Title:

THERMOPLASTIC ELASTOMER COMPOSITION, METHOD FOR PRODUCING SAME AND MOLDED BODY

Document Type and Number:

WIPO Patent Application WO/2017/213216

Kind Code:

A1

Abstract:

The present invention relates to a thermoplastic elastomer composition, a method for producing the thermoplastic elastomer composition, and a molded body. A thermoplastic elastomer composition according to the present invention contains a crystalline olefin resin (A) having a melting point of 100°C or more, an olefin resin (B) satisfying conditions (B-1) to (B-3), and an ethylene/α-olefin copolymer (C) at a weight ratio (A)/((B) + (C)) of from 70/30 to 30/70 and at a weight ratio (B)/(C) of from 100/0 to 1/99. (B-1) The olefin resin has a main chain configured from an ethylene copolymer and a side chain configured from an ethylene polymer or a propylene polymer; the ethylene copolymer comprises a repeating unit derived from ethylene and a repeating unit derived from one or more α-olefins selected from among α-olefins having 3-20 carbon atoms; and the repeating units derived from α-olefins are contained in an amount of 10-50 mol% relative to all the repeating units contained in the main chain. (B-2) The melting point as determined by DSC is 60°C to 170°C. (B-3) The Tg as determined by DSC is -80°C to -30°C.
