摘　　要：利用双螺杆挤出机制备了聚碳酸酯/甲基丙烯酸甲酯-丁二烯-苯乙烯(PC/MBS)共混合金,研究了常温和低温条件下MBS含量对该合金力学性能的影响,并重点考察了PC/MBS合金的流动性能和流变性能。结果表明:MBS的添加对PC具有明显的增韧作用,并且有效提高了PC/MBS合金的熔体流动速率(MFR),使材料的加工性能显著改善。另外,当MBS含量为15%时,PC/MBS合金的流变性能最佳。The polycarbonate/methylmethacrylate-butadiene-styrene（PC/MBS） alloys were prepared by a twin-screw extruder. The effect of MBS content on mechanical properties of PC/MBS alloys was studied under normal and low temperatures, and rheological and flow properties of PC/MBS alloys were investigated also. The results show that MBS has favorable toughening effect on PC. The melt flow rate（MFR） of the PC/MBS alloys increases significantly with the addition of MBS, and the alloys show good processing properties. While the MBS content increases to 15%, the PC/MBS alloy has the best rheological behavior.
