    Abstract: A permselective graft polymer is disclosed that is formed by converting into intermediate reactive sites a portion of the cyano groups of a backbone polymer containing —CH2—CH(—C≡N)— units, and grafting polyalkylene oxide polymer chains to the backbone polymer through the reactive sites. Either the backbone polymer of a polymer resin or a permselective polymer membrane can be grafted. When a resin is used, it is formed into a permselective polymer membrane using known methods. The resulting permselective membrane can be formed into hollow fibers or flat sheets for the encapsulation of living cells. The encapsulated cells are then implanted into a patient in need of the biologically active factors produced by the cells. The permselective graft polymer membrane exhibits good molecular diffusion with minimal protein adsorption.

  • Patent number: 6031023
    Abstract: Novel white board dry erase ink compositions are provided which are comprised of poly(oxyalkylene) substituted colorants, volatile solvent vehicles, and binder resins. The binder resin is insoluble within the alcohol of the volatile vehicle; however, the degree of alkoxylation on the colorant aids in solubilizing the binder resin within the entire solution. Once the composition is transferred to a white board, the solvent evaporates, leaving the binder resin and colorant as a friable discontinuous film which is easily removed from the writing surface. The inventive composition has improved erasability, writability, stability within the marker stylus, and washability from skin and fabrics. Markers and methods of producing the ink composition are also provided.

  • Patent number: 5916968
    Abstract: A graft copolymer for use as an adhesive for drug delivery patches or dressings that is resistant to dissolution in the presence of skin penetration enhancers comprises copolymerized acrylic and, optionally, vinyl monomers, to form a backbone polymer, to which are grafted polymeric moieties that do not absorb greater than 3% by weight of a skin-penetration enhancer under thermodynamic equilibrium at 25.degree. C. if independently introduced into an excess of the enhancer. Preferably, the grafted polymers are selected from the classes of polybutylene, polysaccharide, poly(ethyleneoxide/propyleneoxide), and polyamide polymers, and specific grafted polymers will depend on the specific enhancers used in a particular drug delivery system.

  • Patent number: 5916969
    Abstract: A water-responsive, thermoplastic article is formed from a composition of matter comprising a blend of polyolefins and poly(ethylene oxide). A water-dispersible article can be made from a blend having from about 1 weight percent to about 35 weight percent polyolefin and from about 99 weight percent to about 65 weight percent of poly(ethylene oxide). The water responsiveness of the article can be varied by modifying the polyolefin and increasing the content of polyolefin in the blend upwards to about 55 weight percent. The compositional blends can be made into a flushable barrier film for use in a disposable absorbent article, such as a diaper or feminine pad, or can be used to make a water responsive tampon tube. A method of making the article comprises blending together the polyolefin and poly(ethylene oxide) under melt conditions and forming the article.

  • Patent number: 5912076
    Abstract: A thermoplastic film comprises a polyolefin, such as polyethylene, as a major constituent, poly(ethylene oxide) as a minor constituent and has a total of from about 0.1 weight percent to about 30 weight percent of monomer grafted to the polyolefin and the poly(ethylene oxide). The film exhibits an inverse phase morphology so that the poly(ethylene oxide) forms a continuous phase and the polyolefin forms a dispersed or discontinuous phase in the film. Desirably, the film can be used in disposable personal hygiene articles.
