Filler based on glass particles which contain a homo- or copolymer of vinyl chloride on the surface, process for its preparation and its use as a dental material.

Polymer-coated glass filler for use in dental materials

Polymerizable dental material, characterized in that it contains at least one (meth)acrylamide phosphate of the following general formula (I): in which Ris H or CH; Ris H or a C-Calkyl radical or forms together with the nitrogen atom to which it is bonded and one or more atoms which belong to Ror Ra heterocyclic ring; R, Rindependently of each other are a linear or branched aliphatic C-Cradical with a valency of m+n or p+n, an aromatic C-Cradical with a valency of m+n or p+n, or a cycloaliphatic, araliphatic or heterocyclic C-Cradical with a valency of m+n or p+n, wherein the carbon chains of the radical or radicals can be interrupted by O, S, CONR, OCONH, or form together with one or more atoms which belong to Rand the nitrogen atom, to which the Ris bonded a heterocyclic ring, R' being H if p=0, and Rbeing H, C-Calkyl, C-Caryl, C-aralkyl or a bicylic C-Cradial; n is 1, 2, 3 or 4 if p=0, and is 1 or 2 if p &#x2260;0; m is 1, 2, 3 or 4; p is 0, 1, 2, 3 or 4; x is 0 or S.

Self-etching dental materials based on (METH) acrylamide phosphates

Acrylic ester phosphonic acids of general formula (I), stereoisomers thereof and mixtures of these,wherein n is 1 or 2, on the condition that for n=1 Rhas the meaningand for n=2 Rhas the meaningRis a Cto Calkylene radical, C-Ccycloalkylene radical or Cto Calkylene phenylene radical; Ris hydrogen, a Cto Calkyl radical or a Cto CO-alkyl radical; and R, R, independently of each other, each stand for a Cto Calkyl radical or a Cto CO-alkyl radical.
