  • Thermoplastic elastomer composition, use thereof, method for producing same, ethylene/?-olefin/unconjugated polyene copolymer and use thereof
    Patent number: 11078352
    Abstract: [Problem] The purpose of the invention is to provide: a thermoplastic elastomer composition capable of providing molded articles that are lightweight, have better oil resistance than those provided by conventional cross-linked thermoplastic elastomers, and have hardness and mechanical properties such as tensile strength and tensile elongation that are equal to or superior to those provided by conventional cross-linked thermoplastic elastomers; and an ethylene/?-olefin/unconjugated polyene copolymer having little compression set at low temperature as well as flexibility and an excellent balance of rubber elasticity at low temperature and tensile strength at normal temperature.
    Type: Grant
    Filed: March 17, 2016
    Date of Patent: August 3, 2021
    Assignee: MITSUI CHEMICALS, INC.
    Inventors: Kotaro Ichino, Tomohiro Yamaguchi, Yukio Aita, Yuji Noguchi
