Abstract
A detailed investigation on the curing reaction of maleimide resin in the presence of epoxy resin was conducted using model compounds. Selecting N-phenylmaleimide (PMI), phenyl glycidyl ether (PGE), N, N'-diphenylaspartimide (API) and aniline (AN) as model compounds, the reactions of PMI/PGE/API, PMI/PGE/AN systems were investigated. Without catalyst, the main reaction was the addition reaction of AN to PGE and PMI reacted a little. In 2-ethyl-4-methylimidazole (2E4MZ) catalyst system, the main reactions were the polymerization of PMI and the addition reaction of AN to PGE. When epoxy resin existed, the polymerization reaction of PMI was accelerated.
