PURPOSE: Provided are a polymer composite, its preparation method and a molded product for a seal, hose, belt, roller, bearing pad, stator, well head seal, valve plate, cable coating or pipe seal. CONSTITUTION: The polymer composite comprises at least one optically-hydrogenated carboxylated nitrile rubber polymer; at least one basic compound; at least one polyhalogenated hydrocarbon; optionally at least one filler; and optionally at least one crosslinking agent. Preferably the basic compound is hydroxides, oxides, carbonates or bicarbonates of an alkali metal, or hydroxides, oxides or carbonates of an alkaline earth metal; and the polyhalogenated hydrocarbon is a polyhalogenated alkane, a polyhalogenated alkene or a polyhalogenated aryl compound.
