  • Polymer composites containing alkylene oxide copolymers
    Patent number: 6825273
    Abstract: Polymer composites comprising a water-insoluble polymer and a water-sensitive polymer are disclosed. The water-sensitive polymer is a copolymer polymerized from one or more alkylene oxide monomers and one or more epoxy-functional monomers. The polymer composites can be used in the manufacture of articles having enhanced lubricious-when-wet properties, e.g., wet-shaving devices, and medical devices, e.g., catheters. The articles can provide enhanced retention of lubricity after repeated uses.
    Type: Grant
    Filed: February 20, 2003
    Date of Patent: November 30, 2004
    Assignee: Union Carbide Chemicals & Plastics Technology Corporation
