Toughening bismaleimide resins by N-allyl aromatic amine

Abstract

N'N′-Diallylaminodiphenyl methane, coded as ADM, was prepared and used to modify 4,4′-bismale-imidediphenyl methane (BDM). Copolymers of BDM and ADM, and composite based on the copolymer were prepared and characterized. Results show that the copolymers and composite have good thermal and mechanical properties as well as hot/wet resistance after postcured at 200°C for 6h.
