  • Patent number: 8703902
    Abstract: Polymerizable ionic liquid monomers and their corresponding polymers (poly(ionic liquid)s) are created and found to exhibit high absorption of radio frequency electromagnetic radiation, particularly in the microwave and radar bands. These materials are useful for coating objects to make them less reflective of radio frequency radiation and for making objects that absorb radio frequency radiation and are of minimal reflectivity to radio frequency radiation. Free-radical and condensation polymerization approaches are used in the preparation of the poly(ionic liquids).

  • Publication number: 20140087441
    Abstract: The invention discloses a novel application of fibrinogen-420 and its active domain (alpha EC domain), and a separate alpha EC domain protein has the same or similar function with fibrinogen-420. Fibrinogen-420 and its active domain can be widely used in inhibiting protein aggregation, helping protein refolding, drugs which can prevent and/or treat protein conformation disease, detecting denatured protein in quality control and protect protein from denaturation.

  • Publication number: 20120003177
    Abstract: Curcumin, a polyphenol extracted from the rhizome turmeric, has been polymerized to produce a polymer material having a backbone of one or more repeating structural units, at least one of which comprises a curcumin monomer residue. These curcumin-containing polymers have a wide range of pharmacological activities, including, among others antitumor, antioxidant, antiinflammatory, antithrombotic and antibacterial activities. Certain species of these polymers have exhibited remarkable antitumor activity. Water-soluble curcumin derivatives and their use as prodrugs and prodrug carriers are also disclosed.

  • Patent number: 7994087
    Abstract: A class of catalysts with unusually high activity for polymerizing vinyl monomers such as acrylates, methacrylates and styrene is described. The catalysts consists of a metal halide such as CuBr and FeBr2 ligated with multidentate amine-based ligands, for example N,N,N?,N?-tetra[(2-pyridal)methyl]ethylenediamine, and additives. The additives, which are tertiary amine compounds, can greatly increase the catalytic activity. The complex is capable of catalyzing a living polymerization reaction at a concentration of the complex below about 0.1 mol %.

  • Publication number: 20090156771
    Abstract: Disclosed are new, highly active and versatile atom transfer radical polymerization (ATRP) catalysts. These catalysts catalyze ATRP for acrylates, methacrylates, and styrenes at surprisingly low concentrations. These catalysts mediated ATRP at a catalyst/initiator molar ratio at 0.005 and produced polymers with well-controlled molecular weights and low polydispersities. ATRP occurred even at a catalyst/initiator molar ratio as low as 0.001 with metal concentration in the produced polymers as low as 6-8 ppm. Amine-containing compounds, such as triethylamine, can significantly increase the catalyst activity of theses catalysts. The amine compounds can also used to the terminal halogen groups such as Br and Cl in the polymers prepared by ATRP.
