Meanwhileby adding 12-bis(pentabromophenyl)ethane(DBDPE) to the masterbatchhigh heat resistant and fl ame retardant ABS was fabricated by twin-screw extruder at 180–210 . The results show that the fabricated high heat resistant and fl ame retardant ABS material both features high heat resistance and fl ame retardancy, at the same time, the heat resistance and its content have a positive correlation by this two-step method. Meanwhile, with the DBDPE the masterbatch hea
