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.
4,4'-(HexaΒ―uoroisopropylidene)-bis-(phthalic anhydride) (1) was reacted with L-leucine (2) in toluene solution at reΒ―uxing temperature in the presence of triethylamine and the resulting imideacid (4) was obtained in quantitative yield. The compound (4) was converted to the diacid chloride (5) by rea
A series of novel benzhydrol-containing poly(amide-imide)s (PAIs) have been prepared from a new diimide-dicarboxylic acid, N,N'-bis(4-hydroxycarbonyl)-benzhydrol-3,3',4,4'-tetracarboxydiimide (BHTDA-DIA), with various diamines by direct polycondensation using triphenyl phosphite and pyridine as cond
