摘　　要：采用半间歇悬浮聚合法合成了只表现出单一玻璃化转变温度(T_g)的苯乙烯-N-苯基马来酰亚胺共聚物(SMI),讨论了影响聚合反应的主要因素。当反应温度为60～75℃,活性磷酸钙为悬浮剂,单体苯乙烯的配比为45～75时,用半间歇悬浮聚合法合成了组成均一、只表现出1个T_g的SMI,其收率可达99%以上。The binary copolymer of styrene and N-phenyl rnaleimide (SMI) having a single glass transition temperature (Tg) was synthesized by semi-batch suspension polymerization. The key factors affecting the polymerization reaction was discussed. A grade of SMI copolymer possessing homogeneous composition and a single Tg was prepared at a temperature in the range of 60 to 75℃ under the conditions of using active calcium phosphate as suspending agent and adding 45%-75%(wt) styrene monomer.The reaction yield reached above 99%.
