摘要：以双官能团环氧树脂和双酚Ａ为单体，制备高分子量苯氧树脂，通过ＦＴＩＲ对其分子结构进行分析后，将１０ｗｔ％苯氧树脂加入到Ｅ－４４环氧树脂中，用ＤＳＣ，冲击仪和ＳＥＭ等对增韧效果的分析测定，固化反应活化能降低９％，冲击强度提高６３．２％，玻璃化温度提高了２８℃。
The high molecular weight phenoxy resin was synthesized by using relatively low molecular weight difunctional epoxy resin and bisphenol A as polymerization raw materials. The basic structures were analysed by FTIR. 10% phenoxy resin was entered into E-44 epoxy resin. The effect of toughness were characterized by DSC, impact resiliometer and SEM. The result showed that activite energy of cure reaction was degraded 9%, impact strength was raised 63.2% and Tg was raised 32%.
