Patent ID: 7235602

Claim:
A polymerizable preparation comprising: (a) 1 to 80 weight % of an epoxide or a mixture of epoxides of the general formula: in which A and A′ represent, independently of one another, an unbranched or branched aliphatic, cycloaliphatic or aromatic residue or a combination of these residues with 0 to 16 carbon atoms, in which one or more carbon atoms can be replaced by O, O(C═O), C═O, Si, N or S, X represents an unbranched or branched aliphatic or aromatic residue or a combination of these residues with 3 to 16 carbon atoms, in which one or more carbon atoms can be replaced by O, O(C═O), (C═O), Si, N or S and an aliphatic terminal or centrally located epoxide group is present, L represents an unbranched or branched aliphatic, cycloaliphatic or aromatic residue or a combination of these residues with 6 to 30 carbon atoms, in which one or more carbon atoms can be replaced by O, O(C═O), (C═O), Si, N or S and a cycloaliphatic epoxide group is present, Z and Z′ represent, independently of one another, H or an unbranched or branched aliphatic, cycloaliphatic or aromatic residue or a combination of these residues with 0 to 10 carbon atoms, in which one or more carbon atoms can be replaced by O, O(C═O), (C═O), Si, N or S, D represents one of the following constituents, which is bonded to the constituents A and/or A′ via the silicon atom: i. Si ii. SiG iii. in which G and G′ represent, independently of one another, an unbranched or branched aliphatic, cycloaliphatic or aromatic residue or a combination of these residues with 1 to 8 carbon atoms, in which one or more carbon atoms can be replaced by O, O(C═O), (C═O) or Si, n and m represent, independently of one another, 1, 2, 3 or 4, in which the molar mass of the epoxide or the average molar mass of the mixture of epoxides is 360 to 3,000 g/mol, (b) 0 to 80 weight % of an epoxide or a mixture of epoxides which are different from (a), (c) 3 to 85 weight % of fillers, (d) 0.01 to 25 weight % of initiators, retarders and/or accelerators, (e) 0 to 25 weight % of auxiliaries, in which the percentages are in each case with reference to the total weight of the preparation.
