Polymers were first classified according to polymerization method by Wallace Carothers in 1929, who introduced the terms addition polymer and condensation polymer to describe polymers made by addition reactions and condensation reactions respectively. However this classification is inadequate to describe a polymer which can be made by either type of reaction, for example nylon 6 which can be made either by addition of a cyclic monomer or by condensation of a linear mon… WebAn example of chain growth polymer is.

Web24.2: Chain-Growth Polymers—Addition Polymers. Polymers are long chain giant organic molecules are assembled from many smaller molecules called monomers. Polymers consist of many repeating monomer units in long chains. A polymer is … Rubber is an example of an elastomer type polymer, where the polymer has the … WebChain-growth polymerization forms polymers in a similar fashion to adding links to a chain. Addition. Addition reactions take place by combination of monomers with two reaction sites; the monomers are added to the growing polymeric chain. A typical example of addition of PE polymerization is illustrated in Fig. 5.6. new england 45 70 prices
