摘要： It has been unexpectedly determined that isoprene-butadiene rubber having a high glass transition temperature within the range of about −40° C. to about −25° C. (high Tg IBR) can be loaded with silica as a filler and utilized in manufacturing tire treads that have outstanding performance characteristics. For instance, such tire treads offer lower hysteresis at high temperatures (improved rolling resistance) and higher hysteresis at low temperatures (improved wet traction characteristics). By utilizing high Tg IBR in tire tread compounds, the maximum benefits of silica compounding can be realized without the need for solution or emulsion styrene-butadiene rubber (SBR) in the tread rubber formulations. The tire tread rubber formulations of this invention will normally contain about 20 phr (parts per 100 parts of rubber) to about 100 phr of the high Tg IBR. In other words, the tread rubber will normally contain at least 20 phr of the high Tg IBR and can contain up to 100 phr of the high Tg IBR. The tread compound will also contain 40 phr to 150 phr of a filler with the proviso that at least about 20 phr of silica is included in the filler. The tire tread compound will also contain a silica coupling agent. This invention more specifically discloses a tire tread rubber composition which is comprised of (1) at least about 20 phr of an isoprene-butadiene rubber having a glass transition temperature which is within the range of about −40° C. to −25° C., (2) 40 phr to 150 phr of a filler, with the proviso that the filler contains at least about 20 phr of silica, and (3) a silica coupling agent.

This catalyst system is comprised of (a) organo aluminum compounds, (b) organo lithium compounds, (c) a barium compound selected from barium salts of (i) di(ethylene glycol) ethyl ether, (ii) di(ethylene glycol) propyl ether, (iii) di(ethylene glycol) hexyl ether, (iv) di(N,N-dimethyl amino glycol) ethyl ether, (v) menthol and thymol in the presence of polar modifier consisting of water, alcohols, amines, thiols, phosphates and phosphites. The trans polymers and copolymers of this invention made with the above catalyst system typically have a glass transition temperature ranging from −97° C. to −40° C., a melt temperature ranging from −30° C. to +30° C., and a number average molecular weight from 20,000 to 250,000. The inclusion of such polar modifiers in the barium catalyst system results in a high styrene content in copolymerization, a high trans content, and high molecular weight. Copolymers of conjugated diolefin monomers and vinyl aromatic monomers made with the catalyst system of this invention also have a tapered macrostructure.
