COMPOSITION COMPRISING A CROSS-LINKED POLYMER NETWORK, PREPARED BY RADICAL COPOLYMERISATION, COMPRISING PENDING LINKS AND CROSS-LINKS EXCHANGEABLE BY ALDEHYDE-IMINE EXCHANGE REACTIONS AND/OR BY IMINE-IMINE EXCHANGE REACTIONS, PREPARATION PROCESS AND USE
The object of the invention is a composition comprising a network of cross-linked polymers. Said network is prepared by radical copolymerisation of the following compounds:(a) Monomers, polymer of interest precursors, said monomers carrying at least one functional group that is polymerisable by radical polymerisation;(b) Monomers comprising at least one pending imine group and carrying at least one functional group that is polymerisable by radical polymerisation; and/or monomers comprising at least one pending aldehyde group and carrying at least one functional group that is polymerisable by radical polymerisation;(c) Cross-linking agent comprising aldehyde and/or imine groups enabling the formation of a cross-linked polymer network containing pending functions and cross-links that are exchangeable by aldehyde-imine exchange reactions and/or by imine-imine exchange reactions;;Another object of the invention is a material obtained from the composition according to the invention and a preparation process. Another object of the invention is a formulation comprising a composition according to the invention.;Finally, an object of the invention is the use of aldehyde to catalyse imine-imine metathesis reactions and imine-aldehyde exchange reactions.
