POLYMER COMPOSITIONS COMPRISING CROSS-LINKED POLYMERS COMPRISING BORONIC ESTER FUNCTIONS ENABLING EXCHANGE REACTIONS, PROCESS FOR PREPARING THEM AND THEIR USE

摘要

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.
