Rubber composition

Abstract

The problem of the present disclosure is to provide a rubber composition with improved tensile strength at break (TB) and elongation at break (EB), and the solution is a rubber composition including a rubber component (A) and a crosslinking agent (B), wherein the rubber component (A) contains a polymer (A1) having at least two hydroxyl groups and a diene unit, at least two hydroxyl groups in the polymer (A1) are bonded to adjacent carbon atoms, and a content of the crosslinking agent (B) is 0.1 to 8 parts by mass per 100 parts by mass of the rubber component (A) and 0.1 to 80 parts by mass per 100 parts by mass of the polymer (A1).

Dependencies are inferred from the claim text.
