  • COMPOSITION TO IMPROVE LOW TEMPERATURE PROPERTIES AND OXIDATION STABILITY OF VEGETABLE OILS AND ANIMAL FATS
    Publication number: 20150232783
    Abstract: The present invention describes a composition comprising: (A) at least one polyalkyl (meth) acrylate polymer having a number average molecular weight Mn of from 15000 to 75000 g/mol; (B) at least one ethylene vinyl acetate copolymer comprising units being derived from at least one alkyl (meth) acrylate having 1 to 30 carbon atoms in the alkyl residue; (C) a phenolic type anti-oxidant; (D) a mixture stabilizer; and (E) a glycol ether solvent. The composition is useful as cold flow improver and oxidation stabilizer in vegetable oils and animal fats.

  • METHOD OF PROVIDING HIGH COEFFICIENTS OF FRICTION ACROSS OIL-LUBRICATING FRICTION CLUTCHES
    Publication number: 20140274835
    Abstract: The invention concerns a method of increasing the dynamic coefficient of friction in an oil-lubricated friction clutch by using a lubricating oil containing at least one specific copolymer, the presence of which develops higher dynamic friction levels in the clutch.

  • USE OF COMB COPOLYMERS FOR IMPROVING SCUFFING LOAD CAPACITY
    Publication number: 20120258899
    Abstract: The present invention relates to the use of comb polymers comprising, in the main chain, repeat units derived from polyolefin-based macromonomers with a molecular weight of at least 500 g/mol, and repeat units derived from low molecular weight monomers with a molecular weight less than 500 g/mol, for improving the load-bearing capacity of hydraulic fluids. Furthermore, the present invention describes new hydraulic fluids.

  • POLYALKYL (METH)ACRYLATE COPOLYMERS HAVING OUTSTANDING PROPERTIES
    Publication number: 20120046207
    Abstract: The present invention relates to copolymers obtainable by polymerizing a monomer composition composed of a) 0% to 40% by weight of one or more ethylenically unsaturated ester compounds of the formula (I) in which R is hydrogen or methyl, R1 is a linear or branched alkyl radical having 1 to 5 carbon atoms, R2 and R3 independently are hydrogen or a group of the formula —COOR?, in which R1 is hydrogen or an alkyl group having 1 to 5 carbon atoms, b) 10% to 99.
