Title:
RUBBER COMPOSITION AND PROCESS FOR PREPARING THE SAME
Document Type and Number:
WIPO Patent Application WO/1996/023027
Kind Code:
A1
Abstract:
A silica-containing diene rubber composition which is excellent in rebound resilience inductive of rolling resistance and has tensile strength and abration resistance equal or superior to those of carbon-black-containing diene rubber compositions and, further, good processability and hardness properties. The composition is characterized in that the diene rubber component is a hydroxylated diene rubber having a weight-average molecular weight of not less than 50,000 or a blend thereof with other diene rubber(s). Such a rubber composition is prepared by a process characterized in that either the hydroxylated diene rubber or the blend thereof is used as the diene rubber component and at least part of the necessary silica is mixed with the diene rubber component to prepare a mixture, which is then mixed with the rest of the silica and other compounding ingredients.
