Abstract:
A hydrogenated conjugated diene-based polymer which has a structure formed by bonding a nitrogen-containing compound having two or more alkoxysilyl groups and two or more nitrogen atoms with a plurality of conjugated diene-based polymer chains, wherein: when a composition ratio (molar ratio) in the hydrogenated conjugated diene-based polymer of each of a structural unit represented by formula (1), a structural unit represented by formula (2), a structural unit represented by formula (3), and a structural unit represented by formula (4) is p, q, r, and s, respectively, a value a represented by formula (i) is 0.80 or more and 0.97 or less, and an equilibrium storage modulus E′ of the hydrogenated conjugated diene-based polymer is 2.4 MPa or more, α=(p+(0.5×r))/(p+q+(0.5×r)+s) (i)
