Abstract

Crosslinker/accelerator system for thermally crosslinking polyacrylates with functional groups that are adapted to react with epoxy groups in a crosslinking reaction, comprising at least one epoxy group-containing substance and at least one substance that accelerates the crosslinking reaction at a temperature below the melting temperature of the polyacrylate.
