Abstract
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.
Claims12
A crosslinkable adhesive comprising
- at least one polymer functionalised with organic and/or inorganic acid units containing OH groups, and at least one cyclic phosphonic anhydride.
A method for crosslinking crosslinkable adhesives comprising crosslinking an adhesive comprising at least one polymers functionalised with organic and/or inorganic acid units containing OH groups, wherein at least one cyclic phosphonic anhydride is used as crosslinking activator.
