  • Patent number: 7625955
    Abstract: A porous article which is formed from a polymeric material, in which characteristics of the surface of the article provided by the polymeric material are modified by having grafted to it chains of polymerized vinyl monomer units, in which the chains each comprise a number of units of a first vinyl monomer and include a unit of a second vinyl monomer which is different from the first vinyl monomer. Preferably, the ratio of the number of units of the first vinyl monomer in each chain to the number of units of the second vinyl monomer is not more than about 60. When the number of second vinyl monomer units in each chain is one, the mean number of first vinyl monomer units in each chain will be not more than 60.

  • Patent number: 7622511
    Abstract: A method and kit for providing a tack-free artificial nail surface. The tack-free artificial nail surface may include an acrylic layer and a barrier layer. The acrylic layer may comprise an odorless monomer. The barrier layer may be of any material impervious to oxygen. The tack-free nail surface may be formed by application of the acrylic layer to a fingernail nail bed. The barrier layer may then be applied over the acrylic layer. The barrier layer blocks oxygen from the acrylic layer so that the acrylic layer may polymerize in the absence of oxygen.

  • Patent number: 7618565
    Abstract: Lipobeads (liposome-encapsulated hydrogels) combine properties of hydrogels and liposomes to create systems that are sensitive to environmental conditions and respond to changes in those conditions in a fast time scale. Lipobeads may be produced by polymerizing anchored or unanchored hydrogels within liposomes or by mixing anchored or unanchored hydrogels with liposomes. Giant lipobeads may be produced by shrinking unanchored nanogels in lipobeads and fusing the resulting lipobead aggregates, long-term aging of anchored or unanchored lipobeads, or mixing anchored or unanchored aggregated nanogels with liposomes. Poly(acrylamide), poly(N-isopropylacrylamide), and poly(N-isopropylacrylamide-co-1-vinylimidazole) lipobeads were produced and characterized.
