摘要:

本文介紹了含二氮雜萘酮聯(lián)苯結(jié)構(gòu)聚芳醚系列樹脂和烯丙基雙酚A（DABPA）、對二苯甲烷型雙馬來酰亞胺（BDM）樹脂共混增韌改性研究進展。以耐高溫可溶性含二氮雜萘酮聯(lián)苯結(jié)構(gòu)聚芳醚酮（PPEK）、聚芳醚砜（PPES）或聚芳醚腈酮（PPENK）為增韌改性劑，既可以提高BMI共混物的韌性，又賦予其優(yōu)異的耐熱性能，相比而言，含砜基的PPES的增韌效果最好。分別對聚芳醚進行氨基和馬來酰亞胺基封端改性，并將其用于BDM的共混改性，結(jié)果表明氨基和馬來酰亞胺端基均參與BDM樹脂的固化反應，增強了聚芳醚樹脂與BDM樹脂的界面粘結(jié)作用，進而提高增韌效果，其中，加入馬來酰亞胺封端PPES的增韌效果最好，缺口沖擊強度比純BDM樹脂提高近1倍，達到4.26 kJ／m2，樣品斷面形貌結(jié)構(gòu)分析表明共混物發(fā)生了明顯塑性變形，在斷裂過程中吸收了大量的沖擊能，從而使韌性提高。

Abstract:

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 solfone 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 showed 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 have 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.
