  • Thermoplastic vulcanizates comprising propylene-based elastomers and methods for making the same
    Patent number: 10279527
    Abstract: Described herein are thermoplastic vulcanizates comprising propylene-based elastomers and methods for producing the same. The thermoplastic vulcanizates comprise rubber, at least 10 wt % of thermoplastic resin, from 1 to 9 wt % of propylene-based elastomer, oil, and at least 5 wt % of one or more fillers. The thermoplastic vulcanizates are made by a method where the propylene-based elastomer is introduced to the extrusion reactor before the curative is introduced to the extrusion reactor.

  • Underwater pelletizing method for low viscosity hydrocarbon resins
    Patent number: 9994664
    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.
