    摘要： The present invention pertains to a process for preparing a rubber precursor or a rubber composition comprising a modified inorganic oxygen-containing particulate material comprising the steps of: a) preparing a mixture of the modified inorganic oxygen-containing particulate material and a first solvent; and b1) adding the mixture to a rubber precursor comprising at least one polymer and optionally a second solvent; or b2) adding the mixture to a rubber composition comprising at least one monomer of a rubber precursor and optionally a second solvent, and polymerising the monomer(s) to form the rubber precursor; c) optionally cross-linking the rubber precursor in the presence of a cross-linking agent to form a rubber composition; and d) optionally removing the first and/or second solvents before, during or after any of the steps b1), b2), and c). The invention further pertains to rubber compositions comprising rubber and inorganic oxygen-containing particulate material modified with a coupling agent.

    摘要： The invention relates to a silica-filled, sulfur-vulcanizable rubber composition comprising an unsaturated rubber, 20 to 100 phr of a silica, 1.6 to 8 phr of a silica coupling agent, 0.05 to 5 phr of an antidegradant, 0.1 to 5 phr of a vulcanization accelerator, 0.1 to 10 phr of sulfur, and 0.5 to 5 phr of a quinone diimine, with the proviso that the antidegradant is not a quinone diimine. The invention also relates to a vulcanization process comprising mixing and heating said rubber composition and to rubber articles, such as pneumatic tires, comprising the rubber vulcanizate obtained by said process.
