摘要
研究了(NH_4)_2S_2O_8-CO(NH_2)_2新氧化还原体系引发丙烯酸甲酯、明胶接枝共聚,讨论了各反应参数如聚合温度、引发剂浓度、单体浓度、主链浓度及反应时间对接枝率、接枝效率、总转化率的影响。测定了接枝聚合物粘度及支链分子量。
The graft copolymerization of methyl acrylate and gelatin using the new persulfate-urea-redox system is studied. The effects of experimental param eters such as copolymerization temperature, concentration of initiator、monomer and backbone; the reaction time on the percentage and efficiency of grafting and the total yield is also discussed. The work was also carried out to study PMA branch molecular weight and its intrinsic viscosity.
