摘要：

A study of the relationship between glass transition temperature of various polyimides and their conformational parameters is presented. The dependence of glass transition temperature on the rigidity of either diamine or dianhydride component is discussed by selecting groups of polymers based each on one diamine and different dianhydrides. The solubility of such polymers is also discussed in connection with the rigidity of their chains.
