摘要：
Shaped parts of ultra high molecular weight polyethylene (UHMWPE) are made by a process comprising melt processing, wherein a) the UHMWPE has a weight average molecular weight (Mw) of at least 1*106 g/mol, b) during the shaping the storage plateau modulus of the UHMWPE (G*) is kept at a value of at most 1.5 MPa, c) whereafter, before the cooling, the G* is raised to its final value. The shaped parts may advantageously be used in medical applications, e.g., as an element of a hip or knee prosthesis.
摘要（中）：
通过包括熔融加工的方法制备超高分子量聚乙烯（UHMWPE）的成型部件，其中a）UHMWPE的重均分子量（Mw）至少为1 * 106g / mol，b）在成形期间 UHMWPE的储存平稳模量（G *）保持在至多1.5MPa的值，c）然后在冷却之前将G *升高到其最终值。 成形部件可有利地用于医疗应用中，例如用作髋部或膝关节假体的元件。
