| abstract |
Compositions resulting from the mixing of at least one oligomer A1, resulting from the copolymerisation of at least one monomer functionalised by diol functions with at least a second monomer, and at least one compound A2 comprising at least two boronic ester functions. The claimed compositions exhibit very varied rheological properties, depending on the proportion of the compounds A1 and A2 used. The invention also relates to a composition resulting from mixing at least one lubricating oil with such a composition of associative and exchangeable polymers, and to the use of this composition to lubricate a mechanical part. |
