【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SO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。更多还原

【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 SO 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.更多还原
