摘要
The invention provides an explosive composition comprisingA) 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 froma) maleic anhydride,b) one or more olefins having more than 40 carbon atoms, andc) a vinyl ester of carboxylic acids having from 2 to 12 carbon atoms,where the structural units derived from maleic anhydride have been modified by reaction with alcohols, amino alcohols, ammonia or amines.
