Polypyromellitimides have been synthesized from carbazole and N-benzylcarbazole by a two-step procedure involving ring-opening polyaddition with pyromellitic dianhydride and subsequent thermal cyclodehydration. The physicochemical, thermal and dielectric properties of the polymers have been studied.

Polycondensation of 1,3-bis(aminopropyl)-1,1,3,3-tetramethyldisiloxane with pyromellitic dianhydrid or with pyromellitic diester-diacid yielded polymers, which are soluble in organic solvents and suitable for injection moulding at 180 "C. When 1,3-bis(m-aminophenyl)-1,1,3,3-tetramethyldisiloxane was
## Abstract Three new thermally stable polypyromellitimide films were made by the thermal cyclodehydration of the corresponding polyamic acids obtained by the polymerization of pyromellitic dianhydride with 4,4β²βbis{N^2^β[4β(4βaminobenzyl)phenyl]aspartimido} diphenylmethane, 4,4β²βbis{N^2^β[4β(4βami
