Abstract:
A method for making a polyisobutylene diol from a polyisobutylene diallyl. The method includes hydroborating the polyisobutylene diallyl to produce a polyisobutylene dialkyl borane, and oxidizing the polyisobutylene dialkyl borane to form the polyisobutylene diol. The polyisobutylene diallyl is hydroborated by combining in situ the polyisobutylene diallyl with a borane-coordinating solvent, an alkaline metal salt of borohydride, and an acid. The alkaline metal salt of borohydride is combined with the polyisobutylene diallyl before the acid is combined with the polyisobutylene diallyl.

Claim (Index 4):
The method of  claim 1 , wherein the acid includes a strong Lewis acid, a halide, or a combinations thereof; the strong Lewis acid including at least one of boron trichloride, aluminum trichloride, and aluminum trifluoride; and the halide including at least one of iodine and bromine.
