  • Patent number: 8469037
    Abstract: A pre-portioned moist product comprising a portion of plant material and a coating is disclosed. Preferably, the plant material comprises tobacco. The coating includes a soluble, non-cross-linkable component and an cross-linkable component which becomes substantially water-insoluble upon crosslinking. The soluble component of the coating dissolves upon placement in the mouth, while the insoluble component disintegrates and/or loses structural integrity once the soluble component has dissolved to release and disperse the plant material in the user's mouth.

  • Publication number: 20030144441
    Abstract: A copper-mediated process for the synthesis of random copolymers of methyl acrylate with non-polarolefins, ranging from ethene to 1-octene, norbornene and norbornene derivatives, and capable of synthesizing copolymers having greater than 5% incorporation of the olefin, as well as copolymers synthesized using the process are described. The process displays many of the characteristics of a living polymerization process: the polydispersities of the copolymers obtained are less than about 1.7, preferably from about 1.1 to about 1.4, and it is possible to synthesize novel block terpolymers of methyl acrylate with olefins by the sequential addition of the latter monomers.
