EMULSION EXPLOSIVE COMPOSITIONS CONTAINING A POLY(ALK(EN)YL) SUCCINIC ACID SECONDARY AMINE CONDENSATION PRODUCT, AND THE PREPARATION OF THE EXPLOSIVE

摘要

An emulsion explosive composition comprising a discontinuous phase comprising an oxygen-releasing salt, a continuous water-immiscible organic phase and an emulsifier component comprising a condensation product of a poly[alk(en)yl]succinic acid and/or anhydride with an amine of formula I and wherein either R<1> is selected from the group consisting of hydrogen, alkyl and hydroxyalkyl and R<2> is hydroxyalkyl; or R<1> and R<2> together form a saturated or unsaturated nitrogen containing heterocyclic ring of 5 or 6 constituent ring members, which heterocyclic ring is optionally substituted by alkyl.
