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.
