  • Patent number: 6884842
    Abstract: Synthetic polymer complements (SPCs) are provided, as well as methods for their synthesis and use. The SPCs may have surfaces that include functional groups that are complementary to surface sites of targets such as nanostructures or macromolecular targets, and may be capable of specifically interacting with such targets. The positions of the functional groups in one embodiment are stabilized by a polymer network. The SPCs are formed by contacting the target with a set of monomers which self-assemble on the target, and then are polymerized into a network to form the synthetic polymer complement. At least a portion of the surface of the resulting SPC thus may include an imprint of the target. The complex of the SPC and the target may be the desired product. Alternatively, the target is released, for example, by controllably expanding and contracting the crosslinked network. The SPC is isolated and used in many applications.

  • Patent number: 6803410
    Abstract: Cellulosic polymers, copolymers and grafts, are disclosed that adhere to fibers and surfaces during an aqueous treatment process. The cellulosic polymers having grafts and/or co-blocks are prepared using living-type free radical polymerization techniques, which provides control over the degree of substitution and graft/co-block composition and structure. These cellulosic polymers allow for the modification of fibers and surfaces to provide a desired effect.

  • Patent number: 6730722
    Abstract: The invention provides cross-linkable polymer powder compositions containing a) at least one water-soluble polyhydroxy compound; b) at least one boric acid complex compound which is of limited solubility in water that is, it has a water solubility of less than 10 g per liter at normal conditions; and optionally c) a water-soluble film-forming polymer consisting of one or more free-radical polymerizable, ethylenically unsaturated monomers. The compositions are useful as a constituent in adhesives, plaster, jointing mortars, paints and binders for coating compositions, textiles, paper and the like.
