Document Type and Number:
WIPO Patent Application WO/2021/039985
Kind Code:
A1
Abstract:
A polymer composition containing: (A) a polymer having a carbon-carbon unsaturated bond wherein, defining p, q, r, and s as the component 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), respectively, in the polymer, the value of α represented by numerical expression (i) is 0.60 or higher, and the polystyrene-equivalent weight average molecular weight (Mw) measured by gel permeation chromatography is 1.0 × 105 to 2.0 × 106; and (B) paraffin wax with a melting point of 70 °C or higher. α = (p + (0.5 × r)) / (p + q + (0.5 × r) + s)... (i)
