摘要:
The invention relates to a composition resulting from the mixture of at least one lubricating oil, at least one statistical copolymer A1, and at least one compound A2 comprising 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 invention also relates to the use of said composition for lubricating a mechanical part. The field of the present invention is that of lubricants.
摘要:
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.
摘要:
The invention relates to a composition resulting 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 of the invention is that of associative and exchangeable polymers.
