摘　　要：利用乳液共聚合的方法制备了苯乙烯(St)、丙烯酸乙酯(EA)、N-苯基马来酰亚胺(NPMI)共聚物,并考察了单体配比和引发剂浓度对产物性能的影响。采用FT-IR、GPC、TGA等方法对其组成和性能进行了表征。结果表明:该三元共聚物具有良好的耐热性能,玻璃化温度和热稳定性随共聚物中NPMI含量的增加而提高,将是一种具有广阔开发前景的耐热改性剂。Copolymers of styrene（St）,N-phenylmaleimide（N-PMI） and Ethyl acrylate（EA） were synthesized by emulsion tri-polymerization.The effects of monomers ratio and initiator concentration on the copolymers were investigated.The composition and performance of the copolymers were characterized by FT-IR,GPC,and TGA.The results showed that the copolymers had good thermal properties and glass transition temperature as a promising heat-resistant modifer,and the thermal stability of copolymers aslo enhenced with the increasing content of N-PMI.
