  • Compositions of thermoassociative additives with controlled association and lubricant compositions containing them
    Patent number: 10508250
    Abstract: 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.
    Type: Grant

  • Thermoassociative and exchangeable copolymers, and compositions comprising same
    Patent number: 10377844
    Abstract: A composition results from the mixture of at least one copolymer A resulting from the copolymerization of at least one monomer functionalized by diol functions and at least one compound A2 comprising at last two boronic ester functions. They have rheological properties which are very varied according to the proportion of the A1 and A2 compounds used. The field is that of associative and exchangeable polymers.

  • Lubricating compositions comprising thermoassociative and exchangeable copolymers
    Patent number: 10336960
    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.

  • THERMOASSOCIATIVE AND EXCHANGEABLE COPOLYMERS, AND COMPOSITIONS COMPRISING SAME
    Publication number: 20170008989
    Abstract: A composition results from the mixture of at least one copolymer A resulting from the copolymerisation of at least one monomer functionalised by diol functions and at least one compound A2 comprising at last two boronic ester functions. They have rheological properties which are very varied according to the proportion of the A1 and A2 compounds used. The field is that of associative and exchangeable polymers.
