摘要
以1,2,4-偏苯三酸酐、二元醇和一元醇为反应单体,采用溶液法和熔融法合成了具有芳香型结构的超支化聚酯。合成产物采用红外、核磁、GPC、粘度等进行了表征,并详细研究了反应条件对合成产物结构的影响。
Aromatic hyperbranched polyesters （HBP） were synthesized by 1,2,4-benzenetricarboxylic anhydride, diols and monohydric alcohols using solution polymerization and melting polymerization. The synthetic products were characterized by Fourier Transform Infrared Spectroscopy （FTIR）, ^1 H-NMR and gel permeation chromatography（GPC） and inherent viscosity. The effects of reaction conditions on the structure of synthetic products were also investigated.
