Cements for orthopaedic or dental surgery are made radio-opaque by using Barium salts or Zirconium oxide particles. We have developed new radio-opaque acrylic cement without such inorganic materials. These cements were obtained by the partial replacement of poly(methyl methacrylate) from the standard cement composition with methacryloyl-oxyethylene phosphate as barium salt, or by the replacement with a copolymer made of methacryloyl-oxyethylene phosphate-barium salt with methyl methacrylate. The final cements were characterised by X-ray radio-opacity and mechanical resistance. The use of methacryloyl-oxyethylene phosphate-barium salt is the optimum solution for obtaining radio-opaque cements with improved mechanical properties
