摘    要:采用无溶剂自相溶工艺,将侧链带有烯键的含芴聚芳醚酮(RPFEK)溶解于二烯丙基双酚A(DABPA),低温下加入4,4′-二氨基二苯甲烷双马来酰亚胺(BMDM)进行熔融共聚,再用高温固化的方式制备了带烯键含芴聚芳醚酮增韧的改性双马来酰亚胺(BMDM/DABPA)复合材料。结果表明,这种复合材料是一种互穿交联网络结构,RPFEK的引入不但对复合材料的玻璃化转变温度无明显影响,而且有利于复合材料热稳定性的提高;可反应烯键的引入提高了RPFEK与BMDM树脂的相容性与界面的粘接作用;与纯BMDM/DABPA树脂相比,10 % RPFEK增韧的BMDM/DABPA树脂的冲击强度从9.0 kJ/m2提高到了15.2 kJ/m2。

关 键 词:双马来酰亚胺  二烯丙基双酚A  增韧  带烯键含芴聚芳醚酮

Bismaleimide Resin Toughened by Reactive PFEK with Pendant Propenyl Groups
Abstract:Poly(fluorene ether ketone) (PFEK) with pendant propenyl groups was dissolved in a bismaleimide (BMI) resin composed of 4,4-bismaleimidodiphenyl methane (BMDM) and DABPA without using any solvent. The solution was self-cured at a high temperature forming an interpenetrating network which gave a single endothermic peak on a DSC curve. The glass transition temperature (Tg) of the system did not decrease with the increase of PFEK, which rendered the system a good thermal stability. Compared with neat BMI resin, the impact strength was elevated from 9.0 to 15.2 kJ/m2 by 10 phr PFEK. Scanning electron microscopy (SEM) of fracture surface revealed that the material had a good interfacial adhesion.
Keywords:bismaleimide  diallylbisphenol    A  toughness  reactive poly(arylene ether ketone)
