Synthesis and characterization of novel soluble polyester-imide containing heterocyclic groups

Herein, we report the synthesis and characterization of novel monomer diacid for preparation various poly(ester-imide)s. two novel porous poly(ester-imide)s with different heterocyclic groups are synthesized through an polycondensation of 5-((4-nitrophenyl)amino)isophthalic acid and two dioles containing heterocyclic rings, N-methylpyrrolidone as solvent, triphenyl phosphite and pyridine as dehydrating agent, by means of regulating the mole ratio of the monomers. The structures of the novel chiral compounds synthesized in this investigation were identified using TLC and FTIR. Thermogravimetric analysis (TGA) indicated that the incorporation of heterocyclic ring and imide structure could enhance the char yield and thermal stability of polymers
