    摘要： This invention relates to an improved polyvinylidene fluoride-based composition useful for forming a flexible, tack-free, nonflammable, substantially fluid resistant barrier film with substantially improved durability and skin-adhesion properties. The composition providing a long-lasting protective barrier film capable of disinfecting the skin surface of normally present microorganisms upon initial application, and said film imparting continuous and prolonged antimicrobial properties to the skin surface through sustained release of an encapsulated antimicrobial agent. The barrier film is further capable of remaining substantially adherent to the skin surface after prolonged exposure to biological fluids. A kit and methods of use for the composition are disclosed.

    摘要： The present invention involves a surface having a coating consisting essentially of a polymer that is soluble in or hydrolyzable by water. When the surface is immersed in an aqueous medium, the coating slowly dissipates such that biological fouling of the surface is prevented or inhibited. Substances adhering to the surface of the slowly dissipating polymer are removed as the polymer dissipates. This dissipation may result from slow hydrolysis of the polymer, particularly if the polymer is a polyester or polyanhydride. Preferred polyesters include polylactide and polyglycolide. Polymers soluble in water include polyvinyl alcohol and polyethylene glycol. Such solubility must be sufficiently slow such that the surfaces may be coated and the water-soluble polymer remains for a long period of time and is slowly dissipated into solution. Such dissipation from the surface removes adherent substances. The adherent substances may be bacteria, fungi, biomolecules or multicellular organisms. The surfaces treated include polyvinylchloride, other plastics, elastomers, metals or ceramics.

    摘要： The invention provides a denture liner composition for a composite denture based on a phosphonitrilic fluoroelastomer (poly(fluoroalkoxy)phosphazene) curable at atmospheric pressure at temperatures of 100.degree. C. or less, conveniently by immersing the packed denture flask in a water bath at the appropriate temperature. The composition includes filler materials for increasing the hardness of the cured liner, interpenetrating polymers for increasing firmness and bond strength, and cross-linking agents for increasing the tensile strength and bond strength of the cured liner. The composite denture is preferably prepared in a one-step process wherein the liner composition material of a single firmness is cured in situ with the denture base material. Alternatively, a firm liner material may be cured at the periphery of the denture and a softer liner material cured at the center, in order to provide a firm elastic liner where adjustments must be made by grinding and where the patient's soft tissues must be displaced, and a soft elastic liner over the bony anatomy of the patient where stresses from chewing are most concentrated and the soft tissues are thin.
