Abstract:
1. A polymer composition comprising: a) at least one fluorinated ionisable polymer (A), which comprises recurring fluorinated blocks and recurring functional blocks, each of said recurring functional blocks comprising at least one ionisable anionic group, and wherein at least one of said recurring functional blocks of polymer (A) is between two fluorinated blocks; b) at least one fluorinated ionisable polymer (B), which comprises recurring fluorinated blocks and recurring functional blocks, each of said recurring functional blocks comprising at least one ionisable cationic group, and wherein at least one of the said recurring functional blocks of polymer (B) is between two fluorinated blocks; wherein the ratio between the ionic equivalents of polymer (A) and the ionic equivalents of polymer (B) ranges from 1.1 to 0.9.
