Document Type and Number:
Japanese Patent JP2682148
Kind Code:
B2
Abstract:
A rubber composition comprising 100 parts by weight of a rubber component which comprises at least 30% by weight of an emulsion polymerization rubber which is a conjugated diene polymer rubber or conjugated diene-styrene copolymer rubber obtained by emulsion polymerization, has a bound styrene content of 0-65% by weight, contains 20-35% by weight of a component having a molecular weight of not more than 150,000 as measured by a gel permeation chromatography and has a Mooney viscosity, ML1+4(100 DEG C), of 60-160 and a Mooney viscosity difference ( DELTA MV) of -20 to +5 as defined by the following equation: DELTA MV = ML1+4(100 DEG C) - ML1+15(100 DEG C) and 45-200 parts by weight of carbon black. Said rubber composition is excellent in abrasion resistance, breaking strength and high histeresis property in uses in which carbon black or oil is blended at a high-filling rate.
