Abstract

PURPOSE:A rubber composition with excellent workability and thermal aging resistance, which is prepared by compounding an ethylene-alpha-olefin-polyene copolymer rubber and an ethylene-alpha-olefin copolymer rubber with a specified polybutene in addition to a specified vulcanizer, etc. CONSTITUTION:A thermal aging-resisting rubber composition, comprising (A) an ethylene-alpha-olefin-polyene copolymer rubber of molratio of the ethylene unit to the alpha-olefine unit about 55/45-95/5, (B) an ethylene-alpha-olefin copolymer rubber of mole ratio of the ethylene unit to the alpha-olefin unit about 55/45-95/5, contg. no polyene component, in a weight ratio of A/B of about 55/45-99/10, (C) at least about 0.003mol part org. peroxide vulcanizer, (D) at least about 0.003mol part vulcanizing auxiliary, (E) at least about 0.5pt.wt. antioxidant and (F) at least about 5-50pts.wt. low-molecular polybutene substantially contg. no C-C unsaturated bond, each based on 100pts.wt. tolal of said A and B components.
