ISOBUTENE POLYMER FUNCTIONALIZATION BY MEANS OF HYDROBORATION

摘要

The invention borane per mole and 0.5 to 1.8 equivalents of a source of borane , borane per mole of molecular weight less than 250 or by treatment with the reaction product of an alkene with , the present invention relates to a method for functionalizing isobutene polymers having a terminal olefinic unsaturation by treatment of the isobutene polymer with the borane source in the presence of an alkene . The reaction mixture is stirred , and is easy to maintain low viscosity .
