Abstract
A method for making a hydrocarbon oxysilyl functional polymer, which is important as a modified silicone or silicone-modified polymer, by a hydrosilylation reaction between a hydride (hydrocarbonoxy)silane compound having SiH functional groups and a polymer having olefinic or acetylenic unsaturated groups in the presence of a carboxylic acid and a catalytic amount of platinum or a platinum compound.
Claims11
A method for making a hydrocarbonoxysilyl functional polymer comprising reacting a polymer having olefinic or acetylenic unsaturated groups with a hydride (hydrocarbonoxy) silane compound described by formula
- HRnSi(OR1)3−n
- in the presence of platinum or platinum compound catalyst and a silylated carboxylic acid compound;
- where each R is an independently selected hydrocarbon group comprising 1 to 10 carbon atoms, each R1 is an independently selected hydrocarbon group comprising 1 to 10 carbon atoms, and n is 0,1 or 2, wherein the platinum or platinum compound catalyst is a complex of chloroplatinic acid and divinyltetramethyldisiloxane.
