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: 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.

Abstract: Pressure-sensitive adhesives based on acrylonitrile-butadiene rubbers having good shock-resistance combined with easy removability of the adhesives from the substrate shall be provided. This is solved by a pressure-sensitive adhesive which comprises at least one acrylonitrile-butadiene rubber; and at least one tackifier resin, and is characterized in that the acrylonitrile content of the acrylonitrile rubber is less than 30 wt %; the pressure-sensitive adhesive comprises at least one rosin resin as tackifier resin; and the entirety of all tackifier resins has an acid number of 6-150. The pressure-sensitive adhesive can be used for bonding parts in mobile electronic devices.
