  • Publication number: 20240279401
    Abstract: A functionalized macromolecule includes a hydrogenated interpolymer portion, a non-hydrogenated polymer portion, and the radical of a functional coupling agent covalently bonded to and linking those portions. The functional group of the coupling agent exhibits interactivity with silica. The interpolymer can include vinyl aromatic mer and conjugated diene mer, with at least some of the latter, typically at least 50 mole percent, having been hydrogenated.
    Type: Application
    Filed: April 29, 2024
    Publication date: August 22, 2024
    Inventors: Yuan Liu, Ryan Hue, Laura S. Kocsis, Walter A. Salamant, Jeffrey M. Magistrelli

  • Publication number: 20230126418
    Abstract: Embodiments of the present disclosure are directed to functional polymers produced by copolymerization of at least one conjugated diolefin monomer and optionally one or more vinyl monomer, the functional polymer comprising at least one functional group having silica reactive moieties, wherein the functional copolymer has a degree of hydrogenation of from 40% to 98 mol % and a vinyl content of about 50% or less.

  • Publication number: 20210340306
    Abstract: Embodiments of the present disclosure are directed to functionalized copolymers produced by copolymerization of at least one conjugated diolefin monomer and at least one vinyl monomer, the functionalized copolymer including at least one functional group having silica reactive moieties, wherein the functionalized copolymer has a degree of hydrogenation of 75% to 98 mol % as measured using proton nuclear magnetic resonance spectroscopy (1H NMR). In one or more embodiments, the silane modifier may include an oxygen-containing moiety, wherein the oxygen atom of the oxygen-containing moiety may not be directly bonded with the silicon atom.
