摘要
扼要介绍了聚酰胺酯的制备方法,重点讨论了聚酰胺酯的研究进展及其结构与性能的关系。在聚酯中引入酰胺基可制得多种类型的改性聚酯,如提高模量,增加原聚酯的吸湿性,改善熔融行为等,并可制得弹性纤维。聚酰胺酯是兼具聚酯和聚酰胺两者优良性能的一类材料。
The synthesis technique of polyesteramide are briefly discussed, and the study on structure - property relationship of polyesteramide are summrised in detail. The polyester can be modified by introducing amide group in macromo-lecular chains to improve its moisture absorption as well as melting behavior. Segmented polyesteramide with long soft block exhibit thermorplastic elastimatic property.
