Claim:
A silane of general Formula (1): [Y[-G(—SiX u Z b v Z c w ) s ] r ] n (Formula 1) wherein: each occurrence of G is a divalent straight chain alkyl of 3 to 18 carbon atoms or a chemical bond; each occurrence of X is independently selected from the group consisting of R 1 O—, R 1 C(═O)O— and —O(R 10 CR 11 ) f OH, wherein each occurrence of R 1 , R 10 and R 11 is independently R; each occurrence of Z b is independently (—O—) 0.5 , and [—O(R 10 CR 11 ) f O—] 0.5 , wherein each occurrence of R 10 and R 11 is independently R; each occurrence of Z c is independently given by —O(R 10 CR 11 ) f O— wherein each occurrence of R 10 and R 11 is independently R; each occurrence of R is independently an alkyl of C 1 to C 4 or hydrogen; each occurrence of the subscript f is an integer from 1 to 15; each occurrence of n is an integer from 1 to 100, with the proviso that when n is greater than 1, then v is a greater than 0 and all the valences for Z b have a silicon atom bonded to them; each occurrence of the subscript u is an integer from 0 to 2; each occurrence of the subscript v is an integer from 0 to 3; each occurrence of the subscript w is an integer 0 or 1, with the proviso that u+v+2w=3; each occurrence of the subscript r is 1; each occurrence of the subscript s is 1; and each occurrence of Y is independently CH 2 ═CH—, CHR═CH— or CR 2 ═CH—, with the proviso that said silane contains at least one occurrence of Z b or Z c .
