  • Processes for making masterbatches of rubber and silica
    Patent number: 11098169
    Abstract: A process is provided for making a silica masterbatch, that contains silica and solution-made rubber. The silica masterbatch has physical properties similar to those found in a comparable dry-mixed composition, but the silica masterbatch can be incorporated more easily and less expensively into tires and other rubber products than the dry-mixed composition. A process is also provided for making a masterbatch of silica, a solution-made rubber and an emulsion-made rubber.
    Type: Grant

  • Pressure Sensitive Adhesive Soluble in Acetone
    Publication number: 20120077916
    Abstract: An emulsion polymerization copolymer comprising 59-77 phr butadiene, 10-16 phr styrene; 10-16 phr acrylonitrile; and from 3-9 phr methacrylic acid is soluble in acetone for U.S. EPA-exempt, low-VOC emissions, while also soluble in toluene. The composition is formulated with a tackifying resin; a plasticizer oil; and a U.S. EPA-exempt solvent, preferably acetone, to make an adhesive. The formulation is particularly useful as a pressure sensitive adhesive for tape and for making shoes.
