  • Patent number: 7737131
    Abstract: The present invention relates to a biologically active functionalized electrospun matrix to permit immobilization and long-term delivery of biologically active agents. In particular the invention relates to a functionalized polymer matrix comprising a matrix polymer, a compatibilizing polymer and a biomolecule or other small functioning molecule. In certain aspects the electrospun polymer fibers comprise at least one biologically active molecule functionalized with low molecular weight heparin. Examples of active molecules that may be used with the multicomponent polymer of the invention include, for example, a drug, a biopolymer, for example a growth factor, a protein, a peptide, a nucleotide, a polysaccharide, a biological macromolecule or the like. The invention is further directed to the formation of functionalized crosslinked matrices, such as hydrogels, that include at least one functionalized compatibilizing polymer capable of assembly.

  • Patent number: 6867255
    Abstract: A nanocomposite made with an inorganic layered material and a star-shaped polystyrene that can be blended with normal linear polystyrene is disclosed. The inorganic layered material can have an exfoliated structure, substantially exfoliated, or intercalated structure. The exfoliated structure can result in significantly improved physical properties, even with only a very low content of clay. The invention is also directed to a process that can be used to make the compositions of the present invention. In one embodiment, a physical mixture of clay and star polymer is prepared and then the mixture is heated for several hours, preferably under high-shear mixing, to increase the rate of exfoliation, after which mostly inexpensive commodity linear polystyrene polymer completes the composition.
