Beschreibung
Zusammenfassung:	A polymerisable, radiation curable composition comprising (i) monomers comprising:(a) at least one acrylic acid ester having an additional carboxy group, acrylic acid ester having at least one additional anhydride group of carboxy groups, and/or derivative of the afore-mentioned acrylic acid esters,(b) at least one di-functional acrylate having a bivalent alicyclic group and/or at least one di-functional methacrylate having a bivalent alicyclic group, and(c) optionally, at least one disubstituted 4,4′-di(oxabenzene) dialkyl methane of formula I, and(ii) at least one further component comprising:(d) at least one photoinitiator for the UV and/or Vis spectral region or a photoinitiator system.The composition is suitable for producing dental prosthetic parts, orthopaedic appliances or dental pre-forms, having a) a flexural strength 50 MPa, b) an E-modulus ≥1500 MPa, c) a bending fracture ≥1.1 MPa m1/2, and/or d) a fracture work >250 J/m2 DIN EN ISO 20795-2.
