PROCESS FOR MAKING SILOXANE POLYMERS

摘要

The present invention relates to process for making a siloxane polymer which comprises at least one Si-OH group and at least one Si-OR group, where R is a moiety other than hydrogen, comprising reacting one or more silane reactants together in the presence of a hydrolysis catalyst in either a water/alcohol mixture or in one or more alcohols to form the siloxane polymer; and separating the siloxane polymer from the water/alcohol mixture or the alcohol(s).
