Patent ID: 8158812

Claim:
A silane of the general formula: wherein each occurrence of G is independently a polyvalent group derived from an alkyl, alkenyl, aryl or aralkyl group with G containing from 1 to 30 carbon atoms; each occurrence of R 10 and R 11 is independently a hydrogen, an alkyl group, an alkenyl group, an aryl group, an aralkyl group, or a monovalent heterocarbon group containing 1 to about 20 carbon atoms; each occurrence of Y is independently a monovalent organofunctional group chosen from the group consisting of mercapto, acryloxy, methacryloxy, —O—CH 2 —C 2 H 3 O, —C 6 H 9 O, —CR 6 (—O—)CR 4 R 5 , —NH 2 , —NHR 4 , —NR 4 R 5 , —NR 4 -L 1 -NR 5 R 6 , —NR 4 -L l (-NR 5 R 6 ) 2 , —NR 4 -L 1 -NR 5 -L 2 -NR 6 R 7 , —NR 4 -L 1 (-NR 5 R 6 ) 3 , —NR 4 -L 1 -NR 5 -L 2 -NR 6 -L 3 -NR 7 R 8 , and —NR 4 -L 1 -N(-L 2 NR 5 R 6 ) 2 , wherein each occurrence of L 1 , L 2 and L 3 is selected independently from the meanings given for G and each occurrence of R 4 , R 5 , R 6 , R 7 and R 8 is independently a hydrogen, an alkyl group, an alkenyl group, an aryl group, an aralkyl group, or a monovalent heterocarbon group containing 1 to about 20 carbon atoms;, each occurrence of X is independently selected from the group consisting of —Cl, —Br, R 1 O—, R 2 C(═O)O—, R 1 R 2 C═NO—, R 1 R 2 NO—, R 1 R 2 N—, —R 1 , -(OSiR 1 R 2 ) t (OSiR 1 R 2 R 3 ), and —O(R 10 CR 11 ) f OH, wherein each occurrence of R 1 , R 2 , and R 3 is independently selected from the group consisting of straight alkyl, cyclic alkyl, branched alkyl, alkenyl, aryl, aralkyl group containing from 1 to 20 carbon atoms, and hydrogen; each occurrence of the subscript f is independently an integer from 1 to 15; each occurrence of the subscript t is independently an integer from 0 to 50; and the subscript n is an integer from 3 to 100.
