  • Polymer latex with improved mechanical properties and process for preparing said polymer latex
    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
  • Crosslinkable polymer dispersion
    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.
