DENTAL MATERIAL CONTAINING PHOSPHONIC ACIDS

DENTAL MATERIAL CONTAINING PHOSPHONIC ACIDS

A dental material contains a hydrolysis-stable phosphonic acid or salt with ethylenically-unsaturated double bond(s). A dental material contains one or more phosphonic acids or salts of formula (I): R = alkyl or alkylene of ≥ 6C or aryl (sic), or -CO-NR1R8 or Cn'H2n'-COONH-Cn'H2n'...

Zusammenfassung:A dental material contains a hydrolysis-stable phosphonic acid or salt with ethylenically-unsaturated double bond(s). A dental material contains one or more phosphonic acids or salts of formula (I): R = alkyl or alkylene of ≥ 6C or aryl (sic), or -CO-NR1R8 or Cn'H2n'-COONH-Cn'H2n', ether or a further urethane group, or -R10-X(R11)2; R1 = H, alkyl or aryl; R8 = aryl, CnH2n (n = 4-18), CnH2n-Si(R5)2-(O-Si(R5)2)m-CnH2n n = 3-12; n' = 4-12; m = 1-10; R5 = Me, Et or phenyl; R7 = Me, Et, Pr, iso-Pr or Bu, COOR9, CONHR9, H or phenyl; R10 = aryl, alkyl with ≥ 3C or polyether with 1-10 polyether units; R9 = Me, Et, Pr, iso-Pr or Bu; R11 = alkyl or aryl; X = N, B or CH; p = 1 or 2;
