THERMOPLASTIC COMPOSITION HAVING HIGH IMPACT-RESISTANCE

摘要

PURPOSE: A thermoplastic resin composition having good impact-resistance is provided to have improved impact-resistance and fluidity by using modified ethylene-propylene rubber containing epoxy group as a compatibilizer. CONSTITUTION: A thermoplastic resin composition includes 20-80 weight parts of polycarbonate resin and 80-20 weight parts of polypropylene resin. The composition also contains 1-10 weight parts of modified ethylene-propylene rubber having epoxy group, as a compatibilizer for two resins, based on total 100 weight parts of the resins. Additionally, the composition is added by 0.1-0.5 weight parts of a reaction catalyst, that is quaternary ammonium salt. The quaternary ammonium salt can be a benzyltrimethyl ammonium chloride or tetrabutylammonium iodide.
