摘要：
Dental material which contains at least one radically polymerizable monomer according to the general formula (I): in which PG is a cyclic, ring-opening polymerizable group; X1 is absent, O, S, is an ester, amide or urethane group; X2 is absent with, O, S, is an ester, amide or urethane group; Y is absent, O, S, is an ester, amide or urethane group; R is an organic radical with a valency of (n+m), with 1 to 35 carbon atoms and 0 to 8 heteroatoms, the H atoms of which can be wholly or partially substituted by F atoms; R1 is absent or is a C1-C16 alkylene radical which can be interrupted by O atoms; R2 is absent or is a C1-C16 alkylene radical which can be interrupted by O atoms; n is 1, 2, 3, 4, 5 or 6; m is 1, 2 or 3; HG is —P═O(OH)2; —P═O(OH)(OR14); —O—P═O(OH)2, —O—P═O(OH)(OR15) or —SO2OH, wherein R14 is a C1-C15 alkyl radical, phenyl or benzyl radical; and R15 is a C1-C15 alkyl radical, phenyl or benzyl radical.
