摘要：This paper introduces the progress on the studies of BMI blends modified by poly(aryl ether)s containing phthalazinone moieties and o, o'-diallyl bisphenol A (DABPA). The toughness and thermal properties of BMI blends can be both improved by introducing heat-resistant poly(phthalazinone ether ketone) (PPEK), poly(phthalazinone ether sulfone) (PPES) or poly(phthalazinone ether nitrile ketone) (PPENK) resins. Comparatively, PPES has the relatively better toughening effect than the other two resins due to the existence of stronger aprotic sulfone groups in the main chains. Moreover, PPEK and PPES end-capped by amino and maleimide groups were also blended with BDM and DABPA as modifiers. The results show that both amino and maleimide groups took part in the curing reaction of BDM, which enhanced the interface bonding effect between thermal plastics and BDM resin. Especially, PPES end-capped by maleimide groups has the best toughening effect among these poly(aryl ether)s. All of these blends experience plastic deformation during the impact test, and poly(aryl ether)s can absorb a large amount of impact energy, thus enhance the toughness of BDM blends. ? 2015, The Editorial Board of Materials China.
