Patent ID: 7399887

Claim:
A compound of Formula I, wherein Y is a bond or C m H 2m−p (OA) p wherein m is 0 to 4, and p is 0 or 1, X′ is X or H, X is CH 2 CH 2 OA, CH(CH 2 OA) 2 , C(CH 2 OA) 3 , or X and X′ combine to form (CH 2 CH 2 ) 2 NCH 2 CH 2 OA or (CH 2 CH 2 ) 2 O, provided that when X and X′ combine to form (CH 2 CH 2 ) 2 O then Y is CH 2 CH(OA)CH 2 , A is CF 2 CFHO—R f or H, R f is C n F 2n+1 wherein n is an integer of 1 to about 6, M is a cation having a charge equal to a, and a is a positive integer equal to 1 or 2, provided that at least one of X, X′, or Y contains A equal to CF2CFHO—R f .
