A conjugated diene rubber gel comprising 80-99 weight % of conjugated diene monomer units and 20-1 weight % of aromatic vinyl monomer units and having a swelling index of 16 to 70 as measured in toluene. A rubber vulcanizate made from a rubber composition comprising this conjugated diene rubber gel and a rubber capable of being crosslinked with sulfur exhibits good abrasion resistance and low heat-build up without deterioration of mechanical properties, and thus, is suitable for tire materials. This conjugated diene rubber gel can be produced with high efficiency by emulsion-polymerization of a monomer mixture comprising 50-99.9 weight % of a conjugated diene monomer, 0-30 weight % of an aromatic vinyl monomer, 0-20 weight % of other ethylenically unsaturated monomer and 0.1-20 weight % of a crosslinking monomer.
A conjugated diene rubber gel comprising 80% to 99% by weight of conjugated diene monomer units and 20% to 1% by weight of aromatic vinyl monomer units and having a swelling index in the range of 16 to 70 as measured in toluene.
A conjugated diene rubber gel comprising 80 to 99% by weight of conjugated diene monomer units, 1% to 20% by weight of aromatic vinyl monomer units, 0% to 19% by weight of other ethylenically unsaturated monomer units and 0% to 1.5% by weight of crosslinking monomer units, and having a swelling index in the range of 16 to 70 as measured in toluene.
A conjugated diene rubber gel comprising 86 to 89.8% by weight of conjugated diene monomer units, 10% to 13.8% by weight of aromatic vinyl monomer units, 0% to 1% by weight of other ethylenically unsaturated monomer units and 0.2% to 0.5% by weight of crosslinking monomer units, and having a swelling index in the range of 20 to 40 as measured in toluene.
