| abstract |
The object of this invention is a bone cement comprising a mixture of polyacrylate and/or polymethacrylate pre-polymers, monomeric acrylic and/or methacrylic acid derivatives, a polymerization catalyst and possibly a stabilizing agent and an accelerator, and a process for the preparation and application thereof. In the bone cement of the invention, the pre-polymer is a mixture of 5-50% by weight of polyacrylate and/or polymethacrylate fibers with a length of greater than 2 mm and up to 15 mm and a thickness of 50-750 μm, and 50-95% by weight of polyacrylate and/or polymethacrylate pearl polymers consisting of 1-140 μm polymer beads, preferably between 30 and 40 μm as uniform in size as possible, the surface of which is advantageously enlarged by mechanical and/or chemical treatment. The prepolymer may also consist entirely of bead-shaped particles. |
