Abstract
A base rubber selected from natural rubber and diene rubber is blended with, based on 100 parts by weight of the base rubber, 0.5 to 5 parts by weight of a 2,2,4-trimethyl-1,2-dihydroquinoline polymer having a primary amine content of not more than 1% by weight, a monomer content of not more than 3% by weight and a dimer content of at least 30% by weight. The resulting rubber composition is vulcanized in contact with a reinforcing material such as an organic fiber or a steel cord. The rubber article thus obtained and reinforced with the reinforcing material is excellent in adhesiveness between the rubber and the reinforcing material, and further in thermal resistance.
