  • Preparation of butadiene-based impact modifiers
    Patent number: 5599854
    Abstract: An improved process for preparing core/shell MBS modifiers is disclosed, wherein by adding feeds of the monomers which form the second and/or third stage polymers prior to completion of polymerization of the earlier stages, a process with substantially reduced polymerization time results with no loss in properties of the product. The process further includes agglomeration of the rubbery polymer to increase particle size during the polymerization process.
    Type: Grant
    Filed: November 16, 1995
    Date of Patent: February 4, 1997
    Assignee: Rohm and Haas Company
    Inventors: Edward J. Troy, Anibal Rosado
