<p>A conjugated diene rubber gel comprising 80 to 99 wt% of conjugated diene monomer units and 20 to 1 wt% of aromatic vinyl monomer units and exhibiting a swelling value of 16 to 70 as determined in toluene. Products obtained by crosslinking a rubber composition comprising this rubber gel and a sulfur-crosslinkable rubber exhibit excellent resistances to wear, abrasion, and heat build-up with the excellent mechanical characteristics inherent therein being kept, thus being suitable for tire materials. The conjugated diene rubber gel can be efficiently produced by emulsion-copolymerizing 50 to 99.9 wt% of a conjugated diene monomer with 0 to 30 wt% of an aromatic vinyl monomer, 0 to 20 wt% of other ethylenically unsaturated monomer, and 0.1 to 20 wt % of a crosslinking monomer.</p> |
