ABSTRACT:
The polyesters of trans-4,4'-stilbenedicarboxylic acid, 5-95 mol % 1,4-butanediol, and 95-5 mol % 1,6-hexanediol can be injection-molded to give shaped objects having exceptionally high tensile strength and stiffness. Many of the copolyesters of this invention have excellent chemical resistance and good hydrolytic stability. The copolyesters can be injection-molded, spun into fiber, or extruded into film having these properties.
