A polymer composition containing: (A) a polymer in which the value [alpha] represented by formula (i) is 0.60 or more, where p, q, r and s are the composition ratios (molar ratios) 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) in the polymer, respectively, and p, q, r and s are the composition ratios (molar ratios) of the structural unit represented by formula (1), the structural unit represented by formula (2), the structural unit represented by formula (3) and the structural unit represented by formula (4); the weight average molecular weight (Mw) in terms of polystyrene as measured by gel permeation chromatography is 1.0 * 105 to 2.0 * 106, and contains a carbon-carbon unsaturated bond; and (B) a paraffin wax having a melting point of 70 DEG C or higher. Alpha = (p + (0.5 * r))/(p + q + (0.5 * r) + s)... (i)
