USE OF COPOLYMERS COMPRISING PHOSPHORUS GROUPS FOR THE PROTECTION OF METALS AND FOR LUBRICATION

The present invention relates to the use, in a lubricating composition for metal, of a copolymer obtained by radical copolymerization of a mixture comprising: - ethylenically unsaturated monomers m1 bearing phosphorus-comprising groups, typically phosphonates, - monomers m2 bearing a hydrophobic cha...
