摘要：

Polyimides containing 1,4-dithiine units and corresponding thiophene units were synthesized by the nucleophilic substitution reaction of bis(dichloro-maleimide) arylene derivatives with sodium sulfide. Their structures were confirmed by IR and UV spectroscopy and elemental analysis. The polymers were characterized by viscosimetric measurements, softening points and thermogravimetric data.
