摘要 合成大分子单体的封端剂一般是含卤素原子的烯烃化合物、丙烯酰卤化合物、卤代环氧化合物及不饱和酸酐等四大类。甲基丙烯酸环氧丙酯(GMA)作为聚苯乙烯(PS)活性阴离子封端剂合成甲基丙烯酸环氧丙酯封端聚苯乙烯大分子单体(PS-GMA) Macromers are the living polymers both of narrow-dispersed and in copolymerization with other monomers. The molecular weight and molecular-weight distribution (NWD) of their macromolecules and grafting efficiency were determined by high performance gel permeation chromatography (HPGPC). It was certainly found that the macromers obtained under optimum conditions were highly active in the copolymerization with butyl acrylate by HPGPC.
