  • COPOLYMERIZATION PROCESS FOR FORMING A POLYETHYLENE COPOLYMER NANOCOMPOSITE
    Publication number: 20230357517
    Abstract: A method for producing a polyethylene nanocomposite by polymerizing ethylene in a polymerization mixture that contains a graphene-layered double hydroxide nanocomposite, a metallocene catalyst, an alkylaluminoxane co-catalyst, and an organic solvent to form a polyethylene nanocomposite in which the graphene-layered double hydroxide nanocomposite is dispersed in a matrix of polyethylene and wherein the graphene-layered double hydroxide nanocomposite contains 1 to 7 wt.% graphene relative to a total weight of the graphene-layered double hydroxide nanocomposite.
    Type: Application
    Filed: July 10, 2023
    Publication date: November 9, 2023
    Applicant: KING FAHD UNIVERSITY OF PETROLEUM AND MINERALS
    Inventors: Mamdouh A. AL-HARTHI, Muhammad DAUD
