Abstract:
1. A process for producing a lubricating grease, comprising: adding a polymeric structure improver to a dispersion which has a grease structure, wherein the dispersion comprises at least one thickener and at least one lubricating oil, and wherein the polymeric structure improver is added in the form of a composition which is a liquid at 25° C., and wherein the polymeric structure improver is obtained by polymerizing a monomer composition comprising: a) 0 to 40% by weight, based on the weight of the monomer compositions for preparing the polymeric structure improvers, of one or more ethylenically unsaturated ester compounds of the formula (I) b) 50 to 100% by weight, based on the weight of the monomer compositions for preparing the polymeric structure improver, of one or more ethylenically unsaturated ester compounds of formula (II) c) 0.01 to 20% by weight, based on the weight of the monomer compositions for preparing the polymeric structure improvers, of acid-bearing monomers or salts thereof comprising at least one monomer selected from the group consisting of methacrylic acid and acrylic acid or salts thereof.
