  • Bioactive Hydrogel
    Publication number: 20140377330
    Abstract: The invention relates to a bioactive hydrogel as a hybrid material of heparin and star-branched polyethylene glycol with functionalized end groups, wherein the heparin is bound directly by reaction of the carboxyl groups activated with 1-ethyl-3-(3-dimethylaminopropyl) carbodiimides/N-hydroxysulfosuccinimide (EDC/s-NHS) with the terminal amino groups of the polyethylene glycol covalently by amide bonds.
    Type: Application
    Filed: September 8, 2014
    Publication date: December 25, 2014
    Inventors: Carsten Werner, Uwe Freudenberg, Dorit Meinhold, Marie-Francoise Gouzy, Petra Welzel

  • Polysilane-Polycarbosilane Copolymer Solutions and Oxygen-Depleted Ceramic Moulded Bodies Prepared Therefrom with Compositions Similar to that of Sic
    Publication number: 20080207430
    Abstract: The present invention pertains to a method for producing a polysilane-polycarbosilane copolymer solution, which comprises the preparation of a polysilane, obtained by the disproportionation of a methylchlorodisilane or a mixture of methylchlorodisilanes of the formula Si2MenCl6-n with a Lewis base as the catalyst, a subsequent thermal crosslinking of the polysilane to form an infusible polysilane-polycarbosilane copolymer that is soluble in inert solvents, as well as the production of said solution by the dissolution of the polysilane-polycarbosilane copolymer in an inert solvent. In addition, the present invention also pertains to a method for producing oxygen-depleted ceramic fibers and other molded bodies having a composition similar to that of SiC.
