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 16):
The method as recited in  claim 1 , further comprising subjecting the product of step d) to an esterification reaction comprising the steps of:\n e) forming a mixture by combining the functional polyisobutylene of step d) with an organic solvent, methacrylic anhydride and a catalyst and reacting the mixture at a temperature from 40 to 80\u00b0 C. for a period of time from 30 minutes to 3 hours to thereby form a functional polyisobutylene having at least one (meth)acrylate terminal end.
