Title:
THERMOPLASTIC ELASTOMER COMPOSITION, MOLDED BODY OF SAME AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2018/181121
Kind Code:
A1
Abstract:
The present invention relates to: a thermoplastic elastomer composition which contains 30-60 parts by mass of a crystalline olefin polymer (A), 100 parts by mass of an ethylene/α-olefin (having 3-20 carbon atoms)/non-conjugated polyene copolymer (B) satisfying the requirements (1) and (2) described below, 20-120 parts by mass of at least one polymer (C) which is selected from the group consisting of copolymers of an aromatic vinyl compound and a conjugated diene compound, hydrogenated products of the copolymers of an aromatic vinyl compound and a conjugated diene compound, and hydrogenated conjugated diene compound polymers, and 4-15 parts by mass of a phenolic resin-based crosslinking agent (D); a molded body of this thermoplastic elastomer composition; and a method for producing this thermoplastic elastomer composition.
(1) The Mooney viscosity [ML(1+4) 125°C] is 50-230.
(2) The content of a structural unit derived from ethylene is 50-95% by mole.
