Abstract

The thermal and thermomechanical properties of copolyimides based on pyromellitic dianhydride, 4,4'-diaminodiphenyloxide and [2-(aminomethyl)bicyclo [2.2.1]hept-3-yl]anilines in an inert medium have been studied for the first time. It is shown that the introduction into the structure of aromatic polyimides up to 20 mol %. asymmetric vicinally substituted bicyclic diamines allows to obtain materials with increased hydrolytic stability in comparison with fully aromatic polyimides while maintaining a high level of thermomechanical characteristics.
