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 onto APP first, and form the stable styryl macroradicals, then MMA block onto the styryl macroradicals.
