ABSTRACT:
Oil dispersions of water-soluble anionic polymer particles and water-soluble cationic polymer particles are mixed with water to form an aqueous solution containing one polymer in an amount in the range 10 to 40 mole % (moles of anionic groups) and the other polymer in an amount in the range 60 to 90 mole %. The solution is immediately applied to a surface to suppress release of dust from that surface.
