Abstract:
     The low temperature properties of petroleum distillate fuel with a boiling range of 120 to 500 deg.C, are improved because of the cloud point depression by adding polymer or copolymer of n-alkyl vinyl esters or fumaric acid esters, in which, content of the said ester is at least 25% (weight), in which the n-alkyl ester with 14 to 18 carbon atoms on the average is no more than 10% (weight) and the alkyl ester with more than 18 carbon atoms is also no more than 10% (weight).
