摘　　要：通过FT-IR和DSC等对N,N-4,4’-二苯甲烷型双马来酰亚胺树脂(BMI)、双酚A型氰酸酯(BADCy)和聚芳醚砜(PES-C)的共固化反应进行研究。结果表明,固化过程前期的主反应是氰酸酯和双马来酰亚胺的自聚反应,固化反应进行2h以后,氰酸酯和双马来酰亚胺共聚反应成为主反应。动力学研究确定了树脂固化反应的活化能(Ea=70.765kJ·mol^-1),频率因子(lnA=16.6)和反应级数(n=0.923)。并根据动力学数据确定了树脂的固化条件。The co-curing reactions of a bismaleimide(N,N-4,4’-bismaleimidediphenylmethane,BMI)associated with a bisphenol A dicyanater(BADCy)and with a polyaryl ether sulfone(PES-C)are investigated by the FTIR and DSC.The results show that in the early stage,the cyanate ester and bismaleimide is curing independently,2 hours later,the copolymerization reaction between the cyanate ester and bismaleimide becomes the main reaction.The activation energy(Ea=70.765kJ·mol),frequency factor(lnA=16.6)and order of reaction(n=0.923)has been determined by the kinetic study.Finally,the conditions of resin curing are confirmed by the kinetic data.
