The invention relates to polymerizable compositions comprising (a) 3 to 80 wt. % of an epoxide or a mixture of epoxides of the general formula: in which, for type A: if n=2 Z denotes a cycloaliphatic or aromatic radical having 1 to 22, preferably 1 to 18 C atoms or a combination of these radicals, wherein one or more C atoms can be replaced by O, C=O, -O(C=O)-, SiR2 and/or NR, or an aliphatic radical having 0 to 22, preferably 1 to 18 C atoms, wherein one or more C atoms can be replaced by O, C=O, -O(C=O)-, NR or SiR2, wherein at least one C atom must be replaced by SiR2, and wherein R is an aliphatic radical having 1 to 7 C atoms, wherein one or more C atoms can be replaced by O, C=O and/or -O(C=O)-, if n>2 Z denotes an aliphatic, cycloaliphatic or aromatic radical having 0 to 22, preferably 0 to 18 C atoms or a combination of these radicals, wherein one or more C atoms can be replaced by O, C=O, -O(C=O)-, SiR2 and/or NR and wherein R is an aliphatic radical having 1 to 7 C atoms, wherein one or more C atoms can be replaced by O, C=O and/or -O(C=O)-, and in which, for type B: Z denotes an aliphatic, cycloaliphatic or aromatic radical having 0 to 22, preferably 0 to 18 C atoms or a combination of these radicals, wherein one or more C atoms can be replaced by O, C=O, -O(C=O)-, SiR2 and/or NR and wherein R is an aliphatic radical having 1 to 7 C atoms, wherein one or more C atoms can be replaced by O, C=O and/or -O(C=O)-, and in which, for type A and type B: A denotes an aliphatic, cycloaliphatic or aromatic radical having 1 to 18 C atoms or a combination of these radicals, wherein one or more C atoms can be replaced by O, C=O, -O(C=O)-, SiR2 and/or NR, wherein R is an aliphatic radical having 1 to 7 C atoms, in which one or more C atoms can be replaced by O, C=O and/or -O(C=O)-, B1, B2, D and E independently of one another denote an H atom or an aliphatic radical having 1 to 9 C atoms, wherein one or more C atoms can be replaced by O, C=O, -O(C=O)-, SiR2 and/or NR, wherein R is an aliphatic radical having 1 to 7 C atoms, in which one or more C atoms can be replaced by O, C=O and/or -O(C=O)-, n denotes 2-7, m denotes 1-10, p denotes 1-5, q denotes 1-5 and x denotes CH2, S or O, (b) 0 to 80 wt. % of an epoxide or a mixture of epoxides which differ from (a), (c) 3 to 85 wt. % of fillers, (d) 0.01 to 25 wt. % of initiators, retardants and/or accelerators, (e) 0 to 25 wt. % of auxiliaries, the percentage data in each case being based on the total weight of the composition. The new polymerizable compositions are particularly suitable as dental compositions.
