Abstract
AbstractThe structure of poly(phthalidylidenearylene)s, synthesized by electrophilic substitution reactions, was studied using 1H and 13C NMR spectroscopy. Homopolycondensation of 3‐aryl‐3‐chlorophthalides 1a – d in nitrobenzene leads to para‐substituted linear polymers 2a – d, whereas polycondensation of phthaloyl dichloride and bis[4‐(3‐chloro‐3‐phthalidyl)phenyl] ether (6) with diphenyl ether results in polymers 5 containing irregular units.
