Dental material based on ring-openable, polymerisable, acidic monomers

摘要

Dental material (A) comprises at least a radically polymerizable monomer (I). Dental material (A) comprises at least a radically polymerizable monomer (I) of formula ((PG-X 1>-R 1>-X 2>) n-R-(Y 1>-R 2>-HG) m). PG : cyclic, ring opening polymerizable group of formula (a), (b) or (c); Z : O, S, -C(R 8>)(R 7>)- or -C(R 9>)(R 1> 0>)-C(R 1> 1>)(R 1> 2>)-; R 4>, R 5>H or 1-10C alkyl; R 6>H, 1-10C alkyl, phenyl- or benzyl residue; R 7>, R 8>H, CN, CO-OR 1> 3>, -CO-R 1> 3> or R 1> 3>; R 9>-R 1> 2>H, -CO-OR 1> 3>, -CONHR 1> 3>, -CO-R 1> 3>, 1-15C alkyl that is interrupted by O, 4-12C cycloaliphatic residue, 5-12C bicyclic residue, 6-14C aryl or 7-20C alkylaryl; R 1> 3>1-15C alkyl that is interrupted by O, 4-12C cycloaliphatic, 5-12C bicyclic, 6-14C aryl or 7-20C alkylaryl residue, where the residues are same or different; X 1>, X 2>, Y 1>absent, O, S, ester-, amide- or urethane group; R : (n+m)-valent 1-35C organic residue with 0-8 heteroatom, where the hydrogen atom is substituted entirely or partially by F atoms; R 1>, R 2>, R 3>absent, 1-16C alkylene that is interrupted by O atoms; HG : -P=O(OH) 2, -P=O(OH)(OR 1> 4>), -O-P=O(OH) 2, -O-P=O(OH)(OR 1> 5>) or -SO 2OH; R 1> 4>, R 1> 5>1-15C alkyl, phenyl- or benzyl-residue; q, p : 0-3; r : 0 or1; n : 1-6; and m : 1-3. An independent claim is included for the manufacture of a mold forming (A) to a body with a desired form and subsequently entirely or partially hardened. [Image].
