摘　　要：采用含羧基的酰亚胺对环氧树脂进行扩链,并加入甲基四氢苯酐制备了环氧/酰亚胺/酸酐无溶剂浸渍树脂。树脂的固化工艺由差示扫描量热(DSC)结果确定,用热失重法(TG)对固化树脂耐热性进行评价。以体系在60℃温度下放置96h的黏度变化表征浸渍树脂的储存性。结果表明,酸酐的加入改善了树脂工艺性和储存性,酰亚胺基团的加入使固化树脂具有较好的耐热性。An epoxy resin was chain extended with carboxyl-containing imide, mixed with MeTHPA, an epoxy/imide/anhydride solventless impregnating resin was prepare＆ The curing technology of the resin was determined using differential scanning calorimetry and the heat resistance of the resin was＇characterized using thermogravimetric analysis. The storage stability was evaluated through the viscosity change after stored 96 hours at 60 ℃. It was found that anhydride improved the processability and storage stability, and imide enhanced the heat stability.
