Estimating the term…
The present disclosure relates to novel compositions of additives that result from mixing at least two thermoassociative and exchangeable copolymers and at least one compound for controlling the association of these two copolymers. A lubricant composition results from mixing at least one lubricating base oil, at least two thermoassociative and exchangeable copolymers and at least one compound for controlling the association of these two copolymers. The present disclosure also relates to a process for modulating the viscosity of a lubricant composition that results from mixing at least one lubricating base oil, at least two thermoassociative and exchangeable copolymers; as well as the use of a diol compound for modulating the viscosity of a lubricant composition.
A composition of additives resulting from mixing at least:
A lubricant composition resulting from mixing at least:
A process for modulating viscosity of a lubricant composition, the process comprising:
A method of using at least one compound selected from the 1,2-diols or the 1,3-diols, the method comprising modulating a viscosity of a lubricant composition, the lubricant composition resulting from mixing at least one lubricating oil, at least one polydiol random copolymer A1 and at least one random copolymer A2 comprising at least two boronic ester functions and associating with the polydiol random copolymer A1 by at least one transesterification reaction.
