SYNDIOTACTIC POLYSTYRENE COMPOSITIONS HAVING IMPROVED IMPACT STRENGTH

摘要

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.
