  • Polyalkyl(meth)acrylates for improving fuel economy, dispersancy and deposits performance
    Patent number: 11518955
    Abstract: Polyalkyl(meth)acrylates contain specified amounts of long-chain alkyl (meth)acrylates and functional monomers. Lubricant compositions can contain such polyalkyl(meth)acrylates, and the polyalkyl(meth)acrylates can be used as viscosity index (VI) improvers with good fuel economy as well as soot-dispersant function. The polyalkyl(meth)acrylates can provide equal or even unproved deposits in lubricant compositions, especially in engine oil (EO) compositions.
    Type: Grant
    Filed: March 18, 2020
    Date of Patent: December 6, 2022
    Assignee: Evonik Operations GmbH
    Inventors: Katrin Schoeller, Fabian Ziegler, Boris Eisenberg, Dmitriy Shakhvorostov, Klaus Schimossek
  • Random copolymers for use as base oils or lubricant additives
    Patent number: 11453837
    Abstract: The invention relates to random copolymers comprising monomers derived from conjugated dienes and alkyl (meth)acrylates, a method for manufacturing the copolymers, lubricant compositions comprising the copolymers, and the use of the copolymers as additives for lubricant compositions or as a base oil for lubricant compositions. The copolymers are favorably used for driving system lubricating oils, hydraulic oils, engine oils and industrial oil formulations.

  • Antiwear copolymers and lubricant compositions
    Patent number: 11359042
    Abstract: The present invention relates to copolymers, to a method for the preparation of these copolymers, to the use of these copolymers for reducing wear in a lubricant composition, to lubricant compositions comprising these copolymers, and to the use of these lubricant compositions as an automatic transmission fluid, a continuously variable transmission fluid, an engine oil, a gear oil, or a hydraulic oil.
