Abstract
The invention relates to a monomer mixture for producing a dental material comprising: a. at least one base monomer M1 of the following formula 1: PG-S-A-S—[OOC—K—COO—S-A-S]-PG (formula 1), where PG=a polymerizable group selected from OOC—CH—CHand —OOC—C(CH)—CH; S=a spacer group selected from an unbranched and a branched alkylene, which has C1-C10 carbon atoms and which can also contain oxygen or —OOC— in the carbon chain, or S is omitted; A=an aliphatic polycyclic group; K=an aliphatic acyclic or cyclic saturated or unsaturated unit with C1-C10 carbon atoms; and n=1-9; b. at least one base monomer M2 of the following formula 2: PG'—S′-A′—S′—PG′ (formula 2), where PG′=a polymerizable group selected from OOC—CH═CHand —OOC—C(CH)═CH; S′=a spacer group selected from an unbranched and a branched alkylene, which has C1-C10 carbon atoms and which can also contain oxygen or —OOC— in the carbon chain, or S′ is omitted; and A′=an aliphatic polycyclic group, wherein the mass ratio Y=m(M2)/m(M1) of the base monomers M2 to M1 is 0.9≤Y≤20. The invention also relates to the use of the monomer mixture, to a polymerizable dental material containing such a monomer mixture, to a polymerizable dental material for use in a therapeutic method, and to a cured dental material.
