Abstract
Water-in-oil emulsion explosive compositions have improved detonation properties, stability and lower viscosity. Bis (alkanolamine or polyol) amide and/or ester derivatives of bis-carboxylated or anhydride derivatized addition polymers are used as the emulsifier. For example, alkanolamine reacted (2:1 ratio) with polyisobutenyl succinic anhydride is found superior to the corresponding 1:1 derivative.
