    摘要： A copolymer with high chemical homogeneity, consisting of (A) 50 to 30% by weight of ethylene, (B) 50 to 70% by weight of C4- to C24-hydrocarbyl ester of (meth)acrylic acid, (C) 0 to 5% by weight of (meth)acrylic acid and (D) 0 to 10% by weight of copolymerizable monomers, obtainable by polymerizing a mixture of 80 to 60% by weight of ethylene, 20 to 40% by weight of (meth)acrylic acid and 0 to 10% by weight of copolymerizable monomers in a backmixing, continuous polymerization apparatus, and subsequently polymer-analogously esterifying the resulting copolymer with C4- to C24-hydrocarbinols. The inventive copolymer is suitable for improving the cold flow properties of fuel oils, for lowering the lower mixing temperature of cold flow improver additives into fuel oils, and for improving the filterability of fuel oils comprising cold flow improver additives.

    摘要： The use of a mixture comprising (A) 5 to 95% by weight of at least one oil-soluble polar nitrogen compound which can interact with paraffin crystals in middle distillate fuels under cold conditions, and (B) 5 to 95% by weight of at least one oil-soluble aliphatic compound with an alkyl or alkenyl chain having at least 8 carbon atoms, obtainable from aliphatic mono- or dicarboxylic acids having 4 to 300 carbon atoms or derivatives thereof with mono- or polyamines or with alcohols, for lowering the cloud point in middle distillate fuels which, before the addition of additives, have a CP of −8.0° C. or lower by at least 1.5° C. compared to the unadditized middle distillate fuel at a dosage of the mixture of 50 to 300 ppm by weight, with no simultaneous deterioration in the response behavior for the lowering of the cold filter plugging point on addition of cold flow improvers.
