Patent ID: 8420826

Claim:
A fluorosilane represented by (L) 3 -Si—(CH 2 ) n —(Z 1 ) a —[C(X 1 )] x —(Z 2 ) l -Q 1 -R f Formula 1 wherein: each n is independently an integer from 1 to 12; 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 2 is —NH— and Z 1 is from the group consisting of —O—, and —S—; each R 1 is independently chosen from hydrogen, phenyl, or a monovalent C 1 -C 8 alkyl optionally terminated by —C 6 H 5 , preferably H or CH 3 .
