    摘要: The present invention relates to a process for the preparation of silicon-dioxide-containing polymer beads by producing a mixture of styrene, crosslinker, finely divided surface-modified silicon dioxide, free-radical initiator and, if appropriate, inert agent and curing the resultant mixture in aqueous phase at elevated temperature to give a polymer bead, the silicon-dioxide-containing polymer beads themselves, and also uses thereof.
