Notes:
Nanocomposites of nanosized-CaCO3/polypropylene-ethylene copolymer (PPE) and nanosizedCaCO3/ PPE/ styrene-butadiene-styrene (SBS) were prepared by using two-roll mill and singlescrew extruder. The average particle size of nanosized CaCO3 was determined to be about 30 nm.By adding nanosized CaCO3 into PPE matrix, the toughness of the matrix improves significantly. Atnanosized CaCO3 content of 12 phr (parts per hundred PPE resin by weight), the impact strength ofCaCO3/PPE at room temperature reaches 61.6 KJ/m2, which is 3.02 times that of unfilled PPEmatrix. In addition, the synergistic toughening effect of nanosized CaCO3 and SBS particles on PPEmatrix was investigated
