  • Plasma assisted grafting of maleic anhydride to polyolefins
    Patent number: 5612097
    Abstract: A method for grafting maleic anhydride groups to the surface of polyolefins s described. The method uses an excited inert gas phase species in contact with the polyolefin and solid maleic anhydride. The surface functionality is identified by X-ray photoelectron spectroscopy and transmission Fourier transform infrared spectroscopy. The modified polyolefin has an increased ability to form a thermal bond with metals, including aluminum.

  • Modification of polymer surfaces by two-step reactions
    Patent number: 5147678
    Abstract: Improved modification of polymer surfaces is achieved by two-step reactions on polymer surfaces, particularly where at least one of the steps is a "downstream" or remote plasma treatment. For example, polymers may be treated with various combinations of the following: (1) downstream nitrogen plasma treatment; (2) ozone treatment; (3) corona discharge treatment; (4) downstream oxygen plasma treatment; or (5) downstream hydrogen plasma treatment.
