Which of the following polymerization processes best describes formation of polyisobutylene?

Question

Quizplus · Accepted Answer

Polyisobutylene is formed through chain growth addition polymerization process. This is because the monomer units (isobutylene) are added one by one to the growing polymer chain without any elimination of small molecules such as water or HCl, which is characteristic of chain growth polymerization. Furthermore, the polymerization reaction is activated by a catalyst such as a Lewis acid or a cationic initiator, which facilitates the initiation and propagation steps of the reaction.
