PROCESS FOR THE PREPARATION OF CROSS-LINKED FLUORINATED POLYMERS |
摘要 |
A process for the preparation of cross-linked fluorinated polymers comprising sulfonic acid functional groups comprising the steps of: a) providing at least one fluorinated polymer (P) comprising at least one -SO3M functional group and less than 2% of -SO2F functional groups with respect to the total amount of -SO3M and -SO2F functional groups, wherein each M is selected from H and alkaline metals; and b) reacting said fluorinated polymer with at least one cross-linking agent of formula R(X)n under conditions that promote the formation of covalent bonds between the at least one functional group -SO3M of fluorinated polymer (P) and at least one functional group X of the cross-linking agent. |
