Rubber compositions for hose production having excellent scorch resistance, extrudability, moisture impermeability, weatherability (ozone resistance), and compression set resistance, as well as a hose produced therefrom, and in particular, a refrigerant hose and its production process are provided. More illustratively, a composition comprising (A) a brominated copolymer of an isomonoolefin and a p-alkylstyrene (PMS) wherein PMS content, bromine (Br) content, and Br/PMS weight ratio are within particular ranges; (B) zinc white; and (C) a brominated alkylphenol resin, and a hose wherein such composition is used for the inner tube and/or the outer cover are provided. Also provided are a composition comprising (A) the brominated copolymer rubber and (D) an inorganic laminar compound; a hose produced by using such composition for the inner tube; and a process for producing a refrigerant hose from such a composition by in-die drawing process.
