Abstract (en)
[origin: WO2022253551A1] The invention relates to a monomer mixture for producing a dental material comprising: a. at 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), where PG = a polymerizable group selected from OOC- CH=CH2 and -OOC-C(CH3)=CH2; 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=CH2 and -OOC-C(CH3)=CH2; 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.
