    Abstract: The synthesis of a polyoxometalate-loaded epoxy uses a one-step cure by applying an external stimulus to release the acid from the polyoxometalate and thereby catalyze the cure reaction of the epoxy resin. Such polyoxometalate-loaded epoxy composites afford the cured epoxy unique properties imparted by the intrinsic properties of the polyoxometalate. For example, polyoxometalate-loaded epoxy composites can be used as corrosion resistant epoxy coatings, for encapsulation of electronics with improved dielectric properties, and for structural applications with improved mechanical properties.

    Abstract: A new class of poly(beta-amino alcohols) (PBAAs) has been prepared using combinatorial polymerization. The inventive PBAAs may be used in biotechnology and biomedical applications as coatings (such as coatings of films or multilayer films for medical devices or implants), additives, materials, excipients, non-biofouling agents, micropatterning agents, and cellular encapsulation agents. When used as surface coatings, these PBAAs elicited different levels of inflammation, both in vitro and in vivo, depending on their chemical structures. The large chemical diversity of this class of materials allowed us to identify polymer coatings that inhibit macrophage activation in vitro. Furthermore, these coatings reduce the recruitment of inflammatory cells, and reduce fibrosis, following the subcutaneous implantation of carboxylated polystyrene microparticles. These polymers may be used to form polyelectrolyte complex capsules for cell encapsulation.

  • Patent number: 7468454
    Abstract: The present invention relates to a process for preparing amino-functional polyurethane prepolymers by a) preparing an NCO-functional polyurethane prepolymer by reacting an excess of one or more di- and/or polyisocyanates with at least one isocyanate-reactive compound having a functionality of at least 1.5, b) reacting the free NCO groups of the resulting polyurethane prepolymer with at least one compound containing one or more silanol groups to obtain the corresponding silylurethanes, and then c) converting the silylurethanes to amino-functional polyurethane prepolymers by hydrolysis and/or alcoholysis with decarboxylation. The present invention also relates coatings, adhesives, sealants, casting compounds or moldings obtained from these amino-functional polyurethene prepolymers.

  • Publication number: 20080269420
    Abstract: The shape memory polymers disclosed are a reaction product of at least one reagent containing two active amino-hydrogen or two active phenolic-hydrogen with at least one multifunctional cross linking reagent which contains at least three or more active amino- or phenolic-hydrogen or is a reagent containing at least three glycidyl ether moieties which is then further mixed with at least one diglycidyl ether reagent whereupon the resulting mixture is cured and has a glass transition temperature higher than 00C. This reaction creates crosslinking between the monomers and polymers such that during polymerization they form a crosslinked thermoset network.

  • Patent number: 7230068
    Abstract: The invention provides water-soluble compounds that include a polymer and at least one terminal azide or acetylene moiety. Also provided are highly efficient methods for the selective modification of proteins with PEG derivatives, which involves the selective incorporation of non-genetically encoded amino acids, e.g., those amino acids containing an azide or acetylene moiety, into proteins in response to a selector codon and the subsequent modification of those amino acids with a suitably reactive PEG derivative.

  • Patent number: 7037399
    Abstract: A curable underfill encapsulant composition that is applied directly onto semiconductor wafers before the wafers are diced into individual chips. The composition comprises a thermally curable epoxy resin, a solvent, an imidazole-anhydride curing agent, fluxing agents, and optionally, wetting agents. Various other additives, such as defoaming agents, adhesion promoters, flow additives and rheology modifiers may also be added as desired. The underfill encapsulant is B-stageable to provide a coating on the wafer that is smooth, non-tacky and will allow the wafer to be cleanly diced into individual chips. A method for producing an electronic package containing the B-stageable material may also utilize an unfilled liquid curable fluxing material on the substrate to which the chip is to be attached.

  • Patent number: 7026440
    Abstract: The present invention is directed to branched reactive water-soluble polymers comprising at least two polymer arms, such as poly(ethylene glycol), attached to a central aliphatic hydrocarbon core molecule through heteroatom linkages. The branched polymers bear at least one functional group for reacting with a biologically active agent to form a biologically active conjugate. The functional group of the branched polymer can be directly attached to the aliphatic hydrocarbon core or via an intervening linkage, such as a heteroatom, -alkylene-, —O-alkylene-O—, -alkylene-O-alkylene-, -aryl-O—, —O-aryl-, (—O-alkylene-)m, or (-alkylene-O—)m linkage, wherein m is 1–10.
