Abstract

A composition results from the mixture of at least one copolymer A resulting from the copolymerization of at least one monomer functionalized 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.
