecules in this reaction are water and methanol. Pro Lite, Vedantu The molecular weight of the resultant polymer is not a multiple of the monomer’s molecular weight. these monomers contain two functional groups, Your email address will not be published. These two groups are addition polymerization and condensation polymerization. polymerization is a process or phenomenon in which a large number of small molecules are combined to form a big or macromolecule. … The process of addition polymerization also mainly takes place through the process of free radical mechanism. Did you know that addition polymers are usually chemically inert? in this process, a large number of molecules take part and many monomers are combined to form large molecules. 4.Describe biopolymer and synthetic polymer. Both of these processes can also be used to get addition polymers. Polyesters Condensation polymers are formed when two different monomers are linked together with the removal of a small molecule, usually water. Addition polymerisation is the name given to a chemical reaction in which unsaturated monomers are joined, forming a polymer. Answer: In truth, the chain growth process is usually much slower than the addition reaction. 2. Polymers are giant molecules formed when smaller molecules, known as monomers, link together during the chemical reaction known as polymerisation. The remaining 22 chapters are concerned with new and better polymers designed for a specific end use or physical property. Addition polymerisation: Monomer must have at least a double or triple bond.Condensation polymerisation: Monomer must have at least two similar or different functional groups. WJEC Chemistry. Condensation polymerization definition is - polymerization in which a single molecule is eliminated —distinguished from addition polymerization. There are two types of polymerisation reactions, addition and condensation. There are integral steps and products used in this process. These two groups are addition polymerization and condensation polymerization. Addition polymerization differs from condensation polymerization, which does co-generate a product, usually water. We will also look at some questions related to this topic. 4. Your email address will not be published. 3.What is interfacial polymerization? The images are taken from Google Images). Condensation Polymerization. To help readers understand the difference between addition polymerization and condensation polymerization, we have created a list of differences. A lesson on addition polymerisation and condensation polymerisation with links made to the AQA Chemistry specification throughout. The Basic Difference Between Addition and Condensation Polymerization is that Addition Polymerization involves only one monomer and does not lead to a loss in smaller molecules e.g PVC and Teflon while Condensation Polymerization involves two different kinds of monomers and lead to loss of simple molecules like HCl etc. Polymers can be classified into 2 types as per their preparation process they undergo – Addition polymerization and Condensation Polymerization. This process does not involve the formation of any by-products. Addition polymerization: This is the type of polymerization in which the molecules of a similar monomer or different monomer add up together on a large scale to form a polymer. those Monomers having either a double bond or triple bond are called, those Monomers having two similar or different functional groups are called. The Basic Difference Between Addition and Condensation Polymerization is that Addition Polymerization involves only one monomer and does not lead to a loss in smaller molecules e.g PVC and Teflon while Condensation Polymerization involves two different kinds of monomers and lead to loss of simple molecules like HCl etc. Difference Between Isotropic And Anisotropic, Difference Between Pure Substance And Mixture, Importance of Carbon and Water in Biochemistry with Reactions, Periodic table Relative Atomic Masses in tabular form, Effective Nuclear Charge in Periodic Table with General Formula, Graham’s Law of Diffusion: Statement & Formula. 1. In condensation polymerization, each step of the process is accompanied by the formation of a molecule of some simple compound, often water. Is the chain growth process usually much slower than the step-growth process? What is the difference between Addition and Condensation Polymerization? The two major types of polymerization are addition polymerization and condensation polymerization. (Have to include images in this section. all polymers are resulted by the Addition of monomers. In addition polymerization, there are three distinct steps. Let us do a comparative analysis of the two types of polymerization to understand them better. There are two methods by which polymers are made: Addition polymerisation Condensation polymerisation In addition polymerisation, alkenes add to themselves. One method is a type of chemical reaction called a condensation reaction.In a condensation reaction, two molecules combine with the loss of a smaller molecule, usually water, an alcohol or an acid. In organic chemistry, reactions are described which occur between different functional groups. The addition polymerization definition is that this is the process of repeated addition of monomers. 1) Addition polymers are thermoplastics. In addition polymerization, monomers react to form a polymer without the formation of by-products. First, dimers, trimmers, and tetramers are formed. Two classes of polymerization usually are distinguished. It is important for readers to remember that condensation polymerization is a type of step-growth polymerization. Required fields are marked *, Difference Between Addition and Condensation Polymerization. Addition polymerization and condensation polymerization are two modes of polymerization reactions in the formation of polymers. ; Condensation polymerisation forms the polymer molecule and one water molecule per linkage. Polyaddition refers to the process in which polymers are formed by carrying out an addition reaction between species of all degrees of polymerization. for example nylon, bakelite. Condensation polymers can be either thermoplastics or thermosetting plastics. Unit 2: ENERGY, RATE AND CHEMISTRY OF CARBON COMPOUNDS. 1.Discuss the differences between condensation and addition polymerization. Polymerisation. This can be done in the presence of catalysts or bacterial enzymes. In condensation polymerization, each step of the process is accompanied by the formation of a molecule of some simple compound, often water. Polymerization is of two types, condensation polymerization and addition polymerization. Mention the process in which the molecular weight of polymers almost remains unchanged while the entire process progresses. Condensation Polymerization. Polymerisation The polymerisation techniques used in industry are different for condensation and addition polymerization this is basically due to the differences in … According to experts, an addition polymer is a polymer that is formed by simply linking monomers. Step growth polymerization is the formation of a polymer from bi-functional or multi-functional monomers. 