Thermoassociative and exchangeable copolymers, composition comprising same

Compositions resulting from the mixing of at least one copolymer A1, resulting from the copolymerization of at least one monomer functionalized by diol functions with at least one styrenic monomer, and at least one compound A2 comprising at least two boronic ester functions. They have very varied rh...

Beschreibung
Zusammenfassung:	Compositions resulting from the mixing of at least one copolymer A1, resulting from the copolymerization of at least one monomer functionalized by diol functions with at least one styrenic monomer, and at least one compound A2 comprising at least two boronic ester functions. They have very varied rheological properties depending on the proportion of compounds A1 and A2 used. Composition resulting from the mixing of at least one lubricating oil with such a composition of associative and exchangeable polymers and use of this composition for lubricating a mechanical part.
