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'-(Hexa¯uoroisopropylidene)-bis-(phthalic anhydride) (1) was reacted with L-leucine (2) in toluene solution at re¯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
A series of novel soluble poly(amide-imide)s were prepared from the diimide-dicarboxylic acid, 2,2-bis[N-(4-carboxyphenyl)-phthalimidyl]hexafluoropropane, with various diamines by the direct polycondensation in N-methyl-2-pyrrolidinone containing CaCl 2 using triphenyl phosphite and pyridine as cond
