  • Chromatography column with carbonaceous adsorbents from pyrolyzed polysulfonated polymers
    Patent number: 5104530
    Abstract: Carbonaceous adsorbent particles having multimodal pore size, including micropores and macropores, with improved adsorptive and separative properties, are prepared by partial pyrolysis of polysulfonated macroporous precursor resins, said resins being in turn derived from macroporous poly(vinylaromatic) resins. The particles may be further treated by activating with reactive gases or by functionalization.
    Type: Grant
    Filed: May 4, 1990
    Date of Patent: April 14, 1992
    Inventors: Stephen G. Maroldo, William R. Betz, Noah Borenstein
