摘要： A rubber composition which comprises a rubber component comprising at least one rubber selected from natural rubber and synthetic diene rubbers and, per 100 parts by weight of the rubber component, 30 to 200 parts by weight of a modified carbon black having at a surface thereof an Si—O—C structure or an Si—C structure in which the carbon atom bonded directly to the Si atom is an aromatic carbon atom, and a pneumatic tire prepared by using the rubber composition. The modified carbon black can be obtained by bringing carbon black into contact with a silicon compound, such as a compound represented by a general formula: (R1O)mSiR24−m in a gas phase (in the formula, R1 represents an alkyl group having 1 to 3 carbon atoms, R2 represents an alkyl group having 1 to 3 carbon atoms or phenyl group and m represents an integer of 2 to 4). The rubber composition exhibits hysteresis loss increased selectively at a high temperature region. The modified carbon black can be advantageously used in the rubber composition. The pneumatic tire in which the rubber composition is used for a tread rubber is advantageously used as a high performance tire exhibiting a remarkably improved gripping property.

摘要： A dispersion improved carbon black compounded rubber composition comprises a rubber component and a reinforcing carbon black in an amount of from 30 to 150 parts by weight with respect to 100 parts by weight of the rubber component. The rubber component is selected from a group consisting of a natural rubber, synthetic isoprene rubber and a mixture thereof, or a blend of this rubber component with a diene base synthetic rubber other than this rubber component. The reinforcing carbon black has a specific surface area of from 70 to 200 m.sup.2 /g when measured by a nitrogen adsorption method and a DBP value of from 80 to 130 ml/100 g, and is obtained by introducing mainly phenolic hydroxide groups into the surface of the carbon black through plasma treatment at low temperatures or by introducing carboxyl groups and the phenolic hydroxide groups thereinto through plasma treating at low temperatures and neutralizing the thus introduced acid groups.
