A vulcanized thermoplastic olefinic rubber composition comprising at least one vulcanizable rubber (A) selected from the group consisting of ethylene-α-olefin copolymers, which contain an ethylene unit and a unit of an α-olefin having 3 to 20 carbon atoms, and which are produced with use of a metallocene catalyst, and an olefinic resin (B), wherein X and Y as defined below of said (A) are from 1 to 40% and from 0.02 to 0.5, respectively,n n X =( W 2/ W 0)×100(%)n n Y=W 2/ W 1n nwherein W 1 is a weight of a swollen vulcanized rubber (A), which is obtained when (A) in an amount of W 0 is extracted with hot xylene, and W 2 is a weight measured after drying of the above-mentioned swollen vulcanized rubber (A). |
