摘要：
A medical implant comprising an olefinic material having a molecular weight greater than 400,000. The material is irradiated to create free radicals while out of contact with oxygen in a concentration greater the 1% volume by volume and then heated while out of contact with oxygen in a concentration greater than 1% volume by volume at a temperature of greater than 25°C for a sufficient time to create a level of cross-links between free radicals at least equivalent to the level created by heating the olefinic material to 50°C for 144 hours.
