Abstract
A comb copolymer A2 including at least two boronic ester functions, the copolymer including a main chain and side chains, and at least one portion of the side chains of the copolymer A2 made of oligomers. Also, a composition resulting from mixing at least one polydiol compound A1 and a copolymer A2. The compositions exhibit very varied rheological properties depending on the proportion of the compounds A1 and A2 used. Also, a lubricant composition including such a mixture and at least one lubricating oil. Also, use of this composition to lubricate a mechanical part.
