The condensation polymerization produces low molecular weight polymers as its end products, and they are biodegradable and easy to recycle compared to addition polymers. Condensation polymers form: when bifunctional monomers react to form a long chain polymer molecule; small molecules, such as water, are eliminated during the reaction; Polyesters, polyamides, proteins and polysaccharides such as cellulose, are all examples of condensation polymers. Since addition polymerization has rapidly growing chains and free monomer as its reactants, and condensation polymerization occurs in step-wise fashion between monomers, dimers, and other smaller growing chains, the effect of a polymer molecule's current size on a continuing reaction is profoundly different in these two cases. Ultimately the reaction stops when two radicals join together and form a stable bond. The unsaturated bonds in these molecules are used to form bonds between the carbon atoms to form large chains that may be branched and cross-linked. These two groups are addition polymerization and condensation 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) condensation) versus Chain-Growth (e.g. These monomers add together to form a long chain to form a product with spe… The monomer for polyethylene is ethene (CH2=CH2). Side by Side Comparison – Addition Polymerization vs Condensation Polymerization in Tabular Form Learn about other similar topics like the difference between Enantiomers and Diastereomers by registering with BYJU’S. The kinetic treatment of condensation polymerization focuses on the step‐growth mechanism, with a separate section devoted to cases of living polycondensation. Addition polymers do not produce by-products, whereas the condensation polymerisation produces by-products. It involves the linking of monomers with double bonds. Let us do a comparative analysis of the two types of polymerization to understand them better. Condensation polymerization occurs when monomers bond together through condensation reactions. In addition polymerization, the monomer molecules bond to each other without the loss of any other atoms. Your email address will not be published. An addition polymer is a polymer that forms by simple linking of monomers without the co-generation of other products. These two groups are addition polymerization and condensation polymerization. In organic chemistry, reactions are described which occur between different functional groups. water. But in condensation polymerization, any molecule can react with any other. Imagine that two people (each a monomer) stand close together and each person has his/her arms folded (double bond). As nouns the difference between polymerization and copolymerization is that polymerization is (chemistry) the chemical process, normally with the aid of a catalyst, to form a polymer by bonding together multiple identical units (monomers) while copolymerization is the polymerization of multiple monomers to form a copolymer. The two people now make a polymer, and the process can be repeated. There are many differences between the two processes. Citing Literature . Unlike in chain growth polymerization, the polymer chains here are not formed at the beginning. Terms of Use and Privacy Policy: Legal. First, dimers, trimmers, and tetramers are formed. In condensation polymerization, each step of the process is accompanied by the formation of a molecule of some simple compound, often water. Available here    Compare the Difference Between Similar Terms. Unlike in chain growth polymerization, the polymer chains here are not formed at the beginning. Whereas other compounds are of relatively low molar mass, polymers are giant molecules of very high molar mass. Addition polymers are those formed from monomers without the loss of a small molecule, meaning there is bond opening. Condensation polymerization definition is - polymerization in which a single molecule is eliminated —distinguished from addition polymerization. Available here, 1.’Polymerisation PE generique’ By Cdang – Own work, (Public Domain) via Commons Wikimedia, Filed Under: Chemistry Tagged With: addition polymers, condensation polymers. The catalysts in condensation polymerization are catalysts in condensation polymerization. the conversion … These monomers bind with each other via covalent bonds to form a polymer. Any condensation process that results in the formation of polymers, is the condensation polymerization. Common examples of addition polymerization are PVC, polyethene, Teflon etc. Addition polymerisation produces addition polymers through the addition of olefinic monomers without the formation of any by-product. The process of synthesizing addition polymers is addition polymerization. Polymers are generally formed by the addition of a network of structural units or small molecules called monomers. 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.
