Abstract: The present invention provides an olefin resin (β) satisfying the following requirements (I) to (VI), and a propylene resin composition including the same. (I) (β) includes a grafted olefin polymer [R1] containing a main chain composed of an ethylene/α-olefin copolymer and a side chain composed of a propylene polymer. (II) The ratio P wt % of the amount of the propylene polymer contained in (β) is from 5 to 60 wt %. (III) When the ratio of the amount of a component(s) having a peak temperature of a differential elution curve as measured by cross-fractionation chromatography (CFC) using o-dichlorobenzene as a solvent of less than 65° C., to the amount of (β) is taken as E wt %, the value a represented by the following equation (Eq-1), in relation to the ratio E and the ratio P, is 1.4 or more. (IV) The melting point (Tm) and the glass transition temperature (Tg), as measured by differential scanning calorimetry (DSC), are from 120 to 165° C. and from −80 to −30° C., respectively. (V) The hot xylene-insoluble content is less than 3 wt %. (VI) The limiting viscosity [η] as measured in decalin at 135° C. is from 0.5 to 5.0 dl/g. a=(100−E)/P  (Eq-1)

Abstract: An object of the present invention is to provide a propylene-based resin composition capable of providing a molded article having an excellent balance between rigidity and impact resistance. The object can be achieved by a propylene-based resin composition including an olefin-based resin characterized by including a grafted ethylene-based copolymer having an ethylene polymer as a side chain.
