Document Type and Number:
Japanese Patent JP3488926
Kind Code:
B2
Abstract:
There is provided a silica-containing diene rubber composition superior in resiliene (which is an indication of rolling resistance), at least equal, in tensile strength and abrasion resistance, to carbon black-containing diene rubber compositions, and good in processability and hardness property. The silica-containing diene rubber composition is characterized by containing, as the diene rubber component, a hydroxyl group-containing diene rubber having a weight-average molecular weight of 50,000 or more, or a blend of the hydroxyl group-containing diene rubber and other diene rubber. This composition is produced by a process which uses, as the diene rubber component, a hydroxyl group-containing diene rubber having a weight-average molecular weight of 50,000 or more, or a combination of the hydroxyl group-containing diene rubber and other diene rubber and wherein the mixing of components is conducted by mixing the diene rubber component with at least part of a required amount of silica and then mixing the resulting mixture with the remainder of silica and other compounding agents.
