PROBLEM TO BE SOLVED: To provide an oil- and weather-resistant rubber composition having excellent gasoline permeability resistance and excellent strengths, oil resistance and weather resistance (ozone resistance). SOLUTION: The rubber composition comprises a fluorine resin äcomponent (A)} and an unsaturated nitrile-conjugate diene polymer äcomponent B} comprising a structural unit (b1) originated from a conjugate diene monomer, a structural unit (b2) originated from an unsaturated nitrile monomer, a structural unit (b3) originated from a fluorine-containing (meth)acrylate and a structural unit (b4) originated from another monomer copolymerizable with (b1)-(b3). Molded products prepared by molding processing the rubber composition is provided. The rubber composition is useful for gasoline feed hoses and the like. COPYRIGHT: (C)2009,JPO&INPIT
