The object of the invention is a 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 functionalised boronic ester additive. This polymer can be pre-functionalised boronic ester or functionalised on addition of the said additive. In particular, the invention relates to a process enabling the behaviour 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.

The object of the invention is a polymer compositions comprising cross-linked polymer comprising boronic ester functions enabling exchange reactions, as well as free monofunctional boronic esters.

These compositions arise from the polymerisation of precursor monomers to thermoplastic polymers comprising at least one pending boronic ester group, said pending boronic ester group not containing any polymerisable group and cross-linking agent comprising at least one boronic ester group enabling the formation of a network of cross-linked polymer containing pending functions and cross-links that are exchangeable by boronic ester metathesis reactions.

Another object of the invention are processes for preparing this composition and materials and formulations comprising this composition.

A composition results from the mixture of at least one copolymer A resulting from the copolymerisation of at least one monomer functionalised by diol functions and at least one compound A2 comprising at last two boronic ester functions. They have rheological properties which are very varied according to the proportion of the A1 and A2 compounds used. The field is that of associative and exchangeable polymers.
