The invention pertains to an improved silane of general Formula (1):
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ [Y[-G(-SiX u Z b v Z c w ) s ] r ] n €ƒ€ƒ€ƒ€ƒ€ƒ(Formula 1)
wherein each occurrence of G is independently chosen from a group consisting of a chemical bond and a polyvalent group containing from 1 to 30 carbon atoms derived from an alkyl, alkenyl, aryl, aralkyl and heterocarbon; each occurrence of X is independently selected from the group consisting of-Cl, -Br, R 1 O-, R 1 C(=O)O-, R 1 R 2 C=NO-, R 1 R 2 NO- or R 1 R 2 N-, -R 1 , -(OSiR 1 R 2 ) t (OSi R 1 R 2 R 3 ), and -O(R 10 CR 11 ) f OH, wherein each occurrence of R 1 , R 2 , R 3 , R 10 and R 11 is independently R; each occurrence of Z b is independently [-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 chosen independently from a group consisting of a straight, cyclic, branched alkyl, alkenyl, aryl, and aralkyl groups containing from 1 to 20 carbon atoms, a molecular component derived from a heterocarbon containing 1 to 20 carbon atoms and hydrogen; each occurrence of Y is independently CH 2 =CH-, CHR=CH- or CR 2 =CH-; 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, 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 3, each occurrence of the subscript v is an integer from 0 to 3, each occurrence of the subscript w is an integer from 0 to 1, each occurrence of the subscript r is an integer from 1 to 6, each occurrence of the subscript t is an integer from 0 to 50, each occurrence of the subscript s is an integer from 1 to 6; with the provisos that u + v +2 w =3 and the silane composition contains at least one occurrence of Z b or Z c . |
