摘要： The present invention relates to a cationically polymerizable composition comprising or consisting of: (a1) 35 to 90 wt % of at least one (meth)acrylic ester of the general formula (I) in which R1 is selected from H and CH3 and R2 is a linear or branched alkyl chain having 1 to 30 carbons; (a2) 5 to 30 wt % of at least one olefinically unsaturated monomer having at least one cationically polymerizable functional group; (a3) 5 to 30 wt % of at least one alkoxysilane-modified (meth)acrylic ester; (a4) optionally 5 to 30 wt % of at least one N-vinyl-substituted lactam; and (a5) optionally up to 5 wt % of at least one (meth)acrylic ester different from (a1) and/or of at least one olefinically unsaturated monomer which is copolymerizable with components (a1) to (a4). The invention further relates to a pressure sensitive adhesive and also to a structural pressure sensitive adhesive, which are obtainable by polymerization and optional subsequent additional crosslinking of such a composition, and also to the use of these pressure sensitive adhesives.

摘要： 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.

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.
