  Synthesis and characterization of new polyesters based on 2,5-bis[(4-chloro carboxyanilino) carbonyl] pyridine and aromatic diols

  摘要：

  Six new polyesters 7a-f were synthesized through the solution polycondensation reaction of diacid chloride 5 with six aromatic diols 6a-f in NN-dimethyl acetamide (DMAc) as solvent in the presence of pyridine as base. The polycondensation reaction produced a series of novel polyester containing pyridyl moiety in the main chain in high yields with inherent viscosities between 0.35 and 0.54 dL/g. The resulted polymers were fully characterized by means of FT-IR spectroscopy, elemental analyses, inherent viscosity and solubility tests. Thermal properties of these polymers were investigated by using thermal gravimetric analysis (TGA) and differentional thermal gravimetric (DTG). The glass-transition temperatures of these polyesters were recorded between 130 and 170 degrees C by differential scanning calorimetry (DSC) and the 10% weight loss temperatures were ranging from 390 to 450 degrees C under nitrogen.
