Document Type and Number:
Japanese Patent JP4027094
Kind Code:
B2
Abstract:
A diene-based rubber composition which has excellent processability and an improved balance between low rolling resistance and wet skid resistance and is improved in strength properties, etc. The composition comprises: 100 parts by weight of (A) a raw rubber comprising a diene-based rubbery polymer which is (A-1) a rubbery conjugated-diene polymer or rubbery conjugated-diene/styrene copolymer and in which (1) more than 60 wt.% thereof has been modified by reacting active ends of the rubbery polymer with a polyfunctional compound having two or more epoxy groups per molecule, (2) the molecular weight distribution Mw/Mn of the polymer is 1.05 to 3.0, and (3) the weight-average molecular weight of the polymer is 100,000 to 2,000,000; 1 to 100 parts by weight of (B) an extender oil for rubbers; 25 to 100 parts by weight of (C) reinforcing silica; and 1.0 to 20 parts by weight of (D) a combination of a vulcanizing agent and a vulcanization accelerator.