2. Some examples of condensation polymers are mentioned below. The end groups remain reactive through the entire process. Before we look at the difference between addition polymerization and condensation polymerization, it is important to understand exactly what addition polymers and condensation polymers are. These polymers are formed by carrying out condensation reactions. In the process of addition polymerization, what does the entire reaction contain at any point in time? Condensation polymers, on the other hand, are formed by linking monomers. For example, when ethylene is polymerized to make polyethene, every atom (present in the monomer) of ethylene becomes a part of the polymer. In most cases, these products include water. In this process, more than one different monomers are used to form small molecules like HCl, water, and ammonia as by-products. The molecular weight of the resultant polymers is a multiple of the monomer’s molecular weight. Chain initiation—usually by means of an initiator which starts the polymerization process. Addition and condensation polymerization are the two major processes of producing a polymer compound. In condensation polymerization, there is no termination step. in this type of polymerization, no molecule is eliminated, and often one monomer takes part in it. Let’s look at the table below to understand the difference between both of these polymerization reaction groups. But in condensation polymerization, any molecule can react with any other. Process Improvements and Polymerization Kinetics Process Technology. many of the small molecules are eliminated such as ammonia and water etc. In this process, the polymers are formed when condensation reactions are carried out between species of all degrees of polymerization. For instance, a carboxylic acid group can react with an amine group … for example nylon, bakelite. Because of this reason, these polymers are non-biodegradable and very difficult to recycle. Answer: In the addition polymerization process the total molecular weight of the polymers remains almost unchanged with the increasing conversion. This process can also be done through condensative chain polymerization. Based on this kind of reaction, one can state that polymerization is divided into two groups. But before that, let’s start at the very beginning. As this addition proceeds further a long molecular chain is formed. Both additional and condensation polymerizationentail formation of large molecules (Polymers) with repeating structure fromsmall molecules (monomers). In polymerization. You might also be interested to know that addition polymers include strong C-C bonds. 2.What requirement should be provided to achieve high yield and high molecular weight of polymer by condensation reaction? Condensation and addition polymerization are the two most common methods for polymer synthesis. ; This is a key difference between condensation polymers and addition polymers: Addition polymerisation forms the polymer molecule only. 2) Condensation polymerisation involves the elimination of small molecules; Addition polymerisation does not. Lewis acids or bases, radical initiators are used as catalysts. The main difference between addition polymerisation and condensation polymerisation is that the addition polymerisation refers to the production of addition polymers by the addition of olefinic monomers without the production of any kind of by-product, whereas the condensation polymerisation refers to the production of condensation polymers by the intermolecular condensation of two different … Another process related to the formation of condensation polymers is polycondensation. Further, the total molecular weight of the polymers increases during the step-growth process. The reaction that results in the elimination of by-products while forming polymers is condensation polymerization. One such important product is called a monomer. Let’s learn some interesting facts about the difference between addition and condensation polymers. In this process, the molecules that are removed are water and HCl. Vedantu academic counsellor will be calling you shortly for your Online Counselling session. Wales. These results can also be achieved through polyaddition. 3) Condensation polymerisation involves 2 functional groups within the monomers; Addition only one (C=C). Now, readers must understand the meaning of addition and condensation polymers. In this reaction, the molecules are joined together by losing small molecules as by-products. Pro Lite, Vedantu these small molecules are known as building blocks and called as monomers. (Have to include images in this section. Some examples of addition polymers are mentioned below. 1. This is done without the co-generation of other by-products. Answer. Answer: At any point in time, the process of addition polymerization contains free radical chains and initiators, full-grown polymer molecules, and unreacted monomer molecules. Unlike in chain growth polymerization, the polymer chains here are not formed at the beginning. Addition polymerisation is a process involving many small, unsaturated monomers combining to form one large polymer molecule. In condensative chain polymerization, the polymers are formed by sequential addition or the condensation reaction of the monomers to an active site in a chain reaction. Initiation, propagation and finally termination. These monomers possess double or triple bonds to form polymers. Polymerization is defined as the process of combining a large number of small molecules to form a single macromolecule. Get more information in … This would give the readers an idea of what is addition polymerization and what is condensation polymerization. Sorry!, This page is not available for now to bookmark. Some by-products include ammonia, water, and HCl, This process also results in the addition of monomers to form polymers, In this process, monomers are condensed to form polymers, If one wishes to find out the molecular weight of the final polymers, then all one needs to do is multiply the molecular weight of all monomers, The total molecular weight of the final product cannot be found by multiplying the molecular weight of all the monomers, In addition polymerization, Lewis acids, Lewis bases, and radical initiators are used as catalysts, Different molecules are used as catalysts in the process of condensation polymerization, Some common examples of addition polymerization are polyethylene, Teflon, and PVC, Some common examples of condensation polymerization are bakelite, nylon, and silicon. To understand condensation reactions, let's look at another hypothetical polymer reaction. What Is The Difference Between Molecule And Compound? The terminal functional groups on a chain remain active, so that groups of shorter chains combine into longer chains in the late stages of polymerization.
