摘　　要：采用异步合成法制备了氰酸酯树脂(CE)/聚甲基丙烯酸甲酯(PMMA)、CE/聚苯乙烯(PS)及CE/聚丙烯腈(PAN)共聚物,对比了3种热塑性树脂对共聚物力学性能、玻璃化转变温度及转化率的影响,并以CE/PMMA为例讨论了共聚物的相图变化、微观结构与宏观性能之间的联系及PMMA含量、催化剂和固化温度对体系相结构的影响。结果表明,改性后共聚物在多个方面都表现出优于本体聚合材料的性能。PMMA/CE, PS/CE and PAN/CE copelymers were prepared by means of asynchronous synthesis. The effects of three kinds of thermoplastics on the mechanical properties, glass - transition temperature and conversion rate of the copelymers were discussed respectively. The phase diagram, the relation between microstructure and macroscopical properties of the copelymers and the effects of PMMA content, catalyst and curing temperature on the phase structures were discussed with CE/PMMA as example. The resuits showed that after modification, the copolymers excelled the bulk polymer in many properties.
