Synthesis, curing, and physical/mechanical properties of 4,4’-bismaleimidodiphenylmethane (BDM), 4,4’-bismaleimidodiphenylether (BDE), 3,3’-bismaleimidodiphenylsulfone (3-BDS), and 4,4’-bismaleimidodiphenylsulfone (4-BDS) adducted with various amount of allylamines were investigated and compared with each other. BDM was reacted with allylamines exclusively through the Michael addition reaction, whereas 3-BDS and 4-BDS were reacted with allylamines by amidation along with the cleavage of an imide-ring C-N bond. Only BDE underwent both reactions to yield BDE/allylamine adducts. Three types of curing reactions might occur depending on the amount of adducted allylamines : (1) thermal homopolymerization through the maleimide double bonds; (2) accelerated homopolymerization by allylamines; and (3) polymerization of the cleaved allylamines by themselves or with the maleimido groups. Of all the BMIs/allylamines adducts under study, the cured BDM/50 mol% allylamine and BDE/50 mol% allylamine adducts have superior mechanical properties. In addition, the former resin has a glass transition temperature (T-g) of 335 degrees C and a degradation temperature (T-d) of 471 degrees C, whereas the latter has a T-g of 349 degrees C and a T-d of 436 degrees C.
