SYNTHETIC METHOD FOR PREPARING DUAL CURABLE SILICONE COMPOSITIONS

摘要

A synthetic method for preparing dual curable (e.g., thermal and light curable) silicone compositions is provided. The first step being a, chemical modification of silanichydride bonds in cyclic siloxane monomer by the hydrosilylation reaction with acrylate-/methacrylate-containing allylic monomer. The second step being a ring-opening polymerization of the acrylate-/methacrylate-functionalized cyclic siloxane monomer with siloxane monomers using an oligosiloxane as a chain terminator.
