The invention relates to a crosslinker/accelerator system for thermally crosslinking polyacrylates with functional groups that are adapted to react with epoxy groups in a crosslinking reaction. Said system comprises at least one epoxy group-containing substance (crosslinker) and at least one substance (accelerator) that accelerates the crosslinking reaction at a temperature below the melting temperature of the polyacrylate. L'invention concerne un système d'agent accélérateur/agent réticulant destiné à la réticulation thermique de polyacrylates comportant des groupes fonctionnels, adaptés à des réactions de combinaison avec des groupes époxydes. Le système d'agent accélérateur/agent réticulant contient au moins une substance contenant des groupes époxydes (agent réticulant) et au moins une substance (agent accélérateur) ayant un effet accélérateur sur la réaction de combinaison à une température inférieure à la température de fusion.
