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.
