| 摘 要： | 在相转移催化剂存在下，以2-氯乙烯醚和丙烯酸钠为原料设计合成了双官能团单体2-乙基乙烯基醚丙烯酸酯，研究了相转移剂的种类以及反应条件对反应的影响。结果表明最佳反应条件为：2-氯乙烯醚/丙烯酸钠物质的量比5∶1；反应温度110℃；反应时间4h；以三乙基苄基氯化铵(TEBA)为相转移剂效果最佳。随后在一定的温度下，以1，1-二苯基己基锂（DPHL）为催化剂，以2-乙基乙烯基醚丙烯酸酯为单体在四氢呋喃中进行了阴离子聚合，得到分子量可控的单分散的聚合物。

| Abstract: | In the presence of a phase transfer catalyst, 2-vinyloxyethyl acrylate (VEAA) was synthesized via the reaction of 2-chloroethyl vinyl ether and sodium acrylate. The effects of varying the catalyst and reaction conditions were investigated. The results showed that the optimum reaction conditions were: molar ratio of 2-chloroethyl vinyl ether to sodium acrylate, 5∶1; reaction temperature, 110℃; reaction time, 4h and TEBA as phase transfer catalyst. Anionic polymerization of VEAA in THF was also carried out with 1,1-diphenylhexyllithium (DPHL) as catalyst. The molecular weight was found to be controllable and mono-disperse polymers were obtained. |
