    摘要: Cold flow properties of distillate fuel such as diesel fuel are improved by the addition of a small amount of a tetrapolymer of ethylene, a C.sub.3-32 .alpha.-olefin (e.g. hexene-1), vinyl ester of a C.sub.1-12 aliphatic monocarboxylic acid (e.g. vinyl acetate) and a vinyl substituted aromatic hydrocarbon (e.g. styrene) having an average molecular weight of 2,000-5,000.
