摘要： High viscosity elastomers are often difficult to utilize in rubber compositions without first creating a pre-blend of the high viscosity elastomer and a rubber processing oil to reduce their overall viscosity. This invention relates to utilization of a specialized pre-blend of high viscosity and low viscosity elastomers for use in rubber compositions and to the resulting rubber composition. The use of such resulting rubber composition may be for component(s) of tires, particularly including tire treads. The specialized pre-blend of high and low viscosity elastomers is required to be created by blending individual latices or, alternatively, by blending individual polymerizates of elastomers with diverse viscosities.

摘要： This invention relates to a tire tread compound that is easily processable which can be used to improve the treadwear, rolling resistance and traction characteristics of tires. The tire tread compounds of this invention are a blend of tin-coupled polybutadiene, high vinyl polybutadiene and natural rubber. This blend of low glass transition temperature rubber and high glass transition temperature rubber is surprisingly easy to process which makes the concept of this invention commercially feasible. Thus, the tire tread compounds of this invention can be utilized in making tires having greatly improved traction characteristics and treadwear without sacrificing rolling resistance. These improved properties may be due, in part, to better interaction and compatibility with carbon black and/or silica fillers. The polybutadiene in the blend can be asymmetrical tin-coupled to further improve the cold flow characteristics of the rubber blend. Asymmetrical tin coupling in general also leads to better processability and other beneficial properties. This invention more specifically discloses a tire tread rubber composition which is comprised of (1) from about 20 phr to about 60 phr of tin-coupled polybutadiene rubber, (2) from about 20 phr to about 60 phr of a rubber selected from the group consisting of natural rubber and synthetic polyisoprene and (3) from about 5 phr to about 40 phr of high vinyl polybutadiene rubber.
