  • Process for making improved chromatography media and method of use
    Patent number: 9067195
    Abstract: The present invention further is directed to the process for making a macroporous polymeric media with covalently bonded quaternary ammonium polymer chains. The media can be applied for chromatographic purification, resulting in porous substrates having improved protein binding capacity and resin selectivity, as well as methods relating to making and using the same.
    Type: Grant
    Filed: July 26, 2011
    Date of Patent: June 30, 2015
    Assignee: Rohm and Haas Company
    Inventors: Martin J. Deetz, John J. Maikner

  • PROCESS FOR MAKING IMPROVED CHROMATOGRAPHY MEDIA AND METHOD OF USE
    Publication number: 20120024791
    Abstract: The present invention further is directed to the improved process for making by free radical polymerization a monodisperse, macroporous polymeric media with covalently bonded polymer chains. The media can be applied for chromatographic purification, resulting in polymer supports having improved protein binding capacity and resin selectivity, as well as methods relating to making and using the same.
