Abstract
Propylene-based resin compositions contain an inorganic filler in a high ratio and are excellent in flexibility, mechanical strength, elongation at break, heat resistance, scratch resistance, whitening resistance and flame retardancy. Shaped articles comprise the compositions. A first propylene-based resin composition of the present invention contains 5 to 64.9% by weight of a propylene-based polymer (A) having a melting point, as measured by differential scanning calorimetry (DSC), in the range of 120° C. to 170° C.; 0 to 59.9% by weight of a propylene-based polymer (B) having a melting point, as measured by differential scanning calorimetry (DSC), of less than 120° C. or having no observed melting point; 0.1 to 30% by weight of a graft-modified propylene-based polymer (C) obtained by graft modifying a propylene-based polymer having a melting point, as measured by differential scanning calorimetry (DSC), of less than 120° C. or having no observed melting point; and 35 to 75% by weight of an inorganic filler (D) (here, the total amount of (A), (B), (C) and (D) is 100% by weight).
