Abstract

Bone cements containing polyacrylates or polymethacrylates and an X-ray contrast medium can be prepared by functionalizing the X-ray contrast medium with (meth)acrylate groups prior to being coating with melamine-formaldehyde resin and subsequent polymerization. The invention resultant bone cement can be used for anchoring prosthesis components in bone, for stiffening bone, as bone screw fixing plug and as implants for anchoring screws.
