Eight novel poly (imide-sulfonamide) s have been prepared by reacting pyromellitic dianhydride and benzophenone tetracarboxylic acid dianhydride with variously substituted dianilines containing preformed sulfonamide linkages. Inherent viscosities of the prepared polymers ranged from 0.13 t o 0.53 dL

Novel poly(amide imide)s having inherent viscosities in the range 0.89-1.56 dL/g were prepared by the method of low temperature polycondensation in solution of N,N-dimethylacetamide (DMA) from aromatic diamines and a new monomer: N-[4"-(chloroformylphenyl) -4'-iminobenzoyl] trimellitimide chloride.
Two new series of poly(imide-ester)s and poly(imide-urethane)s have been synthesized from various N,N@-bis(u-hydroxyalkyl)pyromellitimides (HAPMIs). The poly(imide-ester)s were prepared from terephthalic acid with HAPMIs by melt polycondensation while poly(imide-urethane)s were obtained from HAPMIs
The synthesis and characterization of a series of poly(amic methyl ester)s from five aromatic dianhydrides and a diamine, 4,4-oxydianiline (ODA), are described. These poly(amic ester)s are obtained by the low-temperature polycondensation from dianhydrides derived diester-diacyl chlorides and ODA in
