(57) [Abstract] [PROBLEMS] To provide a novel ethylene copolymer composition which is excellent in mechanical properties such as strength and hardness and cold resistance, and which has an excellent property balance in consideration of kneading and processability. provide. SOLUTION: The composition comprises the following components (A), (B), It is characterized by containing (C) and (D). (A) Ethylene, an α-olefin having 6 to 12 carbon atoms, and a non-conjugated diene, having an ethylene content of 70 to 95 mol%, an iodine value of 0.5 to 50, and a polystyrene reduced weight average molecular weight of 50,000 to 500,000 by GPC measurement. Ethylene / α -Olefin / non-conjugated diene copolymer, (B) filler, (C) Plasticizer, (D) Vulcanizing agent and / or crosslinking agent. |
