| abstract | PROBLEM TO BE SOLVED: To provide a method for increasing the wear resistance of a biologically implantable polymer part. SOLUTION: The bulk raw material, unfinished or finished part is placed in a substantially oxygen-free gas-impermeable package, and the package and contents are of sufficient degree to form the desired high level of crosslinking within the polymer. Irradiating with a penetrating radiation until the object, while obtaining high elongation at break, effective period to stabilize the raw material against the oxidation reaction that occurs by reacting the reactant species and the released gas, Heating to a thermal threshold below the melting point of the polymer improves the wear and oxidation resistance of the biologically implantable polymer prosthetic component. This stabilization method is preferably carried out in the packaged part in the presence of the gas released upon irradiation, substantially eliminating free radicals without introducing further thermal crosslinking. This method can be applied to finished parts because the dimensions of the parts do not change. In this way, very high levels of crosslinking can be achieved while maintaining mechanical strength to reduce the tendency for aging or chemical degradation. |
