  • Halogen-free flame retardant pressure sensitive adhesive and tape
    Patent number: 10526515
    Abstract: A halogen-free flame retardant adhesive comprises an acrylic copolymer preparable by polymerization of monomers comprising a first monomer which comprises a low glass transition temperature (Tg) monomer, a second monomer which comprises a high Tg monomer, wherein at least one of the first and second monomers comprises a (meth)acrylate, and a phosphinate containing monomer.
    Type: Grant
    Filed: December 18, 2015
    Date of Patent: January 7, 2020
    Assignee: 3M Innovative Properties Company
    Inventors: Eumi Pyun, Dennis E. Vogel, Thu-Van Tran, Tabitha A. Clem, Haohao Lin, William H. Moser, Anthony R. Plepys, Richard B. Ross
  • Method for preparing (meth)acrylates of biobased alcohols and polymers thereof
    Patent number: 9908837
    Abstract: Polymers, particularly those used in pressure-sensitive adhesives, are prepared from a mixture of structural isomers of a secondary alkyl (meth)acrylate monomer. The mixture is made by dehydrating a biobased C2-C22 alcohol with a first acid catalyst using a continuous process to form a mixture of olefins, and reacting (meth)acrylic acid with at least some of the mixture of olefins in the presence of a second acid catalyst. The adhesives are characterized by exhibiting an overall balance of adhesive and cohesive characteristics, and containing biobased material.

  • Selective synthesis of 2-octyl acrylate by acid catalyzed esterification of 2-octanol and acrylic acid
    Patent number: 9604902
    Abstract: A method of making 2-octyl acrylate comprising reacting 2-octanol with acrylic acid in the presence of an acid catalyst and added water is described. The 2-octanol may be derived from renewable resources, such as castor oil. The method is efficient and provides selectivity for 2-octyl acrylate.
