  • Patent number: 10538654
    Abstract: This disclosure relates to a continuous solution three reactor polymerization process. Process solvent, ethylene, optional comonomers, optional hydrogen and a single site catalyst system are injected into a first and second reactor configured in parallel to one another. A third reactor receives effluent from the first reactor, the second reactor, or a combination of the first and second reactors. Fresh monomer is feed to the third reactor for further polymerization and to give a final polyethylene product.

  • Patent number: 10508188
    Abstract: High-melting antimicrobial polymer fibers and antimicrobial fabrics comprising such fibers are prepared by preparing a masterbatch of polymer pellets (e.g., PET), silver and copper salts, and a compounding agent which provides free flowing polymer pellets which can be prepared in advance, with a long shelf life. Polymer masterbatches prepared by the methods of the invention can produce limited color or off-white antimicrobial fibers and fabrics using conventional melt spinning manufacturing methods. Fabrics incorporating fibers of the present invention are potent inhibitors of Athlete's foot fungi, gram negative and gram positive bacteria, and drug resistant pathogens.
