Gelled nitric acid blasting composition and method of preparing same
A new method is described for preparing a gelled nitric acid blasting composition stabilized against component separation by addition of a new nitric acid solution-soluble vinyl polymer stabilizer. The new polymer stabilizer may be formed solely of a copolymeric component which immediately gels in the presence of a ferric-ion. Alternately, a preferred polymer stabilizer may be formed of a minor fraction of such a copolymeric component and/or a simple polymer component which immediately gels in the presence of a ferric-ion, taken in combination with a major fraction of a copolymer of a vinyl monomer and an alpha-beta unsaturated acid anhydride and/or a vinyl monomer and a half amide-half ammonium salt of an alpha-beta unsaturated acid.
