Document Type and Number:

WIPO Patent Application WO/2020/158678

Kind Code:

A1

Abstract:

According to the present invention, a rubber composition is configured to contain, as a polymer (A), a polymer which has a carbon-carbon unsaturated bond, and which comprises 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) so that the value α represented by mathematical formula (i) is from 0.70 to 0.99 (inclusive) if p, q, r and s are the respective constituent ratios (molar ratios) of the structural units in the polymer, and to contain, as a resin (B), a thermoplastic resin; and this rubber composition contains the polymer (A) in an amount of 60-95% by mass relative to the total amount of the polymer (A) and the resin (B). (i): α = (p + (0.5 × r))/(p + q + (0.5 × r) + s)
