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.
Claims13
A polyacrylate melt comprising a crosslinker-accelerator system for the thermal crosslinking of polyacrylates with functional groups capable of entering into linking reactions with epoxide groups, comprising at least one substance containing epoxide groups, in an amount of 0.1 to 5% by weight of the polyacrylate, and at least one substance which has an accelerating effect for the linking reaction at about room temperature.
Process for thermal crosslinking in the melt of polyacrylates with functional groups capable of entering into linking reactions with epoxide groups, wherein said thermal crosslinking is carried out in the melt in the presence of a crosslinker-accelerator system comprising substances containing epoxide groups, in an amount of 0.1 to 5% by weight of polyacrylate, and at least one substance which has an accelerator action for the linking reaction at about room temperature.
