    Abstract: An electrode providing electrical contact with a patient's skin includes a conductive member adapted for connection to an external electrical apparatus and a non-liquid water containing film for electrically interfacing to said patient's skin, the non-liquid film being electrically and mechanically connected to said conductive member. The non-liquid water containing film includes an electrically conductive organic polymer plasticized with a polyhydric alcohol with said organic polymer being derived from a monomeric mixture comprising from about 2 to 30 pph acrylic acid, 2 to 30 pph of a glycolvinylether and 0.01 to 1.5 pph of a crosslinking agent. Preferably the polyhydric alcohol is glycerol.

  • Patent number: 7538145
    Abstract: The phase change, curable composition comprises curable monomer, photoinitiator that initiates polymerization of the curable monomer, and phase change agent that provides the composition with an increase in viscosity of at least four orders of magnitude, from a first temperature, the first temperature being from 50° C. to 130° C., to a second temperature, the second temperature being from 0° C. to 70° C., wherein the second temperature is at least 10° C. below the first temperature. A coating over an image may be applied by providing a composition comprising curable monomer at a first temperature; applying the composition over the image, the image being at a second temperature; and exposing the composition to radiation to initiate polymerization of the curable monomer. In this process, the composition has a viscosity at the second temperature that is at least four orders of magnitude greater than its viscosity at the first temperature.

  • Patent number: 7521486
    Abstract: Fluoropolymers are made by admixing tetrafluoroethylene, hexfluoropropylene, and vinylidene fluoride; reacting the reaction admixture to generate a set of fluoropolymeric oligomers; irradiating the fluoropolymeric oligomeric precursor admixture (preferably with electron beam radiation) to form free radical sites on individual fluoropolymeric oligomers of the set and generate thereby a set of free radical oligomer derivatives in the fluoropolymeric oligomeric precursor admixture; and reacting the fluoropolymeric oligomeric precursor admixture to derive the fluoropolymer compound from the free radical oligomer derivatives. In a second approach, fluoropolymers are made by admixing tetrafluoroethylene, hexfluoropropylene, and vinylidene fluoride and irradiating the admixture.
