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 The pressure-sensitive adhesive can be used for bonding parts in mobile electronic devices.

Pressure-sensitive adhesive based on acrylonitrile butadiene rubbers

The present invention relates to a cationically polymerizable composition comprising or consisting of:  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.

Cationically polymerisable polyacrylate containing alkoxysilane groups and use thereof

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 formulaRN&#x2014;CRR&#x2014;CRR&#x2014;(CRR)&#x2014;Xin which the Rindependently represent hydrogen, a substituted or unsubstituted alkyl or cycloalkyl radical or together with the nitrogen atom form a 5-7-membered ring;R, R, R, R, Rand Rindependently represent hydrogen or an alkyl radical having 1 to 8 carbon atoms or form a 5-7-membered cycloalkylene group;n=0; andX represents &#x2014;OH, &#x2014;OR, &#x2014;SH, &#x2014;SR and &#x2014;PR, in which R independently represents C-Calkyl radical, C-Calkenyl radical or C-Calkynyl radical, an aryl group or an aliphatic or aromatic heterocycle, as accelerator.

Crosslinker-accelerator system for polyacrylates

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

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 least

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 formulaRN&#x2014;CRR&#x2014;CRR&#x2014;(CRR)&#x2014;Xin which the Rindependently represent hydrogen, a substituted or unsubstituted alkyl or cycloalkyl radical or together with the nitrogen atom form a 5-7-membered ring;

The present invention relates to a method for thermal crosslinking of adhesives and also to products produced with these adhesives. An object of the invention is to provide a method for thermal crosslinking of adhesives where the crosslinking is covalent and (initiated by a chemical or physical stimulus) reversible. As and when required, the crosslinking method can also be configured to result in a covalent, irreversible network.
