    Abstract: Controlled thermal crosslinking in a polyacrylate-based composition is accomplished by a crosslinker-accelerator system for the thermal crosslinking of polyacrylates having functional groups suitable for entering into linking reactions with epoxide groups, comprising at leastone substance comprising at least one epoxide group (crosslinker) and at least one substance of the general formula (I) R1R2N—CR3R4—CR5R6—(CR7R8)n—NR9R10  (I) wherein the radicals R1, R2, R9 and R10 independently of one another are a hydrogen atom or a substituted or unsubstituted alkyl or cycloalkyl radical having 1 to 8 carbon atoms or an alkylene group bonded to the main chain and having 1 to 8 carbon atoms, where at least one of the radicals R1, R2, R9 and R10 is not a hydrogen atom; the radicals R3, R4, R5, R6, R7 and R8 independently of one another are a hydrogen atom or an alkyl group having 1 to 8 carbon atoms or form a 5-7-membered cycloalkylene group; and n is an integer from 0 to 4 (accelerator).

    Abstract: The invention relates to a process for preparing pressure-sensitive adhesives (PSAs) which have high molar masses in combination with a narrow molar mass distribution, and also to PSAs, especially polyacrylate-based PSAs, prepared accordingly.It has been found that, surprisingly, polymers with high molar masses and a narrow molar mass distribution, more particularly polyacrylates with high molar masses and a narrow molar mass distribution, can be prepared outstandingly in particular by means of RAFT processes in the presence of a diradical initiator which undergoes thermal cyclization to form a diradical, these polymers being suitable for use as high-shear-strength PSAs.
