PROBLEM TO BE SOLVED: To provide a polymer alloy which has excellent oil resistance and ozone resistance, does not produce precipitates in gasoline, even when brought into contact with the gasoline for a long period, and is suitable as a material for fuel hoses, and to provide a molded article thereof. SOLUTION: This polymer alloy comprising 40 to 90 pts. wt. of a nitrile group-containing copolymer rubber (A) and 10 to 60 pts. wt. of an acryl rubber (B) containing≥50 wt. % of (meth)acrylate monomer units, wherein the total amount of the components (A) and (B) is 100 pts. wt., is characterized in that at least one of the components (A) and (B) is obtained by coagulating an emulsion containing an alkyl sulfate or an alkylbenzene sulfonate. A molded article obtained by cross-linking and molding the polymer alloy. The cross-linked product of the polymer alloy has excellent oil resistance and ozone resistance, scarcely produces precipitates in gasoline, even when brought into contact with the gasoline for a long period, and is suitable as a material for fuel hoses.
