THERMOPLASTIC ELASTOMER COMPOSITION AND METHOD FOR PRODUCING THERMOPLASTIC ELASTOMER COMPOSITION

Abstract: an object of the present disclosure is to provide a thermoplastic elastomer composition having excellent scratch resistance and being capable of forming a low gloss appearance and a method for producing a thermoplastic elastomer composition. the present disclosure provides a thermoplastic elastomer composition including a first composition containing an olefin-based resin (a), an ethylene/�-olefin copolymer (b), and a crosslinking agent (f), and a second composition containing a hydrogenated product (c) of a block copolymer having at least one block mainly including a conjugated diene monomer unit and at least one block mainly including a vinyl aromatic monomer unit, wherein the content of the component (b) is 10 to 180 parts by mass based on 100 parts by mass of the component (a); the content of the component (c) is 170 to 500 parts by mass based on 100 parts by mass of the component (a); and a ratio w/wis 0.01 to 0.70, where wo denotes the sum of a content rate of the component (b) and a content rate of the component (c), and wdenotes a gel content, and also provides a method for producing the thermoplastic elastomer composition.
