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.
