| 摘 要： | 以磺酸盐类物质为改性单体,采用共聚法制得水溶性聚酯(WSP),用FTIR、DSC、X射线衍射等测试分析方法对WSP进行表征;研究WSP中改性单体的添加量对其水溶性能、结晶性能及热性能的影响。研究结果表明:通过傅里叶红外变换光谱分析确定了分子链中SO的存在,由此证明SIPE参加了共聚反应;增加改性单体的用量可有效提高共聚酯的水溶性,但其对共聚酯的结晶不利。

| Abstract: | Water-soluble polyester(WSP) was prepared by adding modifying monomer with sulfonic group through copolymerization.And the WSP was characterized by FTIR、DSC and X-ray.The effects of modifying monomer on WSP′s water-solubility and crystallization and thermal property were studied.And the results show that the existence of SO in the molecular chain is confirmed by FTIR,thus proving that SIPE has participated in the copolymerization;and increasing modifying monomer improves the water-solubility of polyester effectively,but it is disadvantageous to its crystallization. |

| Keywords: | water-soluble polyester modifying monomer crystallization capacity SIPE super-fine fiber |
