US 2014/0350278 A1 · Polymerizable Hybrid Polysiloxanes and Preparation

Abstract

The present invention relates to a process of making a polymerizable hybrid polysiloxane or a polymerizable hybrid siloxane. The process includes reacting an organopolysiloxane or organosiloxane having an average of at least 3 silicon hydride (SiH) groups per molecule, a polyoxyethylene, and a catalyst. The process also optionally includes adding a stabilizer, a catalytic inhibitor, a solvent, and an unsaturated reactant selected from substituted and unsubstituted unsaturated organic compounds.
