摘要: 应用ESCA研究辐射接枝共聚物的文章已有报道。然而,有关聚苯乙烯-丙烯酸辐射接枝共聚物的表征工作报导甚少。本文用X-光电子能谱(XPS)研究了聚苯乙烯-丙烯酸辐射接枝共聚物,并通过不同环境碳不同位置的峰面积之比表征接枝率。

Abstract: Radiation graft copolymer of polystyrene -g- acrylic acid has been characterized by XPS. It is found that along with the main peak C1S there is a photoelectron peak at 289.0eV that appears to be C1S of group and shows the presence of polyacrylic acid grafted on the polystyrene. The graft level obtained by XPS method is consistent with that from gravimetric method.
