  • Publication number: 20130220516
    Abstract: An underwater pelletizing method for pelletizing brittle hydrocarbon resins with low melt viscosity. A feed material comprising the hydrocarbon resin is formed into a melt, extruded through a die into a water bath below the Tg of the hydrocarbon resin to form a plurality of extrudates and cut adjacent the die surface to form a slurry of resin pellets. A graft monomer and/or other reactants, such as a hydrosilylation agent, may be introduced into the resin melt to chemically modify the hydrocarbon resin.

  • Patent number: 8460770
    Abstract: Polymer compositions comprise a (i) silane-functionalized polymer, e.g., a polyethylene grafted with vinyl triethoxy silane, (H) polyfunctional alcohol e.g., ?,?,??,??˜tetramethyl-I,3-benzenediethanol and, optionally, (iii) acid, e.g., an alkylated aryl disulfonic acid. The use of polyfunctional alcohols in the absence of a strong acid yields a light-crosslinking of the silane-functionalized polymer and this, in turn, provides a polymer melt with improved extensional properties such as elongational viscosity and melt strength. The use of a polyfunctional alcohol in combination with a blocked strong acid provides a slow rate of crosslinking during melt processing and a high degree of ultimate crosslinking after the polymer composition has been shaped or molded.

  • Patent number: 8461263
    Abstract: The present invention provides an end-modified diene copolymer having excellent compatibility with silica as a reinforcement material, and a preparation process thereof, in which the end-modified diene copolymer is prepared by preparing a living polymer of a conjugated diene monomer and/or a vinyl aromatic monomer, modifying the living polymer with a reactive organosiloxane compound, and then modifying the end of the living polymer, to which the organosiloxane compound has not been coupled, with an organosilane compound having various functional groups. When the end-modified diene copolymer is used as a rubber material in the manufacture of a silica tire, the dispersion of silica in the copolymer can be improved and the bonding strength between silica and the rubber can be significantly increased, thereby manufacturing a high-quality silica tire.

    Abstract: A method of preparing core-shell submicron spheres is disclosed. The method comprises steps hereafter. An emulsion containing a core monomer is heated to a temperature of 10° C. below its boiling point to the boiling point. A core forming step is performed by adding an initiator solution to the heated emulsion to form cores by polymerizing the core monomer. When the conversion of the above polymerization is 10% to 95%, a shell forming step is performed by adding a shell monomer into the emulsion, at a temperature of 50° C. below the emulsion's boiling point to the boiling point thereof, to form shells, respectively surrounding the cores, by polymerizing the shell monomer.
