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4 h;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。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, 4 h and TEBA as phase transfer catalyst. Anionic polymerization of VEAA in THF was also carried out with 1, 1-diphenyl-hexyllithium （DPHL） as catalyst. The molecular weight was found to be controllable and mono-disperse polymers were obtained.
