摘　　要：本文采用本实验室制备的一种RAFT链转移剂,先与酚醛环氧树脂进行加成反应,然后通过控制丙烯酸的量再对加成后树脂进行改性,制备出了水溶性酚醛树脂;采用FTIR、GPC、DSC等测试手段对树脂的结构进行了表征,并对其性能进行了研究。实验发现,当酚醛环氧树脂和丙烯酸的摩尔比为1"15时,制备的改性酚醛环氧树脂不但溶于水,而且能溶于乙醇、丙酮等有机溶剂。210℃热处理10min后,树脂由水溶变成水不溶。该树脂有望在水显影热敏树脂体系中得到应用。In this essay,the chain transfer agent RAFT made in our laboratory has a reaction with phenolic epoxy resin.Then the resin is changed by controlling the quantity of the acrylic acid and the water soluble phenolic resin was prepared.We characterised the modified resin with the method of FTIR,GPC,DSC etc.The results indicate that the resin can dissolve in the water and common organic solvents,when n（phenolic epoxy resin）：n（acrylic acid）=1：15.After being heated at 210℃ for 10 min,the modified resin can not dissolve in water.The resin can be possibly used in the heat-sensitive system.
