    摘要: This invention provides method for the preparation of carbinol-modified organopolysiloxane which does not suffer from the secondary reaction problems of the art and which thereby makes possible the production of high-purity carbinol-containing organopolysiloxane.The method involves a platinum-catalyzed addition reaction of an organopolysiloxane having at least 1 silicon-bonded hydrogen atom in each molecule and an organic compound whose molecule contains at least 1 aliphatically unsaturated hydrocarbon group and at least 1 triorganosilyl-blocked carbinol group. Thereafter a desilylation reaction on the organopolysiloxane product is accomplished in an essentially water-free mixture of organic carboxylic acid and alcohol to provide carbinol-modified organopolysiloxane.
