Abstract
The present invention provides a novel vinyl silicone monomer which contain urethane functional groups. These materials are used as an intermediates in the preparation of polymers. The vinyl reactive silicone urethane intermediates are prepared by the reaction of hydroxy containing silicone compounds with Benzene-1-(1-isocyanato-1-methylethyl)-3-(1-methylethenyl).
