| 摘 要： | 对多单体甲基丙烯酸甲酯（MMA）和苯乙烯（St）熔融接枝无规聚丙烯（APP）进行了研究．实验表明：St的加入不仅可以显著提高MMA的接枝率和接枝物的热稳定性而且可减少APP的降解．通过对不同时段的熔融接枝APP产物进行分析，推断其反应机理为：St首先接枝到APP上，形成稳定的苯乙烯大分子自由基，然后再与MMA发生嵌段反应．

| Abstract: | The multi monomer of methyl methacrylate(MMA)/styrene(St) melt grafting onto atactic polypropylene(APP) was studied.The result showed that the addition of St to the melt-grafting system as a comonomer not only could greatly improve the degree of MMA graft onto APP and enhance the thermally stable of the melt-grafting production,but also could reduce the degradation of APP.Through the analysis of the melt-grafting production which is obtained in different time,we can conclude the mechanism is: the St graft o... |
