  • Method for producing phosphonate-modified silicones
    Publication number: 20070049718
    Abstract: Phosphonate-functional organosilicon compounds in which the phosphonate ester group is linked to silicon by an Si—C—P linkage are prepared rapidly and in high yield by the hydrolysis and polycondensation of phosphonate-functional alkoxysilanes with water.
    Type: Application
    Filed: July 1, 2004
    Publication date: March 1, 2007
    Applicant: CONSORTIUM FUER ELEKTROCHEMISCHE INDUSTRIE GMBH
    Inventors: Oliver Schafer, Hans-Joachim Luckas, Sandra Rachl
  • Novel organosilicon compounds and a method for their production
    Publication number: 20060247409
    Abstract: Phosphorous-modified organosilicon compounds containing silicon-bound methoxy groups and a methylene spacer linking silicon to the phosphorous moiety are easily prepared in high yield and exhibit excellent hydrolysis rates. The compounds are useful, inter alia, as stabilizers in anti-freeze compositions, as cohydrolysis reactants in preparation of modified silicone resins, and in coatings.
