An ethylene-alkyl acrylate copolymer rubber composition, which comprises 100 parts by weight of ethylene-alkyl acrylate copolymer rubber having an amine vulcanizable group, 0-60 parts by weight of EPDM, 5-40 parts by weight of a plsticizer, 0.5-4 parts by weight of an organic peroxide cross-linking agent, 0.5-4 parts by weight of an amine-based cross-linking agent, and preferably 0.1-0.5 parts by weight of a sulfur compound. Oil extended EPDM can be used in place of EPDM or EPDM and the plasticizer. Use of 1-30 parts by weight of α-olefin oligomer together with 5-50 parts by weight of EPDM can improve the processability (non-adhesion of product itself to a mold or prevention of bleed occurrence).
