The invention provides an explosive composition comprising A) an oxygen-donating constituent, which forms a disperse phase, B) an organic constituent, which forms a dispersion phase, and C) at least one emulsifier, wherein the emulsifier includes a copolymer comprising, in random or regular order, structural units derived from a) maleic anhydride, b) one or more olefins having more than 40 carbon atoms, and c) 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.

1. An explosive composition comprising A) an oxygen-donating constituent, which forms a disperse phase, B) an organic constituent, which forms a dispersion phase, and C) at least one emulsifier, wherein the emulsifier includes a copolymer comprising, in random or regular order, structural units derived from a) maleic anhydride, b) one or more olefins having more than 40 carbon atoms, and c) 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. 2. An explosive composition as claimed in claim 1, wherein the composition comprises an alternating copolymer of a vinyl ester of carboxylic acids having from 2 to 12 carbon atoms, at least one olefin having ca. 40-500 carbon atoms and maleic anhhydride which has been modified with a) alcohols, b) amino alcohols, c) ammonia or d) amines. 3. An explosive composition as claimed in claim 1 wherein the olefin is a polymer of short-chain olefins having 2-6 carbon atoms. 4. An explosive composition as claimed in claim 3, wherein the short-chain olefin is butene or a butene isomer. 5. An explosive composition as claimed in claim 1, wherein the olefin used is polyisobutylene. 6. An explosive composition as claimed in claim 1, wherein a C8-C12-vinyl ester is used as constituent c) of the emulsifier copolymer. 7. An explosive composition as claimed in claim 1, wherein the polymer of maleic anhydride, vinyl esters and olefins is reacted with an amino alcohol to give the half-ester or a salt of the half-ester. 8. An explosive composition as claimed in claim 7, wherein the amino alcohol is 2-dimethylaminoethanol or 2-diethylaminoethanol. 9. An explosive composition as claimed in claim 1, wherein the coemulsifier used is a derivative of an alkenylsuccinic anhydride. 10. An explosive composition as claimed in claim 9, wherein the derivative of an alkenylsuccinic anhydride is a derivative of a polyisobutenylsuccinic anhydride.
