摘要: 采用马来酸酐、二甲基丙烯酸乙二醇酯、三羟甲基丙烷三基丙烯酸酯对聚丙烯进行改性。以自由基反应机理为基础,讨论了引发剂用量、反应时间、改性试剂的种类、用量等因素对改性PP凝胶含量及性能的影响,提出了力学性能的优选条件。得到了力学性能优良的改性PP,为其进一步功能化提供了理论参考。Abstract: he modification of polypropylene has been performed by solution grafting of maleic anhydride,ethylene glycol dimethyl acrylate and trimethylol propane trimethyl acrylate. The effects of initiator concentration, reaction time and different kinds of modifie
