ABSTRACT:
New, easily processable, polyaromatic esters were prepared from 2,2'-diiododiphenyl-4,4'-dicarbonyl dichloride, isophthaloyl chloride and/or terephthaloyl chloride in combination with 4,4'-isopropylidene diphenol, 4,4'-sulfonyldiphenol, or resorcinol by interfacial condensation. In these polymers, phenylacetylenyl groups can be easily introduced into the polymer chain by replacing the iodine. This process leads to soluble and curable polymers from which films can be prepared. After curing the polymers are insoluble and show excellent thermal and chemical resistance. The curing process increases the polymers' softening temperature about 20.degree. C.
