摘要：

This paper describes the effect of diglycidyl ether of bisphenol A (DGEBA) on the curing behaviour of a chain-extended bismaleimide resin. 4,4'-Bismaleimidophenyl sulfone (BS) resin was treated with 4,4'-diaminodiphenyl ether or 4,4'-diaminodiphenyl methane to yield BS-M and BS-E resins which were then solution-blended with DGEBA containing stoichiometric amounts of amine as hardener. A decrease in the curing temperature of BS-M or BS-E was observed on blending with DGEBA. The thermal stability of the cured resin was reduced on blending. © 1990.
