摘要

介绍了一种以再生聚对苯二甲酸乙二醇酯(PET)为原料制备聚酯酰胺的方法。用傅里叶红外光谱研究了氨解过程。研究了延长氨解过程的时间和增加聚酯的用量对聚酯酰胺工艺性能的影响。试验结果表明，所研制的聚酯酰胺可作为环氧低聚物的硬化剂。

Production of polyesteramides based on recycled PET and low molecular weight amine

A method for the obtaining of polyesteramides based on recycled polyethylene terephthalate (PET) is presented. The process of aminolysis is studied by FTIR spectroscopy. The eff ect of increasing the duration of the aminolysis process and the amount of PET on the complex of technological properties of polyesteramides is shown. According to the test results, the developed polyesteramides can be used as hardeners for epoxy oligomers.
