Abstract: 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.

Abstract translation: 具有高化学均匀性的共聚物，由（A）50〜30重量％的乙烯，（B）50〜70重量％的（甲基）丙烯酸的C 4〜C 24烃基酯，（C）0〜 5重量％的（甲基）丙烯酸和（D）0至10重量％的可共聚单体，可通过将80至60重量％的乙烯，20至40重量％的（甲基）丙烯酸酯 酸和0至10重量％的可共聚单体，在后混合，连续聚合装置中，随后用C4-至C24-烃基聚合物类似地酯化所得共聚物。 本发明的共聚物适用于改善燃料油的冷流性能，用于将冷流改进剂添加剂降低到燃料油中的较低混合温度，以及用于改善包含冷流改进剂添加剂的燃料油的过滤性。

Abstract: The present invention relates to a copolymer obtainable by copolymerization of(A) at least one unsaturated dicarboxylic acid or derivatives thereof, (B) at least one α-olefin having from at least 6 up to and including 20 carbon atoms, (C) optionally at least one C3- to C20-alkyl ester of acrylic acid or methacrylic acid or a mixture of such alkyl esters and (D) optionally one or more further copolymerizable monomers other than monomers (A), (B) and (C), with a molar incorporation ratio of (A):(B):(C):(D) of 1:0.5 to 2.0:0 to less than 0.5:0 to 0.1 followed by the reaction with at least one dialkylamine (E), where the two alkyl radicals in the at least one dialkylamine (E) are independently alkyl radicals having at least 17 up to 30 carbon atoms.
