Partly sulfonated polyepichlorohydrin was synthesized by phase transfer catalytic reaction of linear polyepicholohydrin oligmer and sulfite. 用相转移催化聚环氧氯丙烷与亚硫酸盐反应合成磺酸聚醚。
The multiblock copolymers exhibit good emulsifying properties and good phase transfer catalystic properties in Williamson reaction. 并研究其乳化性能和相转移催化性能。
