摘　　要：利用双螺杆挤出机制备PC/ASA合金,探讨了不同PC与ASA配比对性能的影响。结果表明:在PC/ASA体系中,PC与ASA的配比为70∶30,添加4%的相容剂SMA以及0.8%的抗氧剂、润滑剂,能获得最优的性能:悬臂梁缺口冲击强度达66.7k J/m^2,拉伸强度达56.1MPa,弯曲强度达82.3MPa,热变形温度达105.6℃;同时比同等条件下制备出来的PC/ABS合金拥有更好的耐光性。Using a twin-screw extruder equipment, PC/ASA alloy was prepared, the effects of different ratio of PC and ASA on performance were investigated. The results showed that：in PC/ASA system, PC and ASA ratio is 70 ： 30, adding compatibility agent SMA 4% and 0. 8% of antioxidant and lubricant, can achieve optimal perform- ance：Izod notched impact strength of 66.7kJ/m2, the tensile strength of 56. 1MPa, the bending strength of 82. 3MPa, heat distortion temperature of 105.6℃ ;while PC/ABS was prepared under the same conditions, PC/ASA alloy has better lightfastness than PC/ABS.
