CROSSLINKING OF POLYARYLETHERKETONES

The invention relates to a method for producing a crosslinked moulded article containing polyaryletherketones (PAEK). The method comprises the steps of (a) providing a mixture containing a PAEK and acrosslinking agent; (b) producing a moulded article from the mixture; and (c) thermally treating the moulded article at a temperature at which PAEK is crosslinked to obtain the crosslinked moulded article, wherein the crosslinking agent is a di(aminophenyl) compound in which the two aminophenyl rings are connected to each other via an aliphatic group which has a carbocyclic group. The invention also relates to moulded articles obtainable by using the method, and to the sealing articles. 本发明涉及一种制备含聚芳醚酮(PAEK)的交联模塑制品的方法，所述方法包括以下步骤：(a)提供包含PAEK和交联剂的混合物；(b)由所述混合物制备模塑制品；和(c)在PAEK交联的温度下热处理所述模塑制品，从而获得交联的模塑制品，其中所述交联剂是二(氨基苯基)化合物，其中所述两个氨基苯基环通过具有碳环基团的脂族基团彼此连接。本发明还涉及可通过所述方法获得的模塑制品，并涉及密封制品。
