Claim Text:
1. A process for preparing homogeneously crosslinked polymers, comprising adding at least one difunctional or polyfunctional 2-oxazoline as a crosslinker to a polymer in the melt, further processing the polymer from the melt comprising coating the melt onto a backing material, and reacting the polymer with the difunctional or polyfunctional 2-oxazoline crosslinker to thermally crosslink the polymer, with at least part of the crosslinking reaction taking place after the further processing at a temperature below the melting temperature of the polymer, wherein 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.
