  • Method for grafting preformed hydrophilic polymers onto hydrophobic polymer substrates
    Patent number: 5527618
    Abstract: Coatings of hydrophilic organic polymers such as polyvinyl alcohol are grafted to substrates formed from hydrophobic organic polymers and polyorganosiloxanes by exposing the surface of the substrate to an aqueous solution of the hydrophilic polymer in the presence of a solubilized compound of tetravalent cerium that preferably contains hydroxyl or amino groups as ligands.
    Type: Grant
    Filed: April 4, 1995
    Date of Patent: June 18, 1996
    Assignee: Mizu Systems, Inc.
    Inventors: Daniel Graiver, Toshiyuki Okada, Samir D. Serrano
