The invention relates to a dental composition comprising a monomer or mixture of monomers represented by the following structure (1) with 1,2R independently selected from H, alkyl (e.g. CH3C2H5), and Phenyl, 3,4R independently selected from H, alkyl (e.g. CH3), and halogen (Cl, Br, F), 5R independe

The invention relates to a dental composition comprising a monomer or mixture of monomers represented by the following structure (1) with 1,2R independently selected from H, alkyl (e.g. CH3C2H5), and Phenyl, 3,4R independently selected from H, alkyl (e.g. CH3), and halogen (Cl, Br, F), 5R independently selected from H, alkyl (e.g. CH3), m, n=1, 2 and x+y=2 to 10, with the proviso that if m=n=2, than x+y=2 and if m=n=1, than x+y=4 to 10. The invention also relates to a process for producing the monomer or mixture of monomers and the use thereof especially as dental composition.
