NOVEL RHODIUM-CONTAINING SELECTIVE CATALYST FOR SYNTHESIS OF EPOXYSILOXANE OR EPOXY- SILICONE MONOMER AND POLYMER

摘要

The invention provides a method for making a curable epoxysilicone composition through the hydrosilation reaction between an ethylenically unsaturated epoxide and an SiH-containing silicone to produce an epoxysilicone product, and catalyzed by a rhodium containing selective catalyst which does not promote the oxirane ring-opening reaction of either the ethylenically unsaturated epoxide starting material or the opoxysilicone product. The invention also provides for a curable epoxysilicone composition made by the above method for the catalyst, and two methods of making the catalyst.
