  • Patent number: 7687551
    Abstract: Adhesive compositions useful for laminating cellulosic substrates are formulated using an aqueous emulsion of a vinyl ester polymer such as polyvinyl acetate, one or more monomers or oligomers functionalized with (meth)acrylate groups, and a photoinitiator. The adhesive is cured by drying and exposing the adhesive to UV or visible light and is particularly useful for attaching clear films to cellulosic substrates such as paper and boxboard (e.g., in the manufacture of envelopes or folding cartons having windows).

  • 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.
