摘　　要：采用过硫酸铵 -尿素新氧化还原体系研究了丙烯酸丁酯与明胶的接枝共聚 ,分析了共聚参数对接枝率、接枝效率、总转化率的影响 ,讨论了此体系下的接枝共聚机理。The graft copolymerization of butyl acrylate and gelatin was studied by using the new persulfate-urea system. The effects of experimental parameters such as copolymerization temperature,concentration of initiator,monomer ,backbone,the time on the grafting percentage and grafting efficiency and the total yield were discussed. The mechanism of graft polymerization based on this initiating system was also investigated.
