  • Patent number: 5660178
    Abstract: A hydrophilic, pressure sensitive adhesive of a poly(ethylene oxide) derived network plasticized with an essentially non-volatile, polar plasticizer present in an amount sufficient to form a cohesive, pressure sensitive adhesive. The polymeric network is prepared from an oligomeric precursor comprising difunctional poly(ethylene glycol) moieties which have been end-capped with ethylenically unsaturation. The adhesive is useful as a biomedical adhesive for transmitting or receiving electrical signals as a component of a biomedical electrode. The adhesive is also useful as a drug delivery device to deliver pharmaceuticals or other active ingredients to or through mammalian skin. The adhesive is also useful as a component in a skin covering for protecting mammalian skin or mammalian skin openings with antimicrobial agents. A method of preparation of the adhesive is also disclosed.
    Type: Grant
    Filed: January 5, 1996
    Date of Patent: August 26, 1997
    Assignee: Minnesota Mining and Manufacturing Company
