METHOD FOR END-CAPPING A POLYSILOXANE PREPOLYMER

A method is disclosed which involves the steps of (a) reacting a polysiloxane prepolymer having reactive functional end groups with a non-free radical polymerizable reactive end-capping agent; and (b) reacting the reaction product of step (a) with a free radical polymerizable reactive end-capping ag...
