摘要： The invention relates to a UV-cross-linked, polyacrylate-based adhesive mass that has high adhesive force and high cohesion and that can be produced by means of a hot-melt process with subsequent cross-linking. This is achieved by providing an adhesive mass that can be obtained by cross-linking a composition, which comprises at least one poly(meth)acrylate having a weight-average molar mass Mw of at least 100,000 g/mol and at least one polyfunctional α-cleaver and is characterized in that the composition contains at least one adhesive-force-increasing resin having a weight average molar mass Mw of at most 30,000 g/mol, which resin can be obtained by polymerizing a monomer composition M1, comprising at least one compound according to formula (I) H2C═C(R1)(COOR2), wherein R1 represents a hydrogen atom or a methyl group and R2 represents a hydrogen atom or a functionalized or non-functionalized C1-C20 alkyl group.

摘要： 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, comprising at 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.
