摘要：The present disclosure is directed to polymers and copolymers of acrylamido-sulfonic acid compounds and their use basically as dispersants for particles contained inaqueous systems. Exemplary of the sulfonic acid compound is 2-acrylamido-2-methylpropane sulfonic acid, or water-soluble salt thereof; and representative of the co-monomers which the acid is copolymerized with can be mentioned, acrylic acid andderivatives thereof, acrylamide and derivatives thereof, vinyl pyrrolidone, etc. Thepolymers and copolymers are specifically useful in dispersing water-insolublecompounds of iron, calcium, magnesium and aluminum and such commonly occurringparticles of slit and clay.
