  • Patent number: 6524657
    Abstract: Aromatic aliphatic ether solvents, such as anisole, methylanisole, and phenetole, have been found useful in formulating coating solutions of polymeric dielectric materials and as a clean up solvent in the coating process. A process for forming a dielectric film on a substrate includes depositing a coating solution of a dielectric material in a formulation solvent onto a surface of the substrate and depositing an aromatic aliphatic ether solvent onto an edge portion of the surface of the substrate. The process is used to form films of dielectric materials including arylene ether dielectric polymers, hydridosiloxane resins, organohydridosiloxane resins, spin-on-glass materials, partially hydrolyzed and partially condensed alkoxysilane compositions which are cured to form a nanoporous dielectric silica material, and poly(perhydrido)silazanes.

  • Patent number: 6514432
    Abstract: The template-guided synthesis of water-soluble, chiral conducting polymer complexes is described. Synthesis of water-soluble polyaniline complexes is achieved by carefully controlling the experimental parameters such as; acid concentration, ionic strength, monomer/template ratio, total reagent concentration, and order of reagent addition. Chiral (helical) polyaniline complexes can be synthesized by addition of a chiral inducing agent (chiral acid) prior to polymerization, and the polyaniline helix can be controlled by the addition of the (+) or (−) form of the chiral acid. Moreover the quantity of chiral acid and the salt content has a significant impact on the degree of chirality in the final polymer complexes. The polyaniline and the template have been found to be mixed at the molecular level which results in chiral complexes that are robust through repeated doping and dedoping cycles.

    Abstract: Aromatic aliphatic ether solvents, such as anisole, methylanisole, and phenetole, have been found useful in formulating coating solutions of polymeric dielectric materials and as a clean up solvent in the coating process. A process for forming a dielectric film on a substrate includes depositing a coating solution of a dielectric material in a formulation solvent onto a surface of the substrate and depositing an aromatic aliphatic ether solvent onto an edge portion of the surface of the substrate. The process is used to form films of dielectric materials including arylene ether dielectric polymers, hydridosiloxane resins, organohydridosiloxane resins, spin-on-glass materials, partially hydrolyzed and partially condensed alkoxysilane compositions which are cured to form a nanoporous dielectric silica material, and poly(perhydrido)silazanes.

  • Patent number: 6410680
    Abstract: A metal-dendrimer complex in which the metal active site is deep within the three-dimensional dendrimer construct, has superoxide dismutase-like activity. In particular embodiments the complex is a copper(II)-dendrimer complex and the dendrimer construct is a dendritic polypeptide, and the copper(II) is complexed with imidazole groups provided by histidine side groups within the dendritic construct. The dendrimer construct has a generally globular shape, and the branched chains nearer the surface are sufficiently densely packed to restrict the movement of larger biomolecules into the dendritic construct toward the metal active sites. Smaller molecules such as the superoxide anion (O2·−) move freely from the milieu into the dendritic complex and to the metal active sites, where the dismutation of superoxide to hydrogen peroxide is effected; and smaller molecules such as hydrogen peroxide move freely out from the dendritic complex to the milieu.

  • Patent number: 6403759
    Abstract: Disclosed are novel polymers derivatized with at least one —SNO group per 1200 atomic mass unit of the polymer. In one embodiment, the S-nitrosylated polymer has stabilized-S-nitrosyl groups. In another embodiment the S-nitrosylated polymer prepared by polymerizing a compound represented by the following structural formula: R is an organic radical. Each X′ is an independently chosen aliphatic group or substituted aliphatic group. Preferably, each X′ is the same and is a C2-C6 alkylene group, more preferably—CH2—, —CH2CH2—, —CH2CH2CH2— or —CH2CH2CH2CH2—. p and m are independently a positive integer such that p+m is greater than two. The polymers of the present invention can be used to coat medical devices to deliver nitric oxide in vivo to treatment sites.
