Beschreibung
Zusammenfassung:	As a fuel oil additive, an ethylenic copolymer is provided which is derived from: (a) ethylene, and (b) at least one monomer selected from the group consisting of vinyl esters of saturated carboxylic acids, ethylenically unsaturated mono- or di-carboxylic acids and esters thereof which are represented by the general formula: wherein R1 represents hydrogen or a methyl group, R2 represents the group -OCOR4 or -COOR4 in which R4 represents hydrogen or an alkyl group having 1 to 18 carbon atoms, and R3 represents hydrogen or the group -COOR4 in which R4 has the same significance as above, having a number average molecular weight of less than 1,000 and a (b) component content of 1 to 25 mol %, and containing 2 to 10 alkyl branches per 100 methylene groups. Addition of the copolymer to a fuel oil provides a modified fuel oil having improved plugging resistance and having improved flowability.
