    • PURPOSE: Additive compositions are provided to improve cold flow characteristics in fuel oils. The additive compositions are effective in fuel oils having a 90-20 % boiling temperature range as measured in accordance with ASTM D-86 of more than 115 deg.C, and a final boiling point of more than 370 deg.C. CONSTITUTION: The additive composition comprises (a) at least one oil-soluble hydrogenated block diene polymer comprising at least one crystallization block which is obtainable by end-to-end polymerization of a linear diene, and at least one non-crystallizable block being obtainable by 1,2-configuration polymerization of a linear diene by polymerization of a branched diene or by a mixture of such polymerizations; (b) at least one ethylene-unsaturated ester compound; and (c) at least one comb polymer.
    • 目的:提供添加剂组合物以改善燃油中的冷流特性。 该添加剂组合物对根据ASTM D-86测量的沸点温度范围为90-20%且大于115℃,最终沸点高于370℃的燃料油是有效的。 构成:添加剂组合物包含(a)至少一种油溶性氢化嵌段二烯聚合物,其包含至少一种可通过线型二烯的端对端聚合获得的结晶嵌段,并且可获得至少一种不可结晶的嵌段 通过支化二烯的聚合或通过这种聚合的混合物的直链二烯的1,2-构型聚合; (b)至少一种乙烯 - 不饱和酯化合物; 和(c)至少一个梳状聚合物。
