Patent ID: 8475937

Claim:
A silicone composition comprising: (A) a hydrolysis product prepared by reacting (a) at least one thiophenyl-substituted silane having the formula Th—(CH 2 ) m+2 SiR 1 n X 3-n , and (b) a cross-linking agent selected from (i) at least one silane having the formula (R 3 b SiX 4-b ), (ii) at least one organic compound having an average of at least two silyl groups per molecule, wherein the silyl groups have the formula —SiR 3 c X 3-c , and (iii) a mixture comprising (i) and (ii), with water in the presence of an organic solvent to form an organic phase containing the hydrolysis product and an aqueous phase, and separating the organic phase from the aqueous phase, wherein R 1 is C 1 to C 10 hydrocarbyl free of aliphatic unsaturation, X is a hydrolysable group, Th is thiophenyl or substituted thiophenyl, R 3 is C 1 to C 10 hydrocarbyl or —H, m is 0 to 10, n is 0, 1, or 2, b is 0 or 1, and c is 0, 1, or 2; and (B) an organic solvent.
