Abstract

The invention provides an explosive composition consisting ofA) an oxygen-donating constituent, which forms a disperse phase,B) an organic constituent, which forms a dispersion phase, andC) at least one emulsifier,wherein the emulsifier includes a copolymer comprising, in random or regular order, structural units derived from maleic anhydride and from one or more olefins having more than 40 carbon atoms, where the structural units derived from maleic anhydride have been modified by reaction with alcohols, aminoalcohols, ammonia or amines.
