FIELD: explosives. SUBSTANCE: invention relates to production of explosives, in particular to preparing emulsions of explosives. Emulsifying composition comprises mixture of components from group including: alkenyl(polyisobutylene)succinic anhydride with molecular weight 300-5000, preferably 500-2000, alkenyl(polyisobutylene)succinic anhydride/triethanolamine condensation product, condensation product of alkenyl(polyisobutylene)succinic anhydride with still residue of ethylenediamine or polyamine NH2-(CH2-CH2-NH)12-CH2-CH2-NH2 production, alkenyl(polyisobutylene)succinic anhydride/polyethylenepolyamine condensation product with molecular weight 200-600. For instance, composition contains 4-80% of alkenyl(polyisobutylene)succinic anhydride/triethanolamine condensation product; 10-13% of alkenyl(polyisobutylene)succinic anhydride or its condensation products with ethylenediamine or polyamine, or above-named still residue; and 10-90% of fatty acid-alcohol ester selected from fraction C12-C16 to C21-C25, in particular pentaerythritol, glycerol, or polyglycerol. Emulsifying composition is prepared by mixing required above-indicated condensation products with, for example, fatty acid esters at 20 to 200 C during 0.2 to 2 h. EFFECT: improved performance characteristics of explosives and their storage stability. 2 cl, 2 tbl, 5 ex
