Patent ID: 7638589

Claim:
A polymer of Formula 1: (W) a (R 2 ) b —Si(R 1 ) 2 —O—[Si(R 1 ) 2 —O] n —[Si(W) c (R 1 ) d (R 2 ) e —O] m —Si(R 1 ) 2 —(W) f (R 2 ) g 1 wherein: a, b, c, d, e, f and g are each independently 0 or 1, provided that (a+b) is 1, (f+g) is 1, and (c+d+e) is 2, each R 1 is a C 1 to C 8 alkyl, each R 2 is independently H or C 1 to C 8 alkyl, optionally containing oxygen, nitrogen, or sulfur, or a combination thereof, n=0 to 500, m=1 to 100, each W is independently (R f —X—A—X) p —Y—X wherein: R f is a straight or branched perfluoroalkyl group having from about 2 to about 20 carbon atoms, or a mixture thereof, which is optionally interrupted by at least one oxygen atom, each X is independently an organic divalent linking group having from about 1 to about 20 carbon atoms, optionally containing oxygen, nitrogen, or sulfur, or a combination thereof, A is a 1,2,3-triazole, p=1 to 2, and Y is O, N, or NR wherein R is H or C 1 to C 20 alkyl, optionally containing oxygen, nitrogen, or sulfur, or a combination thereof.
