Abstract

A composition results from the mixture of at least one lubricating oil, at least one statistical copolymer A1 , and at least one compound A2 including at least two boronic ester functions; the statistical copolymer A1 resulting from the copolymerisation of at least a first monomer M1 having diol functions and at least a second monomer M2 having a different chemical structure from that of the M1 monomer. The composition lubricates a mechanical part. The field is that of lubricants.
