  • POUR POINT DEPRESSANTS FOR IMPROVING THE LOW-TEMPERATURE VISCOSITY OF AGED LUBRICATING OIL
    Publication number: 20160348026
    Abstract: The present invention relates to compositions for use as lubricating oil additives. The additive compositions comprise a mixture of alkyl (meth)acrylate copolymers, having distinct monomeric compositions. The additive compositions disclosed herein can be used to improve the low-temperature pumpability of aged lubricating oil, particularly diesel engine oil aged in the presence of biodiesel.

  • Quality control of a functional fluid
    Patent number: 7553673
    Abstract: The present invention describes use of use of a metal compound to control the quality of a functional fluid. Additionally, the present invention concerns a method for controlling the quality of a functional fluid comprising the steps of: adding a metal compound to a component of a lubricant; mixing the component with a base oil; measuring the concentration of the metal compound in the functional fluid; and comparing the expected concentration of the metal compound with the measured concentration.

  • Gradient copolymers, as well as a method for their preparation and their use
    Patent number: 6403745
    Abstract: This invention concerns gradient copolymers, that are obtainable by polymerizing a mixture of olefinically unsaturated monomers that consist of a) 0 to 40% by weight of one or more ethylenically unsaturated ester compounds of formula (I) where R is hydrogen or methyl, R1 means a linear or branched alkyl residue with 1 to 5 carbon atoms, R2 and R3 independently represent hydrogen or a group of the formula —COOR′, where R′ means hydrogen or an alkyl group with 1 to 5 carbon atoms, b) 10 to 98% by weight of one or more ethylenically unsaturated ester compounds of formula (II) where R is hydrogen or methyl, R4 means a linear or branched alkyl residue with 6 to 15 carbon atoms, R5 and R6 independently are hydrogen or a group of the formula —COOR″, where R″ means hydrogen or an alkyl group with 6 to 15 carbon atoms, c) 0 to 80% by weight of one or more ethylenically unsaturated ester compounds of formula (III) where R is hy
