  • Method for producing hybrid particles
    Patent number: 8765889
    Abstract: The invention relates to a method for producing hybrid-particles containing polymer and SiO2-particles, wherein a) in a first polymerization step in aqueous medium a water-insoluble phase containing one or more monomeric and colloidal SiO2-particles having an average particle diameter of 1 to 150 nm are polymerized, and b) in a second polymerization step in aqueous medium one or more monomers are polymerized in the presence of the polymer obtained in the first polymerization step.
