Polyimides of different structures were synthesized by reaction of 1,4phenylene diisocyanate (PPDI) and 1,5-naphthalene diisocyanate (NDI) with pyromellitic dianhydride (PMDA) and 3,3Π,4,4Π-benzophenonetetracarboxylic dianhydride (BTDA). Polyamide-imides were also prepared by reaction of PPDI and ND
A series of novel polycyclic aliphatic polyamides was synthesized by direct polycondensation of the 1,6-diamantane dicarboxylic acid with various alicyclic diamines in N-methyl-2pyrrolidone (NMP) containing lithium chloride, using triphenyl phosphite and pyridine as a condensing agent. The polyamide
