Abstract: HIPS has been grafted by maleic anhydride in the presence of dicumyl peroxide. The influences of the reaction time and the feed ratio of the reactants on the graft rate have been examined. The IR spectra revealed the grafting. As to the dynamic mechanical property of the HIPS-g-MA, two new damping peaks at 29℃ and 52℃ were observed on its tanδ-T curve.
