Abstract

A method for suppressing the viscosity of a calcium exotoxin slurry is disclosed. The method comprises adding to the slurry a viscosity-suppressing amount of a copolymer of a vinyl-based monomer and 2-acrylamide-2-methylpropane sulfonic acid or its sodium salt. The copolymer has a weight average molecular weight of from about 1,000 to about 10,000. A slurry comprising calcium exotoxin and about 0.25 to about 2.5 percent by weight of such copolymer is also disclosed.
