Abstract:
Disclosed is a simplified process for formation of polyisobutylene functionalized with at least one terminal primary or secondary alcohol. The process comprises subjecting an olefin functional polyisobutylene, butyl rubber, or mixtures thereof to ozonation and reduction thereby forming mono-alcohol and diol functional polyisobutylene. The formed functional polyisobutylenes can serve as precursors for many other functionalized polyisobutylenes including urethane polyisobutylenes, urethane polyisobutylenes capped with (meth)acrylate functions, and (meth)acrylate capped polyisobutylenes.

Claim (Index 1):
A method of forming a functional polyisobutylene having at least one terminal primary or secondary hydroxyl group comprising the steps of:\n a) providing at least one polymer selected from the group consisting of: an olefin functional polyisobutylene, the olefin functional polyisobutylene optionally including at least one internal phenyl group; butyl rubber; and mixtures thereof; b) solubilizing the polymer in an organic solvent to form a polymer solution; c) subjecting the polymer solution to ozonation by bubbling ozone through the polymer at a temperature in the range of from +10\u00b0 C. to a temperature that is greater than the freezing temperature of the polymer solution, optionally in the presence of a sulfide catalyst; d) treating the product of step c) at a temperature from 0 to 100\u00b0 C. in the presence of a reducing agent thereby forming a functional polyisobutylene having at least one terminal primary or secondary hydroxyl group.
