| Summary: | 碩士 === 國立臺北科技大學 === 有機高分子研究所 === 101 === This study investigated the toughness improvement of recycled polycarbonate (RPC) by mixing with the core-shell rubber impact modifier (CSR). The test samples were melt- extruded via a twin screw extruder connected with an injection process. The Styrene Maleic Anhydride Copolymer (SMA) was used as the impact modifier. The morphology of fractured surfaces and the structure of the samples were examined by employing the Scanning Electron Microscope (SEM). The izod impact， tensile strength and flexural strength have also been studied by a universal testing machine. The Experimental results show that impact modifier can efficiently improve the mechanical properties of the recycled polycarbonate; however, excessive addition of CSR may cause the decaying of notched impact strength. The optimal condition of the toughness for the PC/CSR blends was 97/3 wt. %.
