    Abstract: The invention relates to a method for producing an aqueous dispersion of particles (composite particles) composed of a polymer and a fine-particle inorganic solid. According to said method, at least one ethylenically unsaturated monomer is dispersed in an aqueous medium and is polymerized using at least one radical polymerization initiator in the presence of at least one dispersed, fine-particle inorganic solid and at least one anionic, cationic, non-ionic dispersent, in accordance with the radical aqueous emulsion polymerization method. In said method, a) a stable aqueous dispersion of the inorganic solid(s) is used, said dispersion being characterized in that it has an initial concentration of >/= 1 wt. %, (in relation to the aqueous dispersion of the inorganic solid(s)) and that one hour after production it still retains a dispersion of 90 wt. % of the original dispersed solid, the solid particles of said stable aqueous dispersion having a diameter

    Aqueous dispersion of a polymer and fine particulate inorganic particles, useful as an adhesive, is prepared by a radical aquoeus emulsion polymerization in the presence of the dispersed particles.

    Abstract: An aqueous dispersion (I) of a polymer and fine particulate inorganic particles is prepared by a radical aquoeus emulsion polymerization of an ethylenically unsaturated monomer dispersed in an aqueous medium using a radical initiator in the presence of a dispersed fine particle inorganic solid and a dispersing agent. A process for the preparation of an aqueous dispersion of a polymer and fine particulate inorganic particles comprises radical aquoeus emulsion polymerization of an ethylenically unsaturated monomer dispersed in an aqueous medium using a radical initiator in the presence of a dispersed fine particle inorganic solid and a dispersing agent. The process is characterized by (A) a stable aqueous dispersion containing inorganic material having an initial solids content of at least 1 wt.%, which, one hour after its preparation, retains more than 90 wt.% of the dispersed solids in dispersed form having an average diameter of less than or equal to 100 nm. (B) the dispersion comprising inorganic particles in a standard aqueous alkali chloride solution has a different electrophoretic mobility to the null point at a pH corresponding to the initial pH of the aqueous reaction medium (C) the radical producing component has a electrical charge that is opposite in sign to the electrophoretic mobility of the dispersed particles in a standard aqueous alkali chloride solution at a pH corresponding to the initial pH of the reaction medium. Independent claims are included for (i) an aqueous dispersion (I) of composite particles prepared by the process and (ii) a composite particle powder prepared by drying the dispersion (I).
