| 摘要 |
<p>Bone cement mixture comprises a polymer component containing a X-ray contrast agent and a monomer component, where the X-ray contrast agent is present as essentially spherical polymer or copolymer particles with dispersed X-ray opaque inorganic nano-particles with a particle size of 3-15 nm, manufactured by suspension polymerization in the presence of nano-particles, where the nano-particles are covered completely by the copolymer material, and the inorganic nano-particles consist essentially of zirconium oxide. Independent claims are included for: (1) the X-ray contrast agent; and (2) a method for the production of the X-ray contrast agent, comprising polymerizing zirconyl-dimethacrylate and/or other zirconium and/or methacrylate containing other X-ray opaque elements to form a polymer or a copolymer.</p> |
