PROCESS FOR SYNTHESIZING POLYMERS AND USE THEREOF FOR PRODUCING ANHYDROUS MEMBRANES FOR FUEL CELLS

摘要

The present invention relates to a process for synthesizing a polymer comprising at least one unit of formula (I), n being an integer, characterized in that said process contains at least one nucleophilic substitution step, in which a polymer comprising at least one unit of formula (II) is substituted with 1-benzyl-2-hydroxymethylimidazole (2) in order to result in a polymer comprising at least one unit of formula (III), and the benzyl protective group is cleaved.
