The process is initiated by a Lewis acid. When the initiator is cationic in nature, in addition to the double bond, it would generate a cationic intermediate for propagation of the chain process and is termed as cationic addition polymerization. This mode of polymerisation leading to an increase in chain length or chain growth can take place through the formation of either free radicals or ionic species. The monomers used are unsaturated compounds, e.g., alkenes, alkadienyls and their derivation. In this type of polymerisation, the molecules of the same monomer or different monomers add together on a large scale form a polymer. The addition and condensation polymers are nowadays also referred to as chain growth polymers and step growth polymers depending on the type of polymerization mechanism they undergo during their formation.Īddition polymerisation or chain growth polymerisation: Using the Polymer Chemistry notes PDF, you can learn how experts have solved queries.
