  • Ethylene-methoxy polyethylene glycol methacrylate copolymers
    Patent number: 11203682
    Abstract: The copolymerization of ethylene (E) and methoxy polyethylene glycol methacrylate (MPEGMA) produces the copolymer co-E-MPEGMA. These copolymers are distinct from polyethylene, e.g., low density polyethylene (LDPE) grafted with MPEGMA, i.e., g-E-MPEGMA, and are useful in the preparation of insulation sheaths for medium, high and extra-high voltage cables. Such cables exhibit good water tree retardance.
    Type: Grant
    Filed: June 12, 2018
    Date of Patent: December 21, 2021
    Assignee: Dow Global Technologies LLC
    Inventors: Qian Gou, Manish Talreja, Bharat Chaudhary, John Osby
  • Process for making crosslinked cable insulation using high melt strength ethylene-based polymer made in a tubular reactor and optionally modified with a branching agent
    Patent number: 10844209
    Abstract: An insulated wire or cable is made by a process comprising the steps of: (A) extruding onto a covered or uncovered metal conductor or optical fiber a composition having a DF measured at 130° C. (60 Hz, 2 kV) or 120° C. (60 Hz, 8 kV) or 100° C. (60 Hz, 8 kV) of <0.5% and comprising: (1) a high melt strength ethylene-based polymer made in a tubular reactor, and (2) a peroxide, and (B) crosslinking the high melt strength ethylene-based polymer.
