Abstract

The syndiotactic polystirene resin composition according to the present invention is superior in compatibility between a syndiotactic polystyrene and a rubber component and mechanical properties such as impact strength, in which a syndiotactic polystyrene-maleic anhydride (sPS-MA) and a hydrogenated styrene/butadiene/styrene-maleic anhydride (SEBS-MA) are employed as compatibilizers and a diamine compound is added as a coupling agent. The compatibilizers and coupling agents improve polarity of both the syndiotactic polystyrene and the rubber component and impact strength of the syndiotactic polystyrene composition.
