【摘要】 采用N-(4-羟基苯基)马来酰亚胺与苯乙烯为单体,以四氢呋喃为溶剂,偶氮二异丁腈为引发剂,加入RAFT试剂二硫代苯甲酸苄酯进行RAFT聚合,成功地得到N-(4-羟基苯基)马来酰亚胺和苯乙烯相对分子质量分布较窄的共聚物,单体转化率基本随聚合反应时间而呈线性增加,且该聚合物的耐热性能也有所提高.更多还原

【Abstract】 N-(4-hydroxyphenyl) maleimide is a widely used organic compound intermediate.The special functional groups play an important role in the polymer modification.In this paper,the RAFT polymerization was developed by taking N-(4-hydroxyphenyl) maleimide and styrene as the monomers,tetrahydrofuran and ethanol as the solvent,azobisisobutyronitrile as the initiator,and S-benzyl dithiobenzoate as the RAFT reagent.Results have shown that the copolymer of N-(4-hydroxyphenyl) maleimide and styrene with narrow polydispersities is produced,and the thermomechanical property of the polymer is improved.更多还原
