Document Type and Number:
WIPO Patent Application WO/2023/127895
Kind Code:
A1
Abstract:
Provided are a thermoplastic elastomer composition in which the occurrence of bleeding is suppressed, and which is capable of improving grip properties and is suitable for masterbatches, a pellet of the thermoplastic elastomer composition, and a method for producing the thermoplastic elastomer composition. Additionally provided are a resin composition containing the thermoplastic elastomer composition, and a method for producing the resin composition. The thermoplastic elastomer composition comprises: a block copolymer (X) that includes a polymer block (A) containing a structural unit derived from an aromatic vinyl compound, and a polymer block (B) containing a structural unit derived from a conjugated diene compound; and a liquid rubber component (Y). The polymer block (B) includes a polymer block (B-1) containing a structural unit derived from β-farnesene.
