Abstract: An elastomeric blend is described, which can be used for preparing electric cables comprising one or more polymers selected from: (i) a polymer (Base 1) obtained by means of shear treatment, in the presence of hydroperoxides, of a polymeric base essentially consisting of elastomeric copolymers of ethylene with propylene (EPM) or EPDM terpolymers and relative blends, EPDM terpolymers being preferred; (ii) a copolymer of ethylene with alpha olefins, vinyl acetate or a derivative of acrylic acid (Base 2); said copolymer (ii) having a melting point lower than 115null C., preferably lower than 100null C.
