  • 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.
