초록

A novel PIBSA-based surfactant is provided which has particular utility in the manufacture of water-in-oil explosive emulsions. The surfactant comprises the esterification product of polyalk(en)yl succinic anhydride and an adduct of the formula: [Figure] where R1 is H or -CH2-CH2-OH and R2 is selected from the group consisting of an acyl group containing 8-20 carbon atoms and a hydroxy ethyl ester of a mono- or di-carboxylic acid containing from 8-25 carbon atoms. The compound can be distinguished from the prior art PIBSA-based surfactants by virtue of t...
