FIELD: chemistry.
SUBSTANCE: described are polyimides and copolyimides based on dianhydride of 3,4,3',4'-tetracarboxydiphenyloxide, asymmetric bicyclic diamines: 3-[(2-aminomethyl)bicyclo[2.2.1]hept-3-yl)aniline and 4-[(2-aminomethyl)bicyclo[2.2.1]heptt-3-yl]aniline and 9,9-bis-(4-aminophenyl)fluorene of general formula: 
where n=20-100 mol %, m=80-0 mol %, temperature for 5% reduction in weight of which lies in the range 400-500°C, meant for production of hydrolytically and thermally stable polyimide materials.
EFFECT: obtaining hydrolytically and thermally stable bicyclo-containing polyimides and copolyimides.
