Description

Using N, N′-4, 4′-diphenylmethane-bismaleimide (BMI), 4, 4′-diaminodiphenylmethane (DDM) and o, o′-diallyl-bisphenol A, detailed investigation was conducted on the influences of curing method and chain extension reaction (related to molar ratio) on the mechanical properties of amine-modified or allyl-modified maleimide resins.<BR>On the effect of curing conditions, the more uniformly cured structure was obtained by “stepwise curing by raising temperature” than “isothermal curing at a high temperature”.<BR>In both BMI/DDM and BMI/CA systems, lowering molar ratio (by increasing chain extension reaction, for example) made glass transition temperature (Tg) lower, and gave improved deflection at break and fracture toughness (G1c). In BMI/CA system, however the improvement was not so effective as BMI/DDM system because of formation of the rigid ring structure through Diels-Alder” reactions with “ene”.<BR>From these results, the relationship between the mechanical properties and the structure of cured resins was considered.
