    • Additives for improving the cold flow behavior of fatty acid esters are provided to set CFPP values to -10 deg.C or -20 deg.C or lower such that the CFPP values remain constant even in the case that the oil is stored for a prolonged period in the temperature range of its cloud point and lower by comprising a copolymer of ethylene and at least one acrylic ester or vinyl ester having a degree of branching of less than 5 CH3 groups per 100 CH2 groups. A fuel oil additive comprises: (A) a copolymer of ethylene and 18 to 35 mol % of at least one acrylic ester or vinyl ester having a C1 to C18-alkyl radical and a degree of branching of less than 5 CH3 groups per 100 CH2 groups; and (B) a comb polymer including structural units of (B1) at least one olefin(first monomer), which has at least one C8 to C18-alkyl radical on the olefinic double bond, and (B2) at least one ethylenically unsaturated dicarboxylic acid(second monomer), which has at least one C8 to C16-alkyl radical bonded through an amide and/or imide group, wherein the parameter Q of a mathematical formula 1 has a value of 23 to 27: wherein w1 is the molar ratio of the respective chain lengths n1 in the alkyl radicals of the first monomer, w2 is the molar ratio of the respective chain lengths n2 in the alkyl radicals of the amide and/or imide groups of the second monomer, n1 are the respective chain lengths in the alkyl radicals of the first monomer, n2 are the respective chain lengths in the alkyl radicals of the amide and/or imide groups of the second monomer, i is the serial variable for the chain lengths in the alkyl radicals of the first monomer, and j is the serial variable for the chain lengths in the alkyl radicals of the amide and/or imide groups of the second monomer.
    • 提供用于改善脂肪酸酯的冷流行为的添加剂以将CFPP值设定为-10℃或-20℃或更低,使得CFPP值即使在油被长时间储存​​的情况下也保持恒定 通过包含乙烯和至少一种具有小于5个CH3基团/ 100个CH2基团的支化度的丙烯酸酯或乙烯基酯的共聚物而在其浊点的温度范围内降低。 燃料油添加剂包括:(A)乙烯和18至35摩尔%的至少一种具有C1至C18-烷基的丙烯酸酯或乙烯基酯和每100个CH 2少于5个CH 3基团的支化度的共聚物 组; 和(B)包含(B1)至少一种烯烃(第一单体)的结构单元的梳状聚合物,其在烯属双键上具有至少一个C 8-18烷基,和(B2)至少一种烯属不饱和二羧酸 具有通过酰胺和/或酰亚胺基团键合的至少一个C 8至C 16 - 烷基的酸(第二单体),其中数学式1的参数Q具有23至27的值:其中w1是摩尔比 在第一单体的烷基中各个链长度n1的w2是第二单体的酰胺和/或酰亚胺基团的烷基中各个链长度n2的摩尔比,n1是 第一单体的烷基n2是第二单体的酰胺和/或酰亚胺基团的烷基中各自的链长,i是第一单体的烷基中链长度的连续变量,以及 j是链长度的串行变量 在第二单体的酰胺和/或酰亚胺基团的烷基中。
