| titleOfInvention | Pearl-shaped uncured polymers containing a filler, and process for their preparation |
| abstract | (A) 10-60 Gew.-% eines Füllstoffes auf Siliziumdioxidbasis, (B) 40-90 Gew.-% eines (Meth)acrylsäureesters und gegebenenfalls (C) 0-20 Gew:-% an weiteren Monomeren, nmit einem Polymerisationsinitiator aktiviert, in einer wäßrigen Lösung (II) eines hochmolekularen organischen Dispergators dispergiert und die Dispersion durch Erhitzen auf die Zerfallstemperatur des Initiators polymerisiert, dadurch gekennzeichnet, daß der Füllstoff (A) eine mittlere Teilchengröße von 5 bis 100 µm aufweist und mit 1 bis 25 Gew:-% eines Haftvermittlers behandelt ist und daß die Komponenten (B) und (C) im wesentlichen nur eine olefinische Gruppe aufweisende Verbindungen umfassen.Bead polymers with an average particle size of 5 to 150 μm, which are uniformly filled with an inorganic filler, which can be obtained by containing a mixture (1) (A) 10-60% by weight of a filler based on silicon dioxide, (B) 40-90% by weight of a (meth) acrylic acid ester and optionally (C) 0-20% by weight of further monomers, activated with a polymerization initiator, dispersed in an aqueous solution (II) of a high molecular weight organic dispersant and the dispersion polymerized by heating to the decomposition temperature of the initiator, characterized in that the filler (A) has an average particle size of 5 to 100 µm and with 1 to 25% by weight of an adhesion promoter is treated and that components (B) and (C) essentially comprise only compounds containing an olefinic group. |
