【摘要】 <正>聚丙烯（PP）接枝顺丁烯二酸酐（MAH）有着强烈的应用程序背景,已经倍受人们关注。许多重要的研究结果已经在过去几年内得到充分的应用。然而,要获得分子水平上接枝信息仍然十分困难,用 MAH 接枝 PP 精确的机理和接枝的 PP 结构不是完全清楚。在本项研究中,用¹³C 富集的顺丁烯二酸酐接枝定向聚合的聚丙烯（iPP）,分别获得接枝物中 MAH 含量为0-5．5wt%样品,溶液 NMR 实验表明,MAH 的接枝聚丙烯效率与摹拟结果相似。更多还原

【Abstract】 The graft of maleic anhydride(MAH)onto polypropylene(PP)has received much attention due to its strong application background.Many important results related to this topic have been achieved in the past decades.However,it is still difficult to obtain the detail information about the grafting at molecular level.The precise grafting mechanism and structures of grafted PP with MAH has not been completely clear.However,the eiTect of initial MAH content on the grafting has not been studied in experiment up to now.更多还原
