ABSTRACT:
A hydrophilic, pressure-sensitive adhesive composition prepared by irradiating solid poly(N-vinyl lactam) with ionizing radiation to crosslink the poly(N-vinyl lactam) and thereafter mixing the radiation-crosslinked poly(N-vinyl lactam) with essentially unirradiated plasticizer in an amount sufficient to form a cohesive, pressure-sensitive adhesive composition. The composition is useful as a biomedical adhesive for transmitting or receiving electrical signals as a component of a biomedical electrode. The composition is also useful as a drug delivery device to deliver pharmaceuticals or other active ingredients to or through mammalian skin. The composition 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 composition is also disclosed.
