The Friedel-Crafts polymerization of 2,5-thiophenedicarbonyl dichloride and diphenyl ether in 1,2-dichloroethane afforded only low molecular weight of poly(ether ketone) containing thiophene-ring. In contrast to this, the polymerization in 1-butyl-3-methylimidazolium chloride-aluminum chloride mixture gave high molecular weight polymers. The polymerization in ionic liquid was a new approach to expand possibility of polymer synthesis such as preparation of polymer containing heterocyclic rings. The obtained poly(ether ketone) exhibited good thermal stability and chemical resistance comparable to common poly(ether ketone)s.
