Composition, preparation method, and use of crosslinked polymer containing pendant binding and exchangeable cross-linking by aldehyde imine and / or imine imine exchange reaction

摘要

The object of the present invention is: (a) a crosslinked polymer obtained by crosslinking of a linear or branched polymer, containing pendant bonds and crosslinking exchangeable by aldehyde-imine exchange reaction and / or imine-imine exchange reaction, And (b) a composition comprising a free monofunctional aldehyde and / or a free monofunctional imine. Another object of the present invention is a process for the preparation of such compositions and the use of the compositions. Another object of the invention comprises a composition for cross-linking linear or branched polymers, and pendant linkages and cross-links exchangeable by aldehyde-imine exchange reaction and / or imine-imine exchange reaction. Its use to form a composition comprising a crosslinked polymer. Finally, the object of the present invention is the use of aldehydes to catalyze imine-imine metathesis reactions and imine-aldehyde exchange reactions.
