The influence of the compounding route of polypropylene (PP)/ethylene-propylene- diene terpolymer (EPDM)/nano-CaCO3 composites on their properties; including their mechanical properties; the dispersion degree of nano-CaCO3; and the morphology of EPDM; was studied. The results showed that the toughness of the composites and the morphology of the EPDM particles were markedly influenced by the compounding route; whereas the dispersion degree of nano-CaCO3 in the matrix was little influenced by the compounding route. The impact strength of composites prepared by one route was about 60 kj/m2 with 20 wt % nano-CaCO 3. The results indicated that a sandbag of nano-CaCO3 embedded in EPDM could effectively improve the toughness of the composites. A sandbag composed of EPDM and nano-CaCO3 eliminated the deterioration effect of the nano-CaCO3 agglomerate on the toughness of the composites; whereas the nano-CaCO3 agglomerate separately dispersed in PP decreased the toughness of the tercomponent composite © 2005 Wiley Periodicals; Inc;
