Abstract: 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.

Abstract: The intention is to provide a thermally crosslinkable, polyacrylate-based composition which can be processed from the melt and is distinguished by long pot life and by rapid and complete or near-complete crosslinkability even at relatively low temperatures, which can be processed to a pressure-sensitive adhesive. This aim is accomplished with a composition which comprises a) at least one crosslinkable poly(meth)acrylate; b) at least one organosilane conforming to the formula (1) R1—Si(OR2)nR3m  (1), in which R1 is a radical containing a cyclic ether function, the radicals R2 independently of one another are each an alkyl or acyl radical, R3 is a hydroxyl group or an alkyl radical, n is 2 or 3 and m is the number resulting from 3-n; and c) at least one substance accelerating the reaction of the crosslinkable poly(meth)acrylate with the cyclic ether functions. The patent application further provides a pressure-sensitive adhesive obtainable from the composition.
