Patent ID: 7935768

Claim:
A crosslinked fluoroaromatic polymer comprising at least one polymer having fluorinated aromatic segments and the at least one polymer is selected from the group consisting of the following: wherein C n F 2n and C m F 2m are each a linear or branched perfluorocarbon chain, n is a number of from about 1 to about 100, m is a number of from about 1 to about 6, x is a number of from about 1 to about 500, and a, b, and c are molar ratios wherein a is a number of from about 0.25 to about 0.75, b is a number of from about 0.25 to about 0.75, c is a number of from about 0.01 to about 0.25, and a+b+c=1, and wherein the crosslinked fluoroaromatic polymer is crosslinked at the fluorinated aromatic segments via a nucleophilic curing agent.
