多缩乙二醇/甲基丙烯酸的酯化反应研究

Study on the Esterification of PEG/MAA

研究了多缩乙二醇（PEG）与甲基丙烯酸（MAA）的酯化反应，考察了催化剂、阻聚剂、反应介质、温度和PEG分子量等因素对酯化反应速率和多缩乙二醇二甲基丙烯酸酯（PDEGMA）纯度及转化率的影响，获得了PEG／MAA酯化反应的适宜条件及最佳原料配比。

The author studied the esterification reaction of polyethylene glycol (PEG) with methylacrylic acid(MAA) and the effect of catalysts,polymerization retarders,reactive media, temperatures and PEG molecularweights on the esterification rate, purity and contersion rate of polydiethyleneglycolmethacryate (PDEG MA).The suitable reactive conditions and optimum feedstock ratio are found.
