Abstract

High-temperature resistant polymerizable metal oxide particles having a glass transition temperature of the homopolymerizable ≧100° C. and a core A. The core includes an oxide of a metal or semimetal of the third to sixth main group, of the first to eighth subgroup of the periodic table, or of the lanthanides, and has at least one group —(B)w—X bound via the oxygen atom of the oxide or hydroxide, in which B represents a binding link, and X represents a reactive functional group, and w is equal to 0 or 1. The inventive particles are useful, in particular, for producing coating materials, molding materials and adhesives.
