摘　　要：采用由苯乙烯(St)、马来酸酐(MAH)和丙烯酸丁酯(BA)组成的三元聚合物P(St/MAH/BA)作为纳米CaCO_3的表面改性剂,制备了纳米CaCO_3/PS复合材料,并对复合材料的力学性能进行了测试。结果表明,P(St/MAH/BA)作为纳米CaCO_3表面改性剂与PS的相容剂能够明显改善纳米CaCO_3/PS复合材料的力学性能,经P(St/MAH/BA)改性的纳米CaCO_3对PS具有明显的增韧改性作用。Terpolymer P（St/MAH/BA）, synthesized by styrene （St）, maleic anhydride （MAH） and butyl acrylate （BA）, was used as the surface modifier of nano-CaCO3. Nano- CaCO3/PS composite materials were prepared. The mechanical properties of nano-CaCO3/PS composite materials were investigated. The results show that the mechanical properties of nano-CaCO3/PS composite materials are obviously improved when P （St/MAH/BA） is simultaneously used as surface modifier of nano-CaCO3 and compatibilizer of PS, nano-CaCO3 modified by P（St/MAH/BA） can toughen and modify PS.
