摘　　要：研究了马来酸酐接枝聚丙烯(PP-g-MA)对聚丙烯(PP)/碳酸钙(CaCO3)共混体系力学性能的影响。结果表明:PP-g-MA对PP/CaCO3共混体系有增容改性作用,当加入5%的PP-g-MA时,该复合材料的冲击强度和拉伸强度均有显著提高。The effect of the content of maleic anhydride grafted polypropylene(PP-g-MA) on the mechanical property of the composites(PP/ CaCO3) is investigated.The experimental results show that PP-g-MA will improve the compatibility of PP and CaCO3.When the content of PP-g-MA is 5%,both the notched impact strength and tensile strength of the composites increase greatly.
