## Abstract Poly(ether‐ester)s from (2,2‐bis(1,4‐phenyleneoxy)‐propylidene)‐diacetic acid and related diacids with diphenols were synthesized using several ammonium and phosphonium salts as phase transfer catalysts. The best results were obtained with benzyltriethylammonium chloride, which is a hyd
