摘要： 合成了一系列含环氧基团的丙烯酸酯聚合物(HGMB),并对其改性环氧树脂/4,4'-二氨基二苯基甲烷的抗冲性能、动态力学行为进行了考察.结果表明:当改性体系中加人质量分数为15%的HGMB(甲基丙烯酸缩水甘油酯、甲基丙烯酸羟乙基酯、甲基丙烯酸甲酯、丙烯酸丁酯的摩尔分数分别为4.3%,5%,25.7%,65%)时,与空白体系相比,改性体系的冲击强度提高50%,且玻璃化温度有所提高,模量没有降低.

Abstract: A series of epoxide-containing acrylic polymer modifiers (HGMB) were synthesized.The dynamic mechanical behavior and impact strengths of the modified systems,epoxy resin E-51/4, 4'-diaminodiphenylmethane (DDM)/HGMB, were investigated.Theresults showed that both the structure and amount of the modifiers affected the impactstrength and modulus of the modified systems significantly.The addition of 15%(mass fraction) HGMB(4.3% glycidyl methacrylate(GMA), 5 % hydroxyethyl methacrylate(HEMA),25.7% methyl methacrylate (MMA) and 65 % butyl acrylate (BA) (mole fraction)) resultedin a 50% increase in impact strength and an obvious increase in Tg of the modified system butonly little loss of its modulus.

Key words: epoxy resins, modification, acrylate copolymer
