摘要:
The present invention relates to the use of a liquid composition as heat transfer fluid, characterized in that the liquid composition comprises polymers derived from at least an ethylenically unsaturated monomer or a mixture of ethylenically unsaturated monomers. Preferably, the liquid composition is used as a heat transfer fluid for electrical equipment.
摘要:
The present invention describes a composition comprising: (A) at least one polyalkyl (meth) acrylate polymer having a number average molecular weight M n 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 antioxidant; (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.
摘要:
The present invention relates to copolymers comprising ester groups and having at least one nonpolar segment P and at least one polar segment D, the polar segment D having at least 8 repeat units and the proportion by weight of dispersing repeat units in the polar segment D being at least 30%, based on the weight of the polar segment D, wherein the copolymer comprising ester groups is obtainable by NMP (nitroxide mediated polymerization). The invention further relates to lubricant oils having improved friction properties and comprising said copolymers.
摘要:
The present invention relates to a lubricant composition for a process for reducing the paraffin content of mineral oil compositions, by providing a mineral oil composition with a dewaxing aid, cooling to form a paraffin precipitate and at least partly removing the paraffin precipitate formed. The dewaxing aid used is a copolymer mixture comprising at least three copolymers, the copolymers differing in the composition of the repeat units.
摘要:
The present invention relates to a transmission oil formulation comprising a base oil and a copolymer obtained by radical polymerization from a monomer composition.taineThe invention also relates to the use of the transmission oil formulation as transmission oil for reducing fuel consumption by vehicles.
