摘要：
A cured ethylene·α-olefin copolymer-based rubber composition excellent in weathering resistance property is produced by curing with an organic peroxide an uncured rubber composition comprising 100 parts by weight of an ethylene ·α-olefin copolymer-based rubber, 1 to 10 parts by weight of a hindered amine-based weathering agent, 0.01 to 10 parts by weight of a phenol-based antioxidant, 0.01 to 10 parts by weight of a sulfur-based antioxidant, 0.01 to 10 parts by weight of a phosphite ester-based antioxidant, and 1 to 10 parts by weight of a benzotriazole-based ultraviolet absorber.
