1-(4'-AMINOPHENYL)-3-AMINOETHYLADAMANTANE - A MONOMER FOR THE SYNTHESIS OF POLYIMIDES AND COPOLYIMIDES EXHIBITING THE ENHANCED HYDROLYTIC STABILITY

摘要

FIELD: organic chemistry and technology. SUBSTANCE: product: 1-(4'-aminophenyl)-3-aminoethyladamantane. Invention relates to the synthesis of new adamantane-containing diamine ensuring to obtain polyimides and copolyimides based on pyromellite dianhydride, 4,4'-diaminodiphenylether and 1-(4'-aminophenyl)-3-aminoethyladamantane. The content of the latter compound in polymers is 70-100 mole %. EFFECT: enhanced hydrolytic stability of polyimide and copolyimide films.
