    摘要: The invention relates to a process for preparing homogeneously crosslinked polymers, in which at least one crosslinker is added to a polymer in the melt, in which the polymer is further processed from the melt, and in which a thermal crosslinking reaction is brought about by means of the crosslinker, with at least part of the crosslinking reaction taking place after the further processing at a temperature below the melting temperature of the polymer, characterized in that the crosslinker comprises an at least difunctional compound, at least one of the functional groups being an oxazoline group, and the polymer contains functional groups which, at a temperature below the melting temperature of the polymer, are able to react with the oxazolines in a linking reaction in the sense of the thermal crosslinking reaction.
