摘　　要：通过乳液共聚合的方法合成了 N-苯基马来酰亚胺 (N- PMI) /甲基丙烯酸甲酯 (MMA) /丙烯腈(AN)三元共聚物 ,用 DSC、TBA及 TGA热分析方法对共聚物的热性能进行了对比表征 ,实验结果表明 ,TBA能更好地表征 N- PMI对共聚物耐热性能的影响 ,从 TGA结果看 ,加入 N- PMI可以有效地提高材料的热分解温度。同时用 GPC对共聚物的平均分子量及其分布进行了表征。There has been a considerable interest in the synthesis of copolymers containing maleimide moieties especially of PMI. Such copolymers contain five -member planar rings in the chain, which hinder chain rotation, resulting in greater structural stiffness and higher thermal stability. Recently, emulsion copolymerization of N-aryl-substituted maleimide and other vinyl monomers, such as styrene, were investigated, aiming at structure-controlled copolymers. In this work, terpolymers of N-phenylmaleimide (PMI). methyl methacrylate (MMA) and acrylonitrile (AN) were synthesized by emulsion copolymerization method. The mechanical properties and thermal stability were investigated.
