The invention describes a process for the preparation of hone cements from polyacrylates or polymethacrylates using are X-ray contrast medium, in which the X-ray contrast medium is functionalised with (meth)acrylate groups with prior coating with melamine-formaldehyde resin. The invention furthermore relates to a bone cement and to the use thereof for anchoring prosthesis components in bone, for stiffening bone, as bone screw fixing plug or as implant for anchoring screws.
