Hydrophilic pressure sensitive adhesives
First Claim
1. A hydrophilic, pressure sensitive adhesive comprising:
- 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, wherein the network is prepared from an oligomeric precursor comprising difunctional poly(ethylene glycol) moieties which have been end-capped with ethylenically unsaturated functionality and wherein the amount of oligomeric precursor in the pressure sensitive adhesive ranges from about 4 to 60 weight percent of the pressure sensitive adhesive.

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.
