中文摘要：
采用2步法工艺制备了PP／POE／BaSO4[聚丙烯／（乙烯／辛烯共聚物）／硫酸钡]、PP／POE／偶联剂处理BaSO4和PP／POE／马来酸酐处理BaSO4三元复合体系。前2种三元复合体系形成了完全分离结构，而后1种三元复合体系形成了核壳包覆结构。力学性能研究表明，具有核-壳结构的三元复合体系的拉伸屈服应力、冲击韧性大于具有完全分离结构的三元复合体系，但前者的弯曲模量与断裂伸长率小于后者。
英文摘要：
PP/POE/BaSO4, PP/POE/BaSO4 treated by coupling agent, PP/POE/BaSO4 treated by MAH were prepared by new two step process. The two formers ternary composites were separated completely in morphology, the later was formed in core-shell inclusions. Mechanical properties investigation indicates that the yield strength and impact tougheness of composite with core-shell morphology are higher than those of composites with separated morphology, but the former has lower flexural modulus and elongation at break than the latter.
