Abstract:
1. A rubber composition comprising an unsaturated elastomer in an amount greater than 5 weight percent of the rubber composition and a sulfur-functional linear polyorganosiloxane chosen from those of formulae (I), (II) and (III); wherein A is a polyvalent radical group ((R R G is a divalent aliphatic radical, a divalent cycloaliphatic radical, or a divalent aromatic radical; R S is one or more sulfur atoms; L is independently at each occurrence a monovalent or a polyvalent group derived by substitution of an aliphatic radical, a cycloaliphatic radical, or an aromatic radical; Q is oxygen, sulfur or an NR J is carbon, sulfur, phosphorus, or a sulfinyl group; E is oxygen or sulfur; “m” and “n” are independently an integer greater than 0; “p” is greater than 0; “t” is an integer that is equal to 0, 1, 2, 3, 4, or 5; “j” is equal to 0 or 1; “k” is equal to 1 if J is carbon, sulfur or sulfinyl, “k” is 2 if J is phosphorus; and “z” is an integer that is equal to 0, 1, or 2.
