  • Processes for enhancing flame retardance and chemical resistance of polymers
    Patent number: 9963545
    Abstract: Processes for increasing the chemical resistance of a surface of a formed article are disclosed. The formed article is produced from a polymeric composition comprising a photoactive additive containing photoactive groups derived from a monofunctional benzophenone. The surface of the formed article is then exposed to ultraviolet light to cause crosslinking of the photoactive additive and produce a crosslinked surface. The crosslinking enhances the chemical resistance of the surface. Various means for controlling the depth of the crosslinking are also discussed.
    Type: Grant
    Filed: January 28, 2015
    Date of Patent: May 8, 2018
    Assignee: SABIC GLOBAL TECHNOLOGIES B.V.
    Inventors: Jean-Francois Morizur, Paul Dean Sybert, Amanda Marie Flores, Peter Johnson, Andrew Frazee, Thomas L. Evans

  • Processes for enhancing flame retardance and chemical resistance of polymers
    Patent number: 9587078
    Abstract: Processes for increasing the chemical resistance of a surface of a formed product are disclosed. The formed product is produced from a polymeric composition comprising a photoactive additive containing photoactive groups derived from a dihydroxybenzophenone. The surface of the formed product is then exposed to ultraviolet light to cause crosslinking of the photoactive additive and produce a crosslinked surface. The crosslinking enhances the chemical resistance of the surface. Various means for controlling the depth of the crosslinking are also discussed.
