WIPO Patent Application WO/2022/230785
Kind Code:
A1
Abstract:
This resin composition contains, as component (x), a hydrogenated product (X) of a block copolymer having a polymeric block (A-1) derived from an aromatic vinyl compound and having a polymeric block (B-1) derived from a conjugated diene compound, and, as component (y), a block copolymer (Y0) having a polymeric block (A-2) derived from an aromatic vinyl compound and having a polymeric block (B-2) derived from a conjugated diene compound, or a hydrogenated product (Y) of the block copolymer (Y0), and satisfies conditions [1]-[4]. [1] The glass transition temperature of component (x) is at least -40°C. [2] The glass transition temperature of component (y) is at most -50°C. [3] A ratio Mx/My of the mass Mx of component (x) with respect to the mass My of component (y) in the resin composition is 1/99 to 99/1. [4] The polymeric block (B-2) includes a structural unit derived from β-farnesene.
