γ射线辐照聚丙烯接枝改性研究

Study on Graft Modification of γ-radiated Polypropylene

采用γ预辐射熔融接枝极性单体,对改性聚丙烯(PP)进行机械性能和应用性能方面的研究。实验证明,在PP分子接枝极性单体后,可以明显提高PP极性,且可以改善PP复合、印刷性能。

γ-pre-radiated polypropylene was melt-grafted by polar monomer. The mechanical performance and application performance of the modified polypropylene was studied. It was showed that the polarity significantly increased; the compound and printing performance were improved after polypropylene molecules grafting the polar monomer.
