采用1,4 -丁烯二醇和亚硫酸氢钠反应合成了1,4-二羟基丁烷-2-磺酸钠,经甲醇/水混合溶剂提纯,产率90％以上.红外光谱(FT- IR)、核磁氢谱(1H- NMR)和碳谱(13C- NMR)证实了产物的结构,并对其物理性质(如熔点)和其在水、丙酮、甲醇等中的溶解性进行了测试.研究了反应温度、反应时间、反应物物质的量比对产率的影响,结果表明:反应温度为40℃,反应时间为3h,亚硫酸氢钠与1,4-丁烯二醇的物质的量比为1.2:1是合成1,4-二羟基丁烷-2-磺酸钠的最佳反应条件.以1,4-二羟基丁烷-2-磺酸钠为含离子的单体,聚己二酸己二醇新戊二醇酯(PHNA)、异佛尔酮二异氰酸酯(IPDI)、乙二胺(EDA)、1,4-丁二醇(BDO)为原料,采用丙酮法合成了聚氨酯离子聚合物,红外光谱证实了其结构.拉伸测试表明聚氨酯离子聚合物拉伸强度达41.3 MPa,断裂伸长率为1700％；聚氨酯离子聚合物分散后对分散体的基本性能进行测试,结果显示ξ电位为- 53.85 mV,说明分散体具有良好的稳定性；固含量为50.6％,黏度320 mPa·s,说明聚氨酯分散体具有高固含量、低黏度的特征.
