Summary:PROBLEM TO BE SOLVED: To economically produce a vulcanized sponge rubber article from an ethylene/α-olefin/nonconjugated copolymer rubber in a compositional region where the low-temperature characteristics are excellent. SOLUTION: The method for producing a vulcanized rubber sponge rubber article from an ethylene/α-olefin/nonconjugated copolymer rubber comprises the step of kneading the following compounding materials: (A) nonsticking pellets obtained by cutting a coated product prepared by coating with a thermoplastic resin an ethylene/α-olefin/nonconjugated diene copolymer rubber having an ethylene content of 40 to 60 wt.% and a nonconjugated diene content of 5 to 20 wt.% and having an ML viscosity (ML1+4, 125°C) of 40 to 250 as measured at 125°C, (B) a reinforcement, and (C) a softener.
