采用溶液聚合制备了一系列线形的丙烯酸羟乙酯和丙烯酸酯的共聚物，测定共聚物样品的特性粘度，用ＦＴＩＲ和１ＨＮＭＲ对共聚物进行了分析．用溶液成膜法研究了这类共聚物与酚氧树脂的共混相容性．ＤＳＣ的结果显示：该共聚物仅和酚氧树脂部分相容，丙烯酸羟乙酯单元对丙烯酸甲酯与酚氧的相容性无明显影响．表明侧链导入羟基并未增加丙烯酸甲酯对酚氧树脂的氢键特殊相互作用． A series of linear copolymers of hydroxyethyl acrylate and acrylate were prepared by solution polymerization. The intrinsic viscosity of copolymer samples was determined. The copolymers were analyzed by FTIR and 1HNMR. The compatibility of these copolymers with phenoxy resin was studied by solution film formation. DSC results showed that the copolymer was only partially compatible with the phenoxy resin and the hydroxyethyl acrylate units had no significant effect on the compatibility of methyl acrylate and phenolic oxygen. It was shown that the introduction of hydroxyl groups into the side chains did not increase the hydrogen bond special interaction of methyl acrylate and phenoxy resin.
