Graft copolymerization of methacrylic acid (MAA) onto SBS powder was studied by ,60,Co γ-ray irradiation. Effects of the irradiation dose, MAA concentration, and irradiation conditions on the graft yield were studied. The graft copolymer, SBS-g-MAA, was characterized by means of Fourier-transform infrared (FT-IR) spectroscopy, gel permeation chromatography (GPC), scanning electron microscopy (SEM), differential scanning calorimetry (DSC) and dynamic shear rheological (DSR). The -C=O- absorption peak at 1705cm,-1, of the FT-IR spectra, and the wilder molecule number distribution of SBS-g-MAA by GPC analysis indicated that the MAA monomer had been grafted onto SBS molecular chains. The DSC analysis revealed an increased glass transition temperature of PS phase of the grafted SBS, while the DSR showed of the MAA monomer affected the PS phase of SBS more easily.
