The morphology of the resulting PS/poly（St-co-EGDMA） particles was dependent on the crosslinker concentration and polymerization temperature.展开更多
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′-...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′-blthiazole （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.展开更多
