Synthesis and properties of a novel polyester containing bithiazole

A novel Schiff base type polyester containing 2,2′-diamino-4,4′-bithiazole (DABT) was prepared by low-temperature interface polycondensation of 1,4-benzenedicarbonyl dichloride with 4,4′-(4,4′-bithiazole-2,2′-diylbis(imine-2,1-diyl)diphenol (BDDP), which is derived from a 2,2′-diamino-4,4′-bithiazole (DABT) Schiff base reacted with a 4-hydroxybenzaldehyde monomer. The newly generated polyester was evaluated based on characterization of its solubility, FTIR spectroscopy, elemental analysis, X-ray diffraction measurements and thermogravimetric analysis (TGA) studies.
