Patent ID: 8198472

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 X is independently selected from the group consisting of R 1 O—, R 1 C(═O)O— and —R 1 , wherein each occurrence of R 1 is independently an alkyl group, an alkenyl group, an aryl group or and aralkyl group containing from 1 to 20 carbon atoms or a hydrogen; each R 10 and R 11 is independently an alkyl group, an alkenyl group, an aryl group, or an aralkyl group containing 1 to 20 carbon atoms or a hydrogen; each occurrence of Y is independently a monovalent organofunctional group selected from the group consisting of: —O—CH 2 —C 2 H 3 O, —C 6 H 9 O, —CR 6 (—O—)CR 4 R 5 , —NR 4 C(═O)OR 5 , —OC(═O)NR 4 R 5 , —NR 4 C(═O)SR 5 , —SC(═O)NR 4 R 5 , —NR 4 C(═S)OR 5 , —OC(═S)NR 4 R 5 , —NR 4 C(═S)SR 5 , —SC(═S)NR 4 R 5 , maleimide, maleate, substituted maleate, fumurate, substituted fumurate, —CN, citraconimide, —OCN, —N═C═O, —SCN, —N═C═S, —SC(═S)OR 4 , —SC(═S)SR 4 , —SC(═O)SR 4 , —NR 4 C(═O)NR 5 R 6 , —NR 4 C(═S)NR 5 R 6 , R 4 C(═O)NR 5 —, —C(═O)NR 4 R 5 —, and R 4 C(═S)NR 4 —; —OH, —OR 4 , —SR 4 , —S—SR 4 , —S—S—SR 4 , —S—S—S—SR 4 , melamine and cyanurato wherein each occurrence of R 4 , R 5 and R 6 is independently an alkyl group, an alkenyl group, an aryl group, or an aralkyl group containing 1 to 20 carbon atoms or a hydrogen; and each occurrence of the subscript f is independently an integer from 1 to 15.
