PROCESS FOR MAKING SI-H FUNCTIONAL SILOXANE OLIGOMER

摘要

The present invention relates to a method of making a Si-H functional siloxane
oligomer from the reaction between silicon hydride compounds and cyclic
siloxane oligomer in the presence of a Lewis acid that is capable of
interacting with the hydrogen of the silicon hydride to promote ring opening
of the cyclic siloxane oligomer and the insertion a siloxane oligomer segment
between Si and H atom to thereby form the Si-H functional siloxane oligomer.
