Claims5
A modified block copolymer composition, comprising:
- a modified block copolymer containing at least one aromatic vinyl polymer block and at least one conjugated diene polymer block, and having at least one modified terminal modified with a compound having a silicon atom and further comprising an acrylic group and/or a methacrylic group,
- wherein the modified terminal has a structure in which a hydrocarbyloxysilane compound (β) having an acrylic group and/or a methacrylic group is bonded via a hydrocarbyloxysilane compound (α) without either of an acrylic group or a methacrylic group.
