摘　　要：采用溶液及微乳液两种聚合法,合成苯乙烯-N-苯基马来酰亚胺-马来酸酐(St-NPMI-MAH)三元共聚物。通过IR,1HNMR,13CNMR,GPC表征共聚物结构,溶液聚合产物为嵌段共聚物,乳液聚合产物为无规共聚物。采用DSC、TGA研究共聚物的热性能,溶液聚合产物的玻璃转化温度为212.9℃,5%热失重温度为348℃;微乳液聚合产物的玻璃转化温度为214.4℃,5%热失重温度为374℃。Styrene-N-Phenylmaleimide-Maleic Anhydride Tercopolymers were synthesized by the method of solution polymerization and microemulsion polymerization. The structures of copolymers were characterized by IR, 1HNMR, 13CNMR and GPC. Results showed that the product of solution and microemulsion polymerization were block and random copolymer. The heat resistance and thermal stability were investigated by DSC. TGA, the glass transition temperature and the thermal decomposition temperature （5 % mass loss） of solution polymerization product were 212.9℃ and 348 ℃, 214.4℃ and 374 ℃ for microemulsion polymerization product.
