An aliphatic polyketone compound including 85.0 to 99.5 wt % aliphatic polyketone and 0.5 to 15.0 wt % ultra-high molecular weight polyethylene. An aliphatic polyketone compound described where the ultra-high molecular weight polyethylene is 2.0 to 8.0 wt %. An aliphatic polyketone compound where the ultra-high molecular weight polyethylene has a molecular weight greater than 1.0 million g/mol.

Polyketone compound

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.
