Abstract

The present invention is directed to polymerizable dental compositions containing (a) 3 to 80 wt. % of cycloaliphatic epoxides; b) 0 to 80 wt. % of an epoxide or a mixture of epoxides which are different from a); c) 3 to 85 wt. % of a filler material; d) 0.01 to 25 wt. % of initiators, inhibitors and/or accelerators; e) 0 to 25 wt. % of auxiliary agents, the individual percentages of which are in relation to the total weight. The new polymerizable agents are particularly suited as dental material.
