Science and Research Department, Shijiazhuang University, Shijiazhuang 050035) Abstr act Mechanical and flaming properties of flameretardancehigh impact polystyrenemodified by S Sor EPDM were studied. The results showed that comprehensive properties of composite of containing S S were better than those of containing EPDM;impact strength of composite was increased with S S amount being raised; when S Samount was 12%, 2 2 impact strength of composite about reached 9kJ/ m ,which about increased 7kJ/ m on the base of former impact strength; flame retardance properties of composite of containing S S were not influenced.
