Title:
COMPOSITIONS OF IONISABLE FLUOROPOLYMERS
Document Type and Number:
WIPO Patent Application WO/2013/017470
Kind Code:
A1
Abstract:
The invention relates to a composition of ionisable fluoropolymers, in particular to polymer compositions 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 in which polymer (A) at least one of the said recurring functional blocks is comprised 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 in which polymer (B) at least one of the said recurring functional blocks is comprised 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.
