摘    要:以1,4-丁二醇、己二酸和乙醇胺为原料合成了聚'(己二酸/丁二醇-co-己二酸/乙醇胺)(PBEA)预聚体,再以对苯二甲酰双己内酰胺(TBC)为扩链剂对其进行扩链,合成出了高分子量的聚酯酰胺。研究了预聚体分子量、扩链剂/预聚体摩尔比、反应温度等因素对扩链反应的影响。在扩链温度为220?℃,预聚体的分子量为1700左右,扩链剂/预聚体的摩尔比为1.1时,扩链效果最好,所得PBEA的特性黏度达082dL/g。并采用GPC和DSC分别对扩链前后的聚酯酰胺的分子量和熔点进行了表征,发现其分子量成倍增加,而熔点则有所降低。

Abstract:The HO terminated prepolymer of poly(butylene adipate co amidoethyl adipate) (PBEA) was prepared by the polycondensation of adipic acid with ethanolamine and excessive 1,4 butanediol. Polyesteramide PBEA with high molecular weight was synthesized by a chain extending reaction from the HO terminated PBEA prepolymer with terephthaloyl bis caprolactamate (TBC) as chain extender under reduced pressure in bulk state. The influencing factors on the chain extending reaction were studied. At 220℃ and TBC/PBEA prepolymer molar ratio of 11, the PBEA with intrinsic viscosity of 082?dL/g was obtained. The PBEA prepolymer and the chain extended PBEA were also characterized by GPC and DSC spectra, respectively. The molecular weight of the PBEA after the chain extension was increased evidently but the melting point decreased.
Keywords:polyesteramide  aminoethanol  chain-extending reaction  terephthaloyl bis-caprolactamate
