摘要： A method of producing an improved polyethylene, especially an ultra-high molecular weight polyethylene utilizes a sequential irradiation and annealing process to form a highly cross-linked polyethylene material. The use of sequential irradiation followed by sequential annealing after each irradiation allows each dose of irradiation in the series of doses to be relatively low while achieving a total dose which is sufficiently high to cross-link the material. The process may either be applied to a preformed material such as a rod or bar or sheet made from polyethylene resin or may be applied to a finished polyethylene part. If applied to a finished polyethylene part, the irradiation and annealing must be accomplished with the polyethylene material not in contact with oxygen at a concentration greater than 1% oxygen volume by volume. When applied to a preform, such as a rod, the annealing of the bulk polymer part of the rod from which the finished part is made must take place on the rod before the implant is machined therefrom and exposed to oxygen.

摘要： A method for manufacturing of ultrahigh molecular weight polyethylene (UHMWPE) for implants, where the implants have been machined out of UHMWPE blocks or extruded rods, has anthocyanin dispersely imbedded in the polyethylene. The implant is then exposed to γ ray or electron beam irradiation in an amount of at least 2.5 Mrad followed by a heat treatment to prevent the implant from becoming brittle in the long term as well as to improve strength and wear. The method includes mixing a powder or granulate resin of UHMWPE with an aqueous liquid that contains anthocyanin in a predetermined amount. The water is then evaporated in order to deposit the anthocyanin in a predetermined concentration on the polyethylene particles. The doped UHMWPE particles are compressed into blocks at temperatures in a range of approximately 135° C.-250° C. and pressures in a range of approximately 2-70 MPa. Medical implants are made from the blocks.
