Patent ID: 7429555

Claim:
A lubricating grease comprising at least one thickening agent, at least one lubricating oil, and at least one polymeric structure improver that can be obtained by polymerization of monomer compositions, which comprise a) 0 to 40 wt %, relative to the weight of the monomer compositions for synthesis of the polymeric structure improvers, of at least one (meth)acrylate of formula (I) in which R represents hydrogen or methyl, R 1 denotes a straight-chain or branched alkyl moiety having 1 to 5 carbon atoms, b) 40 to 99.99 wt %, relative to the weight of the monomer compositions for synthesis of the polymeric structure improvers, of at least one (meth)acrylate of formula (II) in which R represents hydrogen or methyl, R 2 denotes a straight-chain or branched alkyl moiety having 6 to 30 carbon atoms, c) 0.01 to 5 wt %, relative to the weight of the monomer compositions for synthesis of the polymeric structure improvers, of monomers containing acid groups or salts thereof, d) 0 to 59.99 wt %, relative to the weight of the monomer compositions for synthesis of the polymeric structure improvers, of comonomer.
