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
A modified new aromatic diamine 2,5-bis[(4-aminophenyl)4-benzamide]-3,4-diphenyl thiophene ( VI) with preformed amide linkages and pendant phenyl substituents was synthesized, characterized by IR, NMR, mass spectroscopy, and a physical constant. Novel poly(amide-amide)s were synthesized from VI and
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.
