Claim:
A fluorosilane represented by (L) 3 -Siâ€”(CH 2 ) n â€”(Z 1 ) a â€”[C(X 1 )] x â€”(Z 2 ) l -Q 1 -R f Formula 1 wherein: each n is independently an integer from 1 to 12; a=1, x=1, and l=1; L is independently chosen from a hydrolysable or non-hydrolysable monovalent group R f is chosen from a C 2 -C 12 perfluoroalkyl provided that: i) one fluorine atom of the perfluoroalkyl can be optionally replaced by hydrogen, and/or ii) the perfluoroalkyl can be optionally interrupted by at least one oxygen, methylene, or ethylene; Q 1 is chosen from the group consisting of a C 2 -C 12 hydrocarbylene optionally interrupted by at least one divalent organic group; X 1 is chosen from O or S; Z 1 is â€”NHâ€” and Z 2 is from the group consisting of â€”NHâ€”, â€”Sâ€”, â€”NHâ€”S(O) 2 â€”, â€”N[C(O)H]â€”, â€”[HC(COOH)(R 1 )]CHâ€”Sâ€”, and â€”(R 1 )CHâ€”[HC(COOH)]â€”Sâ€”; provided that when Z 1 is â€”NHâ€” and Z 2 is â€”NHâ€”, then Q 1 is chosen from the group consisting of a C 2 -C 12 hydrocarbylene interrupted by at least one divalent organic group; each R 1 is independently chosen from hydrogen, phenyl, or a monovalent C 1 -C 8 alkyl optionally terminated by â€”C 6 H 5 , preferably H or CH 3 .
