  • Methods of making shaped polymeric materials
    Patent number: 8696975
    Abstract: The present disclosure describes methods for making shaped polymeric materials. Methods are provided for making shaped polymeric materials from a precursor composition that contains a polar solvent and a polymerizable material that is miscible with the polar solvent. The precursor composition is at least partially polymerized in a mold.
    Type: Grant
    Filed: December 8, 2008
    Date of Patent: April 15, 2014
    Assignee: 3M Innovative Properties Company
    Inventors: Caroline M. Ylitalo, Robin E. Wright, Matthew T. Scholz, Narina Y. Stepanova, Jessica M. Buchholz
  • Polymeric beads and methods of making polymeric beads
    Patent number: 8513322
    Abstract: Polymeric beads and methods of making the polymeric beads are described. The polymeric beads are crosslinked hydrogels or dried hydrogels. The polymeric beads are formed from droplets of a precursor composition that are exposed to radiation. The droplets are totally surrounded by a gas phase. The precursor composition contains a polar solvent and a polymerizable material miscible in the polar solvent. The polymerizable material has an average number of ethylenically unsaturated groups per monomer molecule equal to at least 1.2.
    Type: Grant

    Date of Patent: August 20, 2013
    Assignee: 3M Innovative Properties Company
    Inventors: Robin E. Wright, Mahfuza B. Ali, Jessica M. Buchholz, Louis C. Haddad, Linda K. M. Olson, Matthew T. Scholz, Narina Y. Stepanova, Michael J. Svarovsky, Richard L. Walter, Caroline M. Ylitalo, Diane R. Wolk, Yifan Zhang
  • Polymeric fibers and methods of making
    Patent number: 7939578
    Abstract: Polymeric fibers and methods of making the polymeric fibers are described. The polymeric fibers are crosslinked hydrogels or dried hydrogels that are prepared from a precursor composition that contains polymerizable material having an average number of ethylenically unsaturated groups per monomer molecule greater than 1.0. The polymeric fibers can contain an optional active agent.
