Document Type and Number:
WIPO Patent Application WO/2023/176810
Kind Code:
A1
Abstract:
The purpose of the present disclosure is to provide: a thermoplastic elastomer composition which is capable of forming an appearance that has excellent scratch resistance and low gloss; and a method for producing this thermoplastic elastomer composition. The present disclosure provides a thermoplastic elastomer composition which contains a first composition that contains an olefin resin (A), an ethylene/α-olefin copolymer (B) and a crosslinking agent (F), and a second composition that contains a hydrogenated product (C) of a block copolymer which has at least one block that is mainly composed of a conjugated diene monomer unit and at least one block that is mainly composed of a vinyl aromatic monomer unit, wherein: the content of the component (B) is 10-180 parts by mass relative to 100 parts by mass of the component (A); the content of the component (C) is 170-500 parts by mass relative to 100 parts by mass of the component (A); and the ratio W1/W0 of the gel content W1 to the sum W0 of the content ratio of the component (B) and the content ratio of the component (C) is 0.01-0.70. The present disclosure also provides a method for producing this thermoplastic elastomer composition.
