Silicone-urethane copolymers
 
Regan of AdvanSource Biomaterials Corporation, Massachusetts, formed silicone urethane copolymers from a reaction mixture of a diisocyanate, a polycarbonate diol, a polysiloxane, a C2-8 diol chain extender, and optionally a monofunctional siloxane chain terminator under an inert gas in the presence of a catalyst to initiate a one-step polymerization reaction.  The temperature of the reaction mixture is monitored, and the admixing step is terminated when the reaction mixture reaches a predefined temperature. The material can be further crosslinked by heating in an oven for a suitable period of time to ensure completion of the reaction. (RDC 8/29/2012)
