    摘要： 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.
