  • Crosslinking of polyaryletherketones
    Patent number: 11479629
    Abstract: Provided is a method for the production of a crosslinked molded body containing polyaryletherketone (PAEK), comprising the steps of (a) providing a mixture comprising a PAEK and a crosslinker, (b) preparing a molded body from the mixture, and (c) thermally treating the molded body at a temperature at which PAEK crosslinks, thereby obtaining the crosslinked molded body, and wherein the crosslinker is a di(aminophenyl) compound comprising two aminophenyl rings, wherein the two aminophenyl rings are joined together via an aliphatic group having a carbocyclic rest.
