Types of Polymers on the basis of Method of Preparation

Question

Commercial polyisobutylene (PIB or butyl rubber) is synthesized via cationic polymerization. Explain why it cannot be made through free radical or anionic polymerization

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.
