Abstract
Compositions resulting from the mixing of at least: a comb polydiol copolymer A1 and a compound A2 including at least two boronic ester functional groups, the comb polydiol copolymer A1 including a main chain and side chains, at least a portion of the side chains of the copolymer A1 being composed of oligomers. They exhibit very varied rheological properties depending on the proportion of the compounds A1 and A2 used. Composition resulting from the mixing of at least one lubricating oil with such a composition of associative and exchangeable polymers and use of this composition for lubricating a mechanical part.
