Abstract
Polymerizable compositions are described on the basis of (meth)acrylic acid esters which contain as filler a precipitation polymer that is formed from acrylic acid esters and/or methacrylic acid esters, and possibly other copolymerizable monomers, with 10 to 100 mol % of the (meth)acrylic acid esters being bi or polyfunctional. These compositions are particularly suitable as dental compositions.
