Popis:	Polypropylene /calcium carbonate-maleic anhydride-polypropylene wax(PP /CaCO3-MAH-PPW) composites were prepared by means of in situ solid phase graft copolymerization using MAH and PPW as the main raw materials.Compared with PP/PP-g-MAH/CaCO3 composites using MAH grafted with PP(PP-gMAH) as compatibilizer,PP/CaCO3-MAH-PPW composites exhibit higher impact resistance,bending and processing properties.The results show that a good dispersion of calcium carbonate and an appropriate interface bonding between CaCO3 and PP are the key factors in order to obtain the composite with good toughness.When m(PP) ∶ m(CaCO3) = 100 ∶ 20,the notched impact strength of PP/CaCO3-MAH-PPW composite reaches a maximum,which is 1.19 times as high as that of the matrix resin.
