A polymer composition contains: n(A) a conjugated diene-based polymer having a carbon-carbon unsaturated bond and exhibiting a value θ of 0.75 or more as determined by formula (i): θ = p + 0.5 × r / p + q + 0.5 × r + s wherein p, q, r, and s are respectively the proportions by mole of structural units represented by formulae (1), (2), (3), and (4) in the polymer:n nand n(B) at least one component selected from the group consisting of water-soluble particles and water-soluble fiber. |
