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