Dibasic acids containing a pyromellitimide ring were synthesized by the reaction of pyromel-litic dianhydride with such ?-aminoacids as glycine, e-amino-caproic acid and p-amino-benzoic acid. By the condensation polymerization of the dibasic acids obtained above with diamines, polypyromellitimide-amides were synthesized. The polymers were soluble in m-cresol and sulfuric acid, and the inherent viscosities of the polymers ranged from 0.21 to 0.42 (in m-cresol). The polymers were found to be considerably heat-stable. |
