COMPOSITION OF RETICULATED POLYMERS CONTAINING EXCHANGEABLE PENDING LINKS AND EXCHANGEABLE CROSSLINKING POINTS, BY ALDEHYDE-IMINE EXCHANGE REACTIONS AND / OR IMINE-IMINE EXCHANGE REACTIONS, PROCESSES OF PREPARATION AND USE

摘要

The subject of the invention is a composition comprising (a) crosslinked polymers containing exchangeable pendant bonds and exchangeable crosslinking points, by aldehyde-imine exchange reactions and / or by imine-imine exchange reactions, obtained by crosslinking linear or branched polymers and (b) monofunctional free aldehydes and / or monofunctional free imines. The invention also relates to processes for preparing such a composition and the uses of the composition. The invention also relates to combinations for cross-linking linear or branched polymers, and their use for forming a composition comprising crosslinked polymers containing exchangeable pendant bonds and crosslinking points exchangeable by aldehyde-imine exchange reactions and / or by imine-imine exchange reactions. The invention finally relates to the use of aldehyde to catalyze imine-imine metathesis reactions and imine-aldehyde exchange reactions.
