<p>Fillers modified superficially with a silane compound (I). Fillers modified superficially with a silane compound (I) of formula ([(PG)-R 1>-Z] n-SP-[Y 1>-R 2>-(AG)] m). A : COOH, -P(=O)(OH) 2, -O-P(=O)(OH) 2, -SO 2OH, -SiR 3>R 4>X or a chelatinized group; R 1>absent or 1-3C -alkylene or cyclopropylene; R 2>absent or 1-8C alkyl; R 3>1-8C alkyl, Cl or OR 5>; R 4>1-8C alkyl, phenyl, Cl or OR 5>; R 5>1-6C alkyl; X : OR 5> or Cl; Y 1>O, S, CO-NH, O-CO-NH, NH-CO-NH or absent; Z : O, S, CO-NR 6>, O-CO-NH, NH-CO-NH or absent; R 6>H or 1-6C alkyl; PG : radically polymerizable group of formula CH(R 11>)(H)=CH(R 9>)-; R 9>H, 1-3C alkyl, 1-3C hydroxyalkyl or COOR 10>; R 10>H, 1-10C alkyl, 1,6-dimethylphenyl or mesityl; R 11>H or phenyl; m : 1 or 2; n : 1-4; and SP : (n+m)-valued linear or branched aliphatic 1-30C group, in which carbon chain is interrupted by O, S, CO-NH, O-CO-NH or NH-CO-NH, (n+m)-valued aromatic 6-18C group, (n+m)-valued cycloaliphatic 3-18C group or (n+m)-valued heterocyclic 3-18C group (all optionally substituted) or absent. When R 2> is absent, then Y 1> is absent; and when AG is silyl group of formula (-SiR 3>R 4>X) and PG is a vinyl group of formula (H 2C=CH-), then simultaneously R 1> and Z are not absent. An independent claim is included for a dental active substance comprising fillers.</p> |
