ABSTRACT:
A primary modified polymer composed of (1) a hydrogenated polymer obtained by hydrogenating at least one non-hydrogenated polymer selected from the group consisting of polymers comprising conjugated diene monomer units and copolymers comprising conjugated diene monomer units and vinyl aromatic monomer units and (2) groups of a primary modifier having a functional group which are bonded to the polymer (1), which has a specific vinyl aromatic monomer unit content, a specific vinyl aromatic polymer block content, a specific weight-average molecular weight, and a specific degree of hydrogenation of the double bonds of conjugated diene monomer units; a secondary modified polymer obtained by reacting a primary modified polymer composed of (β) a base polymer and (γ) groups of a primary modifier having a functional group which are bonded to the polymer (β) with a secondary modifier; and compositions comprising the primary or secondary modified polymer and at least one other component.
