To draw the structure of butyl rubber which is formed by the polymerization of isoprene and isobutylene in the presence of cationic initiator. Concept introduction: Cationic polymerization is the type of polymerization in which the cationic initiator transfers the charge to the monomer unit which then becomes reactive to proceed for further reaction. This reactive monomer further reacts to the same or other monomer to give the final product as polymer . Reactivity of monomer towards the cationic polymerization increases as the stability of the carbocation intermediate formed increases. Some examples of initiator used are: HClO 4 , H 2 SO 4 , CFCOOH etc., in all these initiators H + acts as an cationic initiator which starts the polymeric reaction. Here the butyl rubber formed is a copolymer because it has two different monomer units.

Question

Definition Definition Chemical process in which one or more monomers combine to produce a very large chain-like molecule called a polymer. The functional groups present on the monomers and their steric effects are responsible for polymerization through a sequence of reactions that vary in complexity. There exists a stable covalent chemical bond between monomers that sets apart polymerization from other processes.
