Abstract: Compositions are obtained by mixing at least one oligomer A1, which is obtained by copolymerizing at least two monomers functionalized by diol functions with at least one second monomer, with at least one compound A2 having at least two boron ester functions. The compositions exhibit very varied rheological properties depending on the proportion of the compounds A1 and A2 used. A composition is also obtained by mixing at least one lubricating oil with such a composition of associative and exchangeable polymers, and the use of this composition to lubricate a mechanical part.

Abstract: Compositions resulting from the mixing of at least one oligomer A1, resulting from the copolymerization of at least one monomer functionalized by diol functions with at least a second monomer, and at least one compound A2 including at least two boronic ester functions. The compositions exhibit very varied rheological properties, depending on the proportion of the compounds A1 and A2 used. A composition also results 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.

Abstract: The invention concerns additive compositions obtained by mixing at least two thermoassociative and exchangeable compounds and at least one boronic ester compound that enables the association of these two copolymers to be controlled; a lubricating composition obtained by mixing at least one lubricating base oil, at least two thermoassociative and exchangeable compounds, and at least one boronic ester compound that enables the association of these two copolymers to be controlled; a method for adjusting the viscosity of a lubricating composition obtained by mixing at least one lubricating base oil and at least two thermoassociative and exchangeable compounds; and the use of a boronic ester compound to adjust the viscosity of a lubricating composition.

Abstract: Compositions obtained by mixing at least one oligomer A1 which is obtained by the copolymerization of at least two monomers functionalized by diol functions with at least one second monomer, and at least one compound A2 comprising at least two boronic ester functions. They have rheological properties which vary significantly depending on the proportion of the compounds A1 and A2 used. Composition obtained by mixing at least one lubricating oil with such a composition of associative and exchangeable polymers, and use of this composition to lubricate a mechanical part.

Abstract: Disclosed is a monophasic lubricating composition including a base oil, an oil chosen from the polyalkylene glycols (PAG) and a phase-change material, in particular water. The monophasic lubricating composition can be used, in particular, for lubricating a vehicle engine. It has improved thermal performance relative to the lubricant compositions of the prior art. It also helps reduce fouling of the engine parts.
