摘要： An additive mixture, a method for preparing terpolymer, a method for improving the fluidity of fuel oil, a composition comprising the additive mixture, and a fuel composition comprising the additive mixture are provided to have a useful application to improve cold properties of fuel oil. An additive mixture comprises at least one terpolymer(A) of ethylene, propene and at least one ethylene-based unsaturated ester, and at least one additive component of 0.5-20 wt%. The terpolymer contains 6.0-12.0 mol % of structural units derived from at least one ethylene-based unsaturated ester having a C1-C3 alkyl radical, 0.5-4.0 methyl groups derived from propene per 100 aliphatic carbon atoms, and less than 8.0 methyl groups from chain ends per 100 CH2 groups. The additive component is effective as a cold additive for mineral oil, based on the terpolymer. The additive component is selected from at least one copolymer(B1) of ethylene and an ethylene-based unsaturated compound, a comb-shaped polymer(B2), and a mixture(B3) of the copolymer and the comb-shaped polymer. A content of ethylene-based unsaturated compound in the copolymer is higher than a content of the ethylene-based unsaturated ester in the terpolymer by no less than 2 mol%. Further, the ethylene-based unsaturated ester is a vinyl ester of carboxylic acid having 1~4 carbon number.
