Synthesis and Characterization of Polyamide Containing Maleimide Pendant Group

Document Type: Research Paper



A series of new polyamides containing maleimide pendant group were prepared by low
temperature polycondensation of 5-(4-(2,5-dioxo-2H-pyrrol-1(5H)-yl)benzamido)isophthaloyl
chloride as a new monomer with various aromatic diamines in NMP. Monomer and polymers
structures were identified through FT-IR, 1H-NMR and elemental analysis. Obtained polymers
were soluble in polar solvents and non soluble in aprotic solvents. The inherent viscosities of
the polymers have been determined in NMP and had values from 0.35 to 0.39 dL/g. Thermal
stability of polymers was investigated with thermal gravimetry analysis (TGA) and diffraction
scanning calorimetry (DSC). Also thermal behavior of monomer was studied with DSC analysis.
X-ray diffraction measurement was used to indicate amorphous structure of polyamide
