<p>An olefinic thermoplastic elastomer composition obtained from a mixture comprising: (1) 100 parts by weight of an olefinic elastomer which is made from ethylene and one or more α-olefins having 6 to 12 carbon atoms and has an α-olefin unit content of 26 to 30 wt.%, a density of 0.8 to 0.9 g/cm3, and a molecular weight distribution (M¿w?/Mn), in which Mw is the ratio of the weight-average molecular weight and Mn is the number-average molecular weight, as calculated through gel permeation chromatography (GPC) of less than 3.0, (2) 5 to 90 parts by weight of a propylene polymer, and (3) 5 to 250 parts by weight of an oil for rubbers, by cross-linking the mixture with either a free-radical initiator or a combination thereof with a cross-linking aid.</p> |
