ABSTRACT OF THE DISCLOSURE A polyolefin composition and the same especially used for producing vehicle exterior members which is excellent in softness, impact resistance, moldability, appearance, restorable property and so forth. The composition comprises 20 to 70% by weight of a crystalline propylene polymer (a); 10 to 50% by weight of a substantially amorphous .alpha.-olefin copolymer (b); 5 to 50% by weight of an ethylene-.alpha.-olefin copolymer (c) which is 0.860 to 0.910 g/cm3 in density, 10% by weight or more in boiling n-hexane insoluble matter and 100°C or higher in the maximum peak temperature Tm according to the differential scanning calorimetry (DSC); and 5 to 30% by weight of an ethylene polymer (d) of 0.910 to 0.965 g/cm3 in density, wherein the total of said components (a), (b), (c) and (d) is 100% by weight. |
