Polymergranulat und Verfahren zu seiner Herstellung

摘要

The invention concerns a material suitable for use as a bone substitute or as a material for anchoring endoprosthesis components in place, plus a method of producing the material. The material described contains a polymer and/or copolymer plus filler particles which are at least partly enclosed in the polymer and/or copolymer. The material is granulate or fibrous in nature and is produced by mixing the polymer powder and filler particles to give a homogeneous mixture which is then heated and extruded through a nozzle, or the polymer powder is heated and the filler injected hot upstream of or directly into the extrusion nozzle. Following hardening, the mixture is ground to give a granulate material or the polymer fibres obtained are cut to the required length.
