  • Ring-opened azlactone initiators for atom transfer radical polymerization
    Publication number: 20050159569
    Abstract: Initiators for atom transfer radical polymerizations are described. The initiators have an azlactone or ring-opened azlactone moiety to provide telechelic (co)polymers.
    Type: Application
    Filed: March 16, 2005
    Publication date: July 21, 2005
    Inventors: Duane Fansler, Kevin Lewandowski, Babu Gaddam, Steven Heilmann, Larry Krepski, Stephen Roscoe, Michael Wendland
  • Reactive hydrophilic oligomers
    Publication number: 20050131148
    Abstract: Hydrophilic compositions are described, which are prepared from a first component oligomer containing pendent hydrophilic groups and pendent reactive functional groups capable of reaction at effective rates (at normal processing temperatures), with a co-reactive second component possessing functionality that is complementary to that of the first oligomer. The compositions may be used as in preparation of hydrophilic gel coatings or layers for medical devices.

  • Reactive hydrophilic oligomers
    Publication number: 20050070688
    Abstract: Hydrophilic compositions are described, which are prepared from a first oligomer containing pendent polymerizable groups and pendent hydrophilic groups, crosslinked with a co-reactive second component oligomer possessing polymerizable groups. The compositions may be used as in preparation of hydrophilic gel coatings or layers for medical devices.
