CROSS-LINKABLE POLYMERS COMPRISING SULFONIC ACID FUNCTIONAL GROUPS

摘要

The present invention pertains a fluoropolymer [polymer (F)] comprising: - recurring units derived from at least one ethylenically unsaturated fluorinated monomer [monomer (FM)]; - from 5% to 60% by moles [with respect to the total moles of recurring units of polymer (F)] of recurring units derived at least one ethylenically unsaturated fluorinated monomer containing at least one -SO2F functional group [monomer (IO)]; and - from 0.01 % to 10% by moles [with respect to the total moles of recurring units of polymer (F)] of recurring units derived from at least one monomer comprising an azide group [monomer (Az)], to a process for its manufacture, to a cross-linkable composition comprising the same, to a process for cross-linking the same and to articles comprising the cross-linked polymer.
