Abstract

A thermoplastic elastomer composition prepared by dynamically treating with heat (a) an oil-extended ethylene-based copolymer rubber which comprises an ethylene-based copolymer rubber with an intrisic viscosity [.eta.] in the range from 4.3 to 6.8 dl/g when measured at 135.degree. C. in decalin and a mineral oil softening agent and (b) an olefin-based resin, in the presence of a crosslinking agent. The composition exhibits well-balanced and excellent elasticity recoverability and moldability, and can produce molded articles with superior appearance.
