  • Emulsion polymer of heterogeneous molecular weight and preparation thereof
    Patent number: 4501845
    Abstract: Disclosed is a polymer and its preparation by reacting part of the monomers in the reactor in such a way as to obtain a high molecular weight product, and reacting at least one other portion of the monomer in the same reactor in such a way as to obtain at least one low molecular weight fraction. The products are useful in contact adhesives, particularly when blended with an aminoplast or phenoplast as a tackifier and crosslinker, and with a thickening agent such as polyvinyl alcohol.
    Type: Grant
    Filed: May 31, 1983
    Date of Patent: February 26, 1985
    Assignee: Rohm and Haas Company
    Inventors: Richard E. Baus, Graham Swift
  • Coated metal article
    Patent number: 4044190
    Abstract: Polymeric materials which comprise a hydroxyalkyl ester of acrylic acid or methacrylic acid, a monoethylenically .alpha.,.beta.-unsaturated carboxylic acid, and an alkyl ester or esters of acrylic and/or methacrylic acid are partially neutralized, isolated, and powdered to give useful powder coating compositions. The composition may be utilized for coating metallic articles.
