Abstract
Optically active polyesters were synthesized from chiral (2R,4R)-pentane-2,4-diol or its analogues and various aromatic diacid chlorides in refluxing 1,2-dichloroethane in the presence of pyridine. The resulting polyesters had inherent viscosities of 0.22–0.57 dl g−1, and specific rotation from +4° to −421°. The glass transition temperatures of the polymers were in the range from 66°C to 147°C and their initial decomposition temperatures were around 280°C. No remarkable difference in thermal behavior was observed between the optically active polyesters and optically inactive polymers derived from the corresponding racemic diols.
