Abstract: Crosslinker-accelerator system for the thermal crosslinking of polyacrylates having functional groups capable of entering into linking reactions with epoxide groups, comprising at least one substance having at least one epoxide group as crosslinker and at least one substance of the formula R12N—CR2R3—CR4R5—(CR6R7)n—X in which the R1 independently represent hydrogen, a substituted or unsubstituted alkyl or cycloalkyl radical or together with the nitrogen atom form a 5-7-membered ring; R2, R3, R4, R5, R6 and R7 independently represent hydrogen or an alkyl radical having 1 to 8 carbon atoms or form a 5-7-membered cycloalkylene group; n is an integer from 0 to 4; and X represents —OH, —OR, —SH, —SR and —PR2, in which R independently represents C1-C18 alkyl radical, C2-C18 alkenyl radical or C2-C18 alkynyl radical, an aryl group or an aliphatic or aromatic heterocycle, as accelerator.

Abstract: In the context of a polyacrylate-based composition, the intention is to allow controlled thermal crosslinking. This is accomplished by provision of a crosslinker-accelerator system for the thermal crosslinking of polyacrylates having functional groups suitable for entering into linking reactions with epoxide groups, comprisingat least one substance comprising at least one epoxide group (crosslinker) and at least one substance conforming to the general formula (I) NR3  (I), in which the radicals R independently of one another are a hydrogen atom or an organic radical having 1 to 20 carbon atoms, with at least one of the radicals R being an organic radical with 1 to 20 carbon atoms, and comprising at least one alcoholic OH group.
