Abstract (en)

[origin: WO2016113229A1] The invention relates to novel compositions of additives resulting from the mixture of at least two thermoassociative and exchangeable copolymers and at least one compound allowing the association of said two copolymers to be controlled. The invention also relates to a lubricating composition resulting from the mixture of at least one lubricating base oil, at least two thermoassociative and exchangeable copolymers and at least one compound allowing the association of said two copolymers to be controlled. The invention also relates to a method for modulating the viscosity of a lubricating composition resulting from the mixture of at least one lubricating base oil, and at least two thermoassociative and exchangeable copolymers, and to the use of a diol compound for modulating the viscosity of a lubricating composition.
