摘要：
The invention pertains to a process for the purification from ionic impurities of a fluoroionomer liquid composition, said process comprising: - providing a liquid composition comprising at least one fluoroionomer (1-1) in a liquid medium, said liquid composition comprising ionic impurities; and - contacting said liquid composition with a solid particulate comprising at least one fluoroionomer (I-2) having ion exchange groups, wherein H
+ Or OH
- ions are bound to at least a fraction of said ion exchange groups, and - separating said liquid composition from said solid particulate.
