Abstract:
1. A free flowing filler composition comprising at least one organofunctional silane and at least one particulate filler, the silane(s) having a chemical structure selected from the group consisting of: each occurrence of Y is independently selected from a polyvalent species (Q) z A(=E), wherein the atom (A) attached to an unsaturated heteroatom (E) is attached to a sulfur, which in turn is linked by means of a group G 2 to a silicon atom; each occurrence of R is independently selected from the group consisting of hydrogen, straight, cyclic or branched alkyl that may or may not contain unsaturation, alkenyl groups, aryl groups, and aralkyl groups, wherein each R, other than hydrogen, contains from 1 to 18 carbon atoms; each occurrence of G each occurrence of G each occurrence of X is independently selected from the group consisting of —Cl, —Br, RO—, RC(═O)O—, R each occurrence of Z each occurrence of Z each occurrence of Q is independently selected from the group consisting of oxygen, sulfur, and (—NR—); each occurrence of A is independently selected from the group consisting of carbon, sulfur, phosphorus, and sulfonyl; each occurrence of E is independently selected from the group consisting of oxygen, sulfur, and (—NR—); each occurrence of the subscripts, a, b, c, f, j, k, m, n, p, q, r, s, u, v, w, and z is independently given by a is 0 to about 7; b is 1 to about 3; c is 1 to about 6; f is about 2 to about 15, j is 0 to about 1, but j may be 0 only if p is 1; k is 1 to 2, with the provisos that if A is carbon, sulfur, or sulfonyl, then (i) a+b=2 and (ii) k=1; if A is phosphorus, then a+b=3 unless both (i) c>1 and (ii) b=1, in which case a=c+1; and if A is phosphorus, then k is 2; m is 1 to about 20, n is 1 to about 20, p is 0 to 5, q is 0 to 6; r is 1 to 3; s is 1 to 3; u is 0 to 3; V is 0 to 3; w is 0 to 1 with the proviso that u+v+2w=3; z is 0 to about 3; and with the proviso that the each of the above structures contains at least one hydrolysable group, Z
