摘要：
The invention relates to a sulfonated, aromatic polymer comprising the recurring structural unit of formula (I): -O-Ar1(SO3R)n-C(CF3)2-Ar1(SO3R)n-O-Ar?2-(X-Ar2)¿m-, wherein Ar?1 and Ar2¿ represent independently of each other bivalent aromatic or heteroaromatic substituted radicals that may contain one or several monovalent organic groups which are inert under actual operating conditions, R represents hydrogen, an alkaline or alkaline earth ion or an ammonium ion, n is a whole number from 0 to 3, m is 0, 1 or 2 and X represents a group -CO-, -O-, -C¿p?H2p-, -CpF2p- or -S-, wherein p is a whole number from 1 to 10. These polymers can be processed into membranes with a high proton conductability. Preferably, said membranes are used in fuel cells.
