  • Fluorinated PVC copolymer compositions for increased ultraviolet protection
    Patent number: 11945890
    Abstract: Fluorinated compositions include a fluorinated copolymer formed from a fluorine-containing monomer and vinyl chloride, the fluorine-containing monomer in an amount of from 0.5 weight % to 10.0 weight % based on a combined weight % of fluorine-containing monomer and vinyl chloride. Methods of making a fluorinated copolymer are further provided. Ultraviolet-protective films formed from a mixture including a fluorinated copolymer are further provided.
    Type: Grant
    Filed: March 23, 2022
    Date of Patent: April 2, 2024
    Assignee: Mexichem Specialty Resins Inc.
