摘要：
A thermoplastic elastomer composition of the invention, formed by dynamically crosslinking a polymer composition including a rubber and an olefinic resin and having an average particle size of rubber particles within a specific range, shows an excellent balance of mechanical properties such as flexibility and elastic recovery, and a moldability. Also an inclusion of a (meth)acrylate resin and a hydrogenated diene polymer provides a composition particularly excellent in scratch resistance. Also an inclusion of a maleimide compound provides a composition particularly excellent in injection fusibility. Also an inclusion of an undenatured organopolysiloxane of a specific viscosity and a denatured organopolysiloxane provides a composition particularly excellent in initial slidability and durable slidability.
