Patent ID: 8569420

Claim:
A method for producing a primary alcohol-terminated polyisobutylene compound comprising the steps of: (A) providing an alkenyl-terminated polyisobutylene having exactly one alkenyl terminus, wherein the one alkenyl terminus is formed from a straight C 3 to C 12 alkenyl group having a double bond present at the end of the alkenyl group; (B) subjecting the alkenyl-terminated polyisobutylene to a bromination reaction to form a primary bromine-terminated polyisobutylene compound having one primary bromine terminus; (C) converting the primary bromine-terminated polyisobutylene compound to a primary alcohol-terminated polyisobutylene via a base reaction, the primary alcohol-terminated polyisobutylene having exactly one primary alcohol terminus; and (D) recovering the primary alcohol-terminated polyisobutylene.
