摘　要：将胺化聚碳酸酯（a-PC）和环氧树脂（EP）以一定比例混合，加热到120～160℃后加入熔化的二氨基二苯基甲烷，可制备固化的胺化聚碳酸酯增韧环氧树脂。结果表明，EP与a-PC形成了网络结构,且当a-PC质量分数为10％时，试样断裂韧性最大。

Abstract：The morphology and properties of epoxy resin toughened by amino- polycarbonate were studied. The morphology, glass transition behavior and properties of EP/amino- PC system indicated that amino- polycarbonate was miscible with the epoxy resin matrix and the systems had a single glass transition temperature. The optimum toughened properties were achieved when the content of amino- polycarbonate was about 10 phr.
