本发明涉及由亚甲基桥连的聚(环脂族-芳族)胺混合物固化的改进聚环氧化合物树脂和一种制备这种聚环氧化合物树脂的方法，还涉及亚甲基桥连的聚(环脂族-芳族)胺组合物和其一种制备方法。改进在于使用的固化剂(此处称作"重MPCA")包含甲醛和苯胺或甲基取代苯胺的部分氢化的缩合产物，所述苯胺或甲基取代苯胺包含较大量(35-85wt％，优选40-60wt％)的3，4，5，6，7，8，9，10，11，12，13，14和15个苯胺或甲基取代的苯胺衍生物形式的低聚物。 This invention relates to improved polyepoxide resins cured with a mixture of methylene bridged poly(cycloaliphatic-aromatic)amines and a process for preparing such polyepoxide resins as well as to the methylene bridged poly(cycloaliphatic-aromatic)amine compositions and a method of making them. The improvement resides in using a curative (herein referred to as "Heavy MPCA") comprised of the partially hydrogenated condensation product of formaldehyde and aniline or methyl substituted aniline containing a substantial amount (from 35 to 85% by weight, preferably 40 to 60% by weight) of oligomers in the form of 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15 aniline or methyl substituted aniline derivatives.
