摘　　要：以聚对苯二甲酸乙二醇酯(PET)为基体,引入第三单体间苯二甲酸乙二醇酯-5-磺酸钠(SIPE)和第四单体间苯二甲酸(IPA),通过直接酯化-缩聚工艺路线合成水溶性共聚酯,系统研究了二元酸配比、SIPE添加量对共聚酯的合成和常规性能的影响,利用核磁共振定性分析了共聚酯的大分子链序列结构。结果表明SIPE主要影响共聚酯的流动性能和常规性能,IPA主要影响共聚酯的耐热性能。核磁表明SIPE和IPA均成功引入共聚酯大分子链结构中,且符合多单体改性和高比例IPA改性的分子序列结构特点。The water-soluble co-polyester were synthesized by direct esterification-condensation routes, introducing dimethyl isophthalate-5-sodium sulfonate （SIPE） as third monomer and isophthalic acid （IPA） as fourth monomer into polyethylene terephthalate （PET） macromolecular chains.The effects of binary acid ratio, SIPE amount on water-soluble co-polyester s synthesis and conventional performance were studied.The macromolecular chain sequence structure of co-polyester were analyzed by nuclear magnetic resonance.The results showed that SIPE had significant effect on the flow performance and conventional performance of copolyester. NMR showed that both SIPE and IPA were successfully introduced into the copolyester.
