Patent ID: 8362167

Claim:
A composition consisting of: (a) a fluorocarbon polymer selected from the group consisting of: wherein m=42-70 mol %, n=25-55 mol %, and p=1-5 mol %; wherein m=42-70 mol %, n=25-55 mol %, and p=1-5 mol %; and wherein m=42-70 mol %, n=25-55 mol %, p=1-4 mol %, and α=1-7 mol %; and (b) a curing agent selected from the group consisting of wherein R f 1 is selected from the group consisting of straight chain, branched secondary or branched tertiary C 1 -C 6 and C 8 -C 20 perfluoroalkyl groups optionally containing ether or thioether linkages and C 1 -C 10 perfluoroalicyclic groups optionally containing ether or thioether groups; R f 2 is a straight or branched C 4 -C 6 and C 8 -C 20 perfluoroalkylene group optionally substituted with ether and thioether linkages; and X is wherein R f 1 is as defined above; and wherein n=4, 5, 7, or 8, and m=0, 1, 2, 3, 4, 5, or 7.
