  • Publication number: 20220325019
    Abstract: A method of controlling long chain branching in an ethylene-based polymer includes polymerizing ethylene with one or more optional monomers to form an ethylene-based polymer, and controlling a degree of long chain branching (LCB) in the ethylene-based polymer. The degree of LCB ranges from 0.1 per 1000 carbon atoms in the polymer backbone to 10 per 1000 carbon atoms in the polymer backbone, as measured by 13CNMR. The degree of LCB is controlled by adding one or more branched vinyl ester to the polymerizing step in an amount ranging from 0.01 mol % to 5.0 mol %, relative to total monomer content. A polymer composition contains the ethylene-based polymer. An article includes the polymer composition containing the ethylene-based polymer.

  • Patent number: 11466745
    Abstract: An apparatus for suppressing oscillations of an oscillating body includes a magnetic base and a magnetic stabilizing mass pivotably coupled to the magnetic base by a pivot assembly. The pivot assembly defines a pivot axis about which the magnetic stabilizing mass is pivotable, relative to the magnetic base, between a first position and a second position. The magnetic stabilizing mass has an equilibrium position between the first position and the second position. The magnetic base produces magnetic fields that magnetically repel the magnetic stabilizing mass away from the first position at least when the magnetic stabilizing mass is offset from the equilibrium position toward the first position, and that magnetically repel the magnetic stabilizing mass away from the second position at least when the magnetic stabilizing mass is offset from the equilibrium position toward the second position.
