Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a tire of a structural combination of tire tread and sidewall components with compositional limitations containing minimal, if any, of in situ formed alcohol and methyl isobutyl ketone byproducts. The tread component rubber composition contains pre-hydrophobated silica reinforcement. The sidewall component contains low unsaturation EPDM or brominated copolymer of isobutylene and p-methylstyrene and may contain pre-hydrophobated silica reinforcement. The silica reinforcement for said tread and sidewall components is a pre-hydrophobated precipitated silica. The pre-hydrophobated silica is prepared, prior to mixing with the elastomer(s), by reacting hydroxyl groups (e.g. silanol groups) contained on the surface of a precipitated silica with an alkoxyorganomercaptosilane or a combination of an alkoxyorganomercaptosilane and a substituted alkylsilane or with a bis-3(trialkoxysilylalkyl) polysulfide which contains an average of from 2 to 4 connecting sulfur atoms in its polysulfidic bridge to form a composite thereof. The alcohol byproduct therefrom is removed from the composite prior to its introduction into the rubber composition(s). In another aspect of the invention, the connecting sidewall rubber composition, and optionally the tread composition is free of N-(1,3-dimethylbutyl)-N′-phenyl-p-phenylenediamine antidegradant (referred herein to as 6PPD) in order to prevent in situ formation of methyl isobutyl ketone byproduct from the reaction of 6PPD with atmospheric oxygen and/or ozone.
