双马来酰亚胺与酚醛树脂二元共聚物的研究

Study on bismaleimide and allyl ether phenolic resin binary copolymers

本文合成了双马来酰亚胺和烯丙基醚化酚醛树脂的二元共聚物,并利用红外光谱(FT-IR)对共聚物的结构进行表征,利用TGA测试手段对共聚物的热学性能进行测试,结果表明,共聚物的热性能与纯酚醛树脂相比得到不同程度地提高,而液晶双马来酰亚胺共聚物体系较二苯甲烷型双马来酰亚胺共聚物体系具有更好的耐热性.

Bismaleimide and allyl ether phenolic resin binary copolymers were prepared by solution copolymerization, The chemical structure of eopolymers were confirmed by FT- IR the thermal properties were examinated by TGA. The results show that the modified resins by bismaleimide, especially by liquid crystal bismaleimide, have higher temperature resistance.
