摘要
阐述了间苯二甲酸二甲酯－５－磺酸钠等第三单体对阳离子染料可染聚酯染色改性的作用；介绍了我国的生产情况和存在问题，以及第三单体在非纤维方面的应用。
This paper reviews the role of sodium5sulfodimethyl isophthalate (SIPM)played on the modification of polyester with improved cationic dyeable behaviour and introduces the production situation of SIPM,the problems currently existed and its application in nonapparel industries.
