    • There is provided a thermoplastic elastomer composition including an ethylene/α-olefin copolymeric rubber (A1) or an extended rubber (X) comprising an ethylene/α-olefin copolymeric rubber (A2) and a mineral oil softener (E2), and a thermoplastic α-olefin resin (B) comprising a α-olefinic crystalline thermoplastic resin (B1) and/or a α-olefinic amorphous thermoplastic resin (B2), an unmodified organopolysiloxane (C), a viny-terminated organopolysiloxane (D), and a mineral oil softener (E1); and molded article produced by forming the thermoplastic elastomer composition. There is provided a thermoplastic elastomer composition and a molded article thereof having excellent molding appearance by imparting an initial sliding ability with an organopolysiloxane having low viscosity and by adding a crosslinked vinylated organopolysiloxane to a thermoplastic elastomer composition to exhibit durable abrasion resistance (long term sliding ability).
    • 提供了包含乙烯/α-烯烃共聚橡胶(A1)或包含乙烯/α-烯烃共聚橡胶(A2)和矿物油软化剂(E2)的延伸橡胶(X))和热塑性弹性体组合物的热塑性弹性体组合物 包含α-烯烃结晶热塑性树脂(B1)和/或α-烯烃无定形热塑性树脂(B2)的α-烯烃树脂(B),未改性的有机聚硅氧烷(C),乙烯基末端的有机聚硅氧烷(D)和 矿物油软化剂(E1); 和通过形成热塑性弹性体组合物制备的模制品。 提供一种热塑性弹性体组合物及其模塑制品,其通过赋予具有低粘度的有机聚硅氧烷具有初始滑动能力和通过向热塑性弹性体组合物加入交联的乙烯基化有机聚硅氧烷以显示出耐久的耐磨性(长期滑动性 )。
