Abstract

AbstractPolyesters were made with aromatic diacid chlorides and 4,4,‐thiodiphenol. Isophthaloyl chloride and/or terephthaloyl chloride were used as acid chlorides alone or together with 5‐cyanoisophthaloyl chloride or [2.2]p‐cyclophane‐3,9‐dicarboxylic acid chloride. The latter components were incorporated in order to make the polymers useful for crosslinking. A polyether could be obtained by polycondensation of 2,4‐dichloro‐benzonitrile and 4,4′‐thiodiphenol. The polycondensations were run in nitrobenzene as solvent.
