| 摘 要： | 用在50L固相接枝反应器中合成的马来酸酐接枝聚丙烯(PP-g-MAH)作界面改性剂，制备了马来酸酐接枝聚丙烯／聚丙烯／碳酸钙(i-PP／PP-g-MAH／CaCO3)复合材料。研究了i-PP／PP-g-MAH／CaCO3复合材料的力学性能和增容机理。结果表明，PP-g-MAH对i-PP／CaCO3复合物的缺口冲击强度、弯曲强度和拉伸强度均有提高；PP-g-MAH与CaCO3反应形成PP-g-MAH的钙盐，实现反应性增容。

| Abstract: | Polypropylene/calcium carbonate composites (i-PP/CaCO_3) were prepared with isotactic polypropylene-maleic anhydride graft copolymer as interfacial modifier,in which PP-g-MAH was synthesized by means of solid phase graft copolymerization in a 50 L reactor. The mechanical properties and compatibilizing mechanism of the composite were studied. The results showed that the use of PP-g-MAH improved the notched impact strength,bending strength and tensile strength of the composite,and PP-g-MAH reacted with CaCO_3,resulted in reactive compatibilization. |
