  • Publication number: 20090149583
    Abstract: The present invention discloses a polymeric polyamine which can be produced by polymerizing polyoxyalkylene-amine and a linker. The linker can be anhydride, carboxylic acid, epoxy, isocyanate or poly(styrene-co-maleic anhydride) copolymers (SMA). The present invention also discloses a method for stabilizing the Ag nanoparticles with polymeric polyamine. The polymeric polyamine serving as a stabilizer or dispersant is mixed with a water solution of silver salt and then a reducer is provided to reduce the silver ions and form an organic or a water solution of Ag nanoparticles. Water or solvent of this solution can be further removed through a heating, freezing or decompression process, and thus solid content of the solution can be increased. The concentrated solution also can be diluted to obtain a stable dispersion without aggregation.

  • Publication number: 20090055994
    Abstract: Certain polyether- or polyester-based polyurethaneureas in dipping solutions of organic solvent at a concentration of, for example, 12 to 20%, are particularly suited for use in a mandrel-dipping process for producing thin-walled elastic articles, such as surgical gloves. Such dipping solutions can be easily prepared, for example, by dissolving yarn comprising the polyurethaneurea and without the need to utilize metal chlorides, such as lithium chloride, in the yarn dissolving procedure.

  • Patent number: 7408018
    Abstract: The invention provides elastomeric copolyester amides, elastomeric copolyester urethanes, and methods for making the same. The polymers are based on ?-amino acids and possess physical, chemical and biodegradation properties that render them suitable for use in the human body. The polymers are useful as carriers of drugs or other bioactive substances. The polymers can also be linked, intermixed, or a combination thereof, to one or more drugs. Additionally, the polymers can be used to coat stents, for example, to suppress restenosis. Furthermore, the biodegradation of the copolyester amides and copolyester urethanes allows for the delivery of essential ?-amino acids to sites in the body, for example, to facilitate wound repair of injured tissues.
