摘要：

Some new polyimides containing bithiazole rings were prepared by reacting 2,2'-diamino-4,4'-bisthiazole with different aromatic dianhydrides. The polyimides obtained had inherent viscosities of 0.37-0.82 dL/g. Thermogravimetric analysis of the polyimides showed good thermal stability, the temperature at 5% weight loss being from 450 degrees C to 560 degrees C. The permeability of two polymer membranes to H-2, O-2 and N-2 was determined.
