Monomer mixtures for producing dental materials

The invention relates to a monomer mixture for preparing 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] n-PG (formula 1) wherein PG = polymerizable groups selected from the group consisting of OOC-CH = CH2 and-OOC-C (CH3) = CH2; s = a spacer group selected from branched and unbranched alkylene groups having a C1-C10 carbon atom, which can additionally contain oxygen or-OOC-in the carbon chain, or S is absent; a is an aliphatic polycyclic group; k = an aliphatic, acyclic or cyclic saturated or unsaturated unit having a C1-C10 hydrocarbon atom; n is equal to 1-9; b. At least one base monomer M2 of the following formula 2: PG '-S'-A '-S'-PG '(formula 2), wherein PG' = a polymerizable group selected from the group consisting of OOC-CH = CH2 and-OOC-C (CH3) = CH2; s '= a spacer group selected from the group consisting of unbranched and branched alkylene groups having C1-C10 carbon atoms, which can additionally contain oxygen or-OOC-in the carbo
