摘要: 以二苯甲烷双马来酰亚胺与二烯丙基双酚A 为共聚单体, 在适当的催化剂等作用下, 制备了一种改性双马来酰亚胺共聚树脂。对这种改性双马来酰亚胺共聚树脂的溶解性能、固化反应机理和固化反应动力学进行了研究。对这种树脂固化物及其玻璃纤维增强的复合材料力学、电气和耐热性能也进行了研究。Abstract: A modified bismaleimide resin has been obtained by copolymerization of bis(4 maleimido phenyl)methant and o,o ' diallylbisphenol A with suitable catalyzer. This paper deals with the solubility, curing kinetic and mechanism of the resin system, as well as mechanical, electrical, and thermal stability properties of the cured resin matrix and unidirectional glass fiber composites.
