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.

Abstract: A polymerized microemulsion pressure sensitive adhesive composition is described. The composition has peel adhesion of at least 3 Newtons/100 mm as measured according to a PSTC-1 Test. The composition preferably has a bicontinuous structure of a continuous phase of a hydrophobic pressure sensitive adhesive polymer and a continuous phase of a hydrophilic polymer. The bulk properties of both polymers are retained in the bicontinuous structure. The composition is prepared from a microemulsion comprising a free-radically ethylenically unsaturated polar amphiphilic or hydrophilic monomer or oligomer in the aqueous phase, a free-radically ethylenically unsaturated hydrophobic monomer, having a glass transition temperature suitable for forming a pressure sensitive adhesive, in the oil phase, water, and surfactant. Uses for the pressure sensitive adhesive composition include biomedical articles, such as biomedical electrodes, medical skin coverings, and pharmaceutical delivery devices, and industrial articles, such as zinc/adhesive tapes used for cathodic protection of rebars embedded in concrete.

Abstract: A multi-layer article comprising a substrate and a dehydrofluorinated fluoropolymer, wherein the dehydrofluorinated polymer contains substantially no grafted adhesion-promoting groups, and the dehydrofluorinated fluoropolymer contains sufficient carbon-carbon unsaturation to increase the adhesion between the dehydrofluorinated fluoropolymer and the hydrocarbon substrate.

Abstract: An absorbent dressing that includes a transparent, elastomeric, body fluid-absorbing composition that is essentially free of hydrocolloidal gel particles. The composition includes the reaction product of: (a) 20 to 80 parts by weight of an acrylic or methacrylic acid ester of a non-tertiary alcohol having between 4 and 14 carbon atoms, inclusive; (b) 30 to 60 parts by weight of a hydrophilic, ethylenically unsatured monomer; and (c) 5 to 25 parts by weight of a polar, ethylenically unsaturated monomer different from the hydrophilic, ethylenically unsaturated monomer. The composition is capable of absorbing moderate to heavy amounts of body fluids, while retaining its structural integrity and transparency.
