    • A pellet comprising 100 parts by weight of an ethylene/α-olefin/non-conjugated polyene copolymer (A) containing a constitutional unit derived from non-conjugated polyene represented by a specific Formula, 1 to 150 parts by weight of a plasticizer (B) relative to 100 parts by weight of the above (A), and 0 to 30 parts by weight of a thermoplastic resin (C) relative to 100 parts by weight of the above (A), is obtained, and a vulcanized rubber or a thermoplastic elastomer which does not cause blocking and has excellent crosslinking reactivity and thus excellent properties can be prepared therefrom. According to a process for preparation of a thermoplastic elastomer using the above-mentioned pellet, a thermoplastic elastomer having excellent compression set or dispersibility can be economically and efficiently prepared. In particular, since it can be prepared continuously using a twin screw extruder, the process is excellent from an industrial viewpoint. According to a process for preparation of a pellet of an ethylene copolymer rubber composition according to the invention, it is possible to obtain a copolymer pellet which has a low degree of crystallinity, does not cause blocking, has excellent crosslinking reactivity and has carbon-carbon double bonds of excellent crosslinking reactivity.
