Patent ID: 6936686

Claim:
A cross-linked silicone gel substantially free of SiO 2 groups, substantially free of SiO 1.5 groups, and substantially free of polyalkyleneoxide groups, comprising a cross-linked polymerization product of (A) (i) an α,ω-di loweralkenyl terminated polyorganosiloxane of formula I having a molecular weight of about 20,000 to about 25,000 with n being about 265 to about 340 and each R1 being independently H, or an alkyl group of 1 or 3 carbons and (ii) optionally an α,ω-di ethylene terminated polydiphenyldimethylorganosiloxane; and (B) a polyorganohydosiloxane of formula II where the molecular weight of reactant II is about 3500 to 4000; q is about 5 to about 9; p is about 40 to about 50, and each R2 is independently an alkyl of 1-3 carbon atoms; said polymerization product being polymerized in the presence of a medium selected from the group consisting of hydrocarbon oils, and mixtures thereof; and (C) said medium wherein said polymerization takes place initially with mixing and said mixing is halted when gelling is visibly seen.
