THERMOPLASTIC ELASTOMER COMPOSITION AND PROCESS FOR PRODUCING THE SAME

摘要

A thermoplastic elastomer composition which is obtained by dynamically crosslinking a polymer composition comprising a rubber, an olefin resin, etc. and in which the rubber particles have an average particle diameter in a specific range. Due to this constitution, the composition has an excellent balance between mechanical properties, such as flexibility and elastic recovery, and moldability. When the composition contains a methacrylate resin and a hydrogenated diene polymer, it especially has excellent scratch resistance. When the composition contains a maleimide compound, it especially has excellent injection fusibility. When the composition contains an unmodified organopolysiloxane having a specific viscosity and a modified organopolysiloxane, it is excellent especially in initial sliding properties and long-term sliding properties.
