Abstract

The invention relates to polymerizable preparations that contain: (a) 1 to 80% by weight of an epoxide or of a mixture of epoxides of the general formula (I), wherein n and m independently are 1, 2, 3, or 4, and wherein the molar mass of the epoxide or the average molar mass of the mixture of epoxides is 360 to 3000 g/mole, (b) 0 to 80% by weight of an epoxide or of a mixture of epoxides that are different from (a), (c) 3 to 85% by weight of fillers, (d) 0.01 to 25% by weight of initiators, retarders and/or accelerators, (e) 0 to 25% by weight of adjuvants, the percentages relating to the overall weight of the individual preparation.
