摘要
本文应用示差扫描量热 (DSC)法对间苯二胺 (MPDA)和二氨基二苯甲烷 (DDM)混合物进行了等速升温熔融研究，得出了它们的最低共熔配比；通过凝胶化时间测定，得出了它们固化环氧树脂的反应活化能，并从它们的化学结构入手，指出了此种物理改性的不足，结合机械性能的测试，指出了二氨基二苯甲烷作为环氧树脂韧性固化剂的应用前景。
In this paper, the DSC analysis is used to study the MPDA/DDM mixture, the lowest co－ melting temperature and ratio are given; by the measurement of gel－ times, the curing reaction activation energies are derived, and it is stated that DDM can be used as high－ toughness curing agent of epoxy resin through the analysis of its chemical structure and the properties of its epoxy resin curing compound.
