Abstract: Disclosed is a composition including a network of cross-linked polymers. The network is prepared by one of the following radical copolymerisations. First, there is copolymerization of monomers, polymer of interest precursors, the monomers carrying at least one functional group that is polymerisable by radical polymerization. Second, there is copolymerization of 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 polymerization. Third, there is a copolymerization of a 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.

Abstract: The object of the invention is polymer compositions comprising cross-linked polymer comprising boronic ester functions enabling exchange reactions, as well as free monofunctional boronic esters. The compositions are obtained from the modification of a polymer by a functionalized boronic ester additive. This polymer can be pre-functionalized boronic ester or functionalized on addition of the said additive. In particular, the invention relates to a process enabling the behavior of a polymer to be modified by addition of a functional additive, enabling a cross-linked network containing exchangeable boronic ester links to be formed.

Abstract: The object of the invention is a polymer composition including cross-linked polymers, which contain boronic ester functions enabling exchange reactions, as well as free monofunctional boronic esters. This composition originates from the polymerization of precursor monomers to thermoplastic polymers including at least one pending boronic ester group, the pending boronic ester group not containing any polymerizable groups, and cross-linking agent comprising at least one boronic ester group. This enables the formation of a network of cross-linked polymers containing pending functions and cross-links that are exchangeable by boronic ester metathesis reactions. Another object of the invention is processes for preparing this composition and materials and formulations comprising this composition.
