| titleOfInvention | Tire tread compound |
| abstract | Tire tread compounds made from styrene-butadiene rubber filled with high levels of silica are obtainable by making the styrene-butadiene rubber by a process which comprises (1) introducing water, a soap system, a radical generator, 1,3-butadiene monomer and styrene monomer in a first polymerization zone; (2) copolymerizing the 1,3-butadiene monomer and the styrene monomer in the first polymerization zone to a monomer conversion in the range of about 15% to 40% to produce a low conversion polymerization medium; (3) introducing the low conversion polymerization medium into a second polymerization zone; (4) introducing an additional amount of 1,3-butadiene monomer and an additional amount of styrene monomer into the second polymerization zone; (5) continue copolymerization until a monomer conversion of at least about 50% is reached to produce the styrene-butadiene rubber latex; and (6) recovering the styrene-butadiene rubber from the latex. Tire tread compounds of this type with high contents of silica filling show both a lower rolling resistance and excellent traction properties. |
