Patent ID: 8552118

Claim:
A method for producing a primary alcohol-terminated polyisobutylene compound comprising the steps of: (A) providing an allyl-terminated polyisobutylene having at least two allyl termini, wherein the allyl termini are formed by the addition of straight C 3 to C 12 allyl groups having a double bond present at the end of the allyl group; (B) subjecting the allyl-terminated polyisobutylene to anti-Markovnikov bromination to form a primary bromine-terminated polyisobutylene compound having at least two primary bromine termini; (C) converting the primary bromine-terminated polyisobutylene compound to a primary alcohol-terminated polyisobutylene via a base reaction, the primary alcohol-terminated polyisobutylene having at least two primary alcohol termini; and (D) recovering the primary alcohol-terminated polyisobutylene.
