Abstract:
The invention relates to a polymerizable dental material containing a catalyst paste (A) and a base paste (B), wherein the catalyst paste (A) contains at least one organic peroxygen compound, at least one radically polymerizable organic (meth)acrylic monomer and at least one filler, and wherein the base paste (B) contains at least one radically polymerizable organic (meth)acrylic monomer, an amine as co-initiator of the radical polymerization, at least one filler and at least one salt-like, water-soluble, powdery reduction agent dispersed therein, wherein the catalyst paste (A) and/or the base paste (B) contains at least one phase transfer catalyst that is selected from the group consisting of the ammonium, phosphonium and/or sulfonium salts that contain an inorganic or organic anion, provided that the phase transfer catalyst—in the event of organic anions—contains only those having 1-4 carbon atoms, and that anions of sulfinic acids are precluded.
