The effect of aging on resin composition was investigated as a part of a study concerned with the evaluation of epoxies containing N , N , N ′, N ′‐tetraglycidyl‐4,4′‐diaminodiphenylmethane (TGDDM). Long‐term stability of three different epoxy resins based on TGDDM and their mixtures with 4,4′‐diaminodiphenylsulfone (DDS) was followed at 23 ± 2°C at a relative humidity ranging from 45% to 55%, by means of GPC and HPLC; short‐term stability of the resins was evaluated at 125°C.
