  • Patent number: 9522999
    Abstract: The present invention relates to a process for preparing a polymer latex that includes polymerizing one or more ethylenically unsaturated aromatic monomers and one or more conjugated diene monomers in the presence of a hydroperoxide chain transfer agent and sulfur-containing chain transfer agent, wherein the sulfur-containing chain transfer agent is added after the hydroperoxide chain transfer agent. It further relates to the polymer latex thus obtained, to a composition comprising the polymer latex and to the use of the polymer latex or polymer latex composition in a carpet backing, paper coating, or fiber fabric pre-impregnation process.
    Type: Grant
    Filed: August 23, 2012
    Date of Patent: December 20, 2016
    Assignee: TRINSEO EUROPE GMBH
    Inventors: Bernard Fouchet, Etienne Lazarus, Nicolas Tissier, Ursula Seiler, Donato Ventresca
  • Patent number: 8889784
    Abstract: There is provided a stable aqueous dispersion comprising (a) dispersed particles of one or more film-forming polymer that comprises 1% to 10% by weight, based on the solid weight of said polymer, of polymerized units of one or more functional monomer, wherein said functional monomer is selected from acid-functional monomers or amine-functional monomers or a mixture thereof, and (b) one or more multiglycidyl compound having 4 or more glycidyl groups per molecule.
    Type: Grant

  • Patent number: 8691937
    Abstract: A method of preparing a low odor polymer latex composition includes the step of polymerizing a monovinylidene monomer, such as styrene, and a conjugated diene, such as butadiene, in the presence of a linear alkyl thiol chain transfer agent. The resulting polymer latex is treated with an oxidizing agent to oxidize residual chain transfer agent to volatile decomposition products that are then removed by steam stripping.
