Abstract
A polymer of fluorine-containing sulfonated poly(arylene ether)s and a manufacturing method thereof are provided. The polymer is formed by processing a nucleophilic polycondensation between a fluorine-containing monomer having an electron-withdrawing group and a multi-phenyl monomer. A main structure of the polymer of fluorine-containing sulfonated poly(arylene ether)s has a first portion with fluoro or trifluoromethyl substituted phenyl groups, and a second portion with sulfonated phenyl groups.
