  • Patent number: 11097307
    Abstract: The present invention relates to a method comprising the steps of: a) contacting an acrylate monomer, a carboxylic acid monomer, and a chain transfer agent under free radical polymerization conditions to form a solution of a polymer having an Mn in the range of from 5,000 to 50,000 Daltons; b) contacting the solution with a base and an ethylenically unsaturated glycidyl functionalized monomer to form a solution of an ethylenically unsaturated acrylate polymer; c) contacting the solution of the ethylenically unsaturated functionalized acrylate polymer with water to form an aqueous dispersion of ethylenically unsaturated functionalized acrylate polymers; and d) removing the organic solvent. The method of the present invention provides a composition suitable for use as a UV curable coating that achieves an excellent balance of hardness, flexibility, and warmth with less reliance on costly MFAs.
    Type: Grant
    Filed: June 5, 2019
    Date of Patent: August 24, 2021
    Assignees: Dow Global Technologies LLC., Rohm and Haas Company

  • Patent number: 10961410
    Abstract: The present invention relates to a method comprising an aqueous dispersion of polymer particles having a backbone comprising structural units of an acrylate monomer and a carboxylic acid monomer, wherein a portion of the structural units of the carboxylic acid monomer are functionalized with glycidyl methacrylate, wherein the glycidyl methacrylate functionalized polymer particles have a number average molecular weight in the range of 5,000 to 50,000 Daltons. The composition of the present invention provides a UV curable coating that achieves an excellent balance of hardness and flexibility, with less reliance on the use of multifunctional acrylates.
