ABSTRACT:
The invention provides a method for making an epoxysilicone compound through the hydrosilation addition reaction between an ethylenically unsaturated epoxide and an SiH-containing silicon to produce an epoxysilicone product, and catalyzed by a regiospecific hydrosilation catalyst which does not also promote an oxirane ring-opening polymerization reaction in either the ethylenically unsaturated epoxide starting compound or in the epoxysilicone hydrosilation reaction product. The invention also provides a hydrosilation catalyst with the above catalytic properties as well as an epoxysilicone composition made by the above method.
