  • Patent number: 6670416
    Abstract: In tire tread formulations, blends of rubbers having low and high glass transition temperatures have significant advantages over blends made with rubbers having intermediate glass transition temperatures. However, blends of rubbers having low and high glass transition temperatures exhibit poor processability. This invention deals with improving the processability of tire tread formulations which are made by blending rubbers having both low and high glass transition temperatures that offer ultra low rolling resistance without sacrificing rolling resistance or tread wear characteristics. This invention more specifically discloses a tire tread rubber composition which is comprised of (a) about 60 phr to about 90 phr of a high cis-1,4-polybutadiene rubber, wherein the high cis-1,4-polybutadiene rubber has a glass transition temperature which is within the range of about −104° C. to about −80° C.

  • Patent number: 6649681
    Abstract: The present invention provides an adhesive composition for use in bonding a polymeric fitting to an olefin-containing component of an article used in medical applications. The adhesive composition according to the invention includes an adhesive polymer system dissolved in a solvent system. The solvent system includes an organic solvent having a solubility parameter within the range of from about 7.5 to about 10 (cal/cm3)1/2. Subsequent to forming a bond between the polymeric fitting and the olefin-containing component, the adhesive composition can meet the requirements for USP Class VI materials. In a preferred embodiment of the invention, the adhesive composition includes a low shear mixture of an adhesive polymer system including an atactic polypropylene and a low density polyethylene that is dissolved in a solvent system including a blend of d-limonene and a ketone selected from the group consisting of 4-heptanone and cyclohexanone.
