摘要： The process of this invention can be utilized to improve the adhesion between rubber components. It is generally most useful for improving the adhesion between two different pre-cured rubber components or for improving the adhesion between a pre-cured rubber component and an uncured (green) rubber component. However, the technique of this invention can also be employed to improve the adhesion between two uncured rubber components. The technique of this invention is based upon the unexpected discovery that low molecular weight trans-1,4-polybutadiene containing rubber compounds can be used to improve the adhesion between rubber components. This invention more specifically reveals a technique for improving the adhesion between a first rubber component and a second rubber component in a process for manufacturing a cured rubber article, said technique comprising the steps of: (1) positioning a layer of an adhesion-promoting rubber composition which is comprised of a low molecular weight trans-1,4-polybutadiene rubber between the first rubber component and the second rubber component, (2) bringing the first rubber component into contact with one side of the layer of adhesion-promoting rubber composition and bringing the second rubber composition into contact with the other side of the layer of adhesion-promoting rubber composition and (3) curing the first rubber composition, the second rubber composition and the adhesion-promoting rubber composition together under conditions of heat and pressure to produce the cured rubber article.

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.
