Patent ID: 6852795

Claim:
Monomers according to the following formula: in which the following mean: n=an integer from 0 to 10; A=H or linear or branched C 1 to C 15 alk(en) yl, or C 3 to C 15 cycloalk(en)yl or C 6 to C 12 aryl or C 8 -C 18 alkaryl, of the named radicals, one or more C atoms in each case being able to be replaced by O, C═O, O(C═O), and/or NR, R being an aliphatic radical with 1 to 7 C atoms, in which one or more C atoms can be replaced by O, C═O and/or O(C═O); D=E or a hydrocarbon structure which links 2 to 10 cyclosiloxane radicals, the structure being linear or branched or cyclic or polycyclic and containing 2 to 50 C atoms and additionally 0 to 30 other atoms from the group O, N, S, F, Cl, F, Br, I and to which 1 to 9 of the above-defined cyclosiloxane radicals according to formula (1), excluding D, are attached; E=A or a polymerizable group taken from the group G-C[(Q-T-L) a (A) 3-a ] and/or Q-L and optionally also X-T-L, up to 50% of groups E being permitted to correspond to A in an average molecule, with the proviso that in the case of molecules with only one siloxane ring, under 25% to 0% of the groups E are permitted to correspond to A in an average molecule, and with the proviso that at least one group G-C[(Q-T-L) a (A) 3-a ] and/or Q-L must be contained in the molecule; G=linear, branched or cyclic C 1 to C 25 alk(en)ylene, arylene, alkarylene, arylalkylene, 0 to 5 C atoms being able to be replaced by a representative of the group O, S, N-A, C(O), C(O)O, OC(O), C(O)N, NC(O), OC(O)O, NC(O)O, OC(O)N, NC(O)N; X=C 1 to C 10 alk(en)ylene; Q=a radical containing an aromatic or polycyclic ring system in the chain, with 5 to 20 C atoms, which independently of each other also has 0 to 5 heteroatoms from the group O, N-A, S in the ring system, with the exception of tricyclo[5.2.1.0 2.6 ]decanyl-groups; T=O, N-A or a bi- or multivalent linear, branched or cyclic alcohol, amine or amino alcohol radical with 2 to 10 C atoms; L=an acrylate or methacrylate group; a=2, 3.
