Abstract: AMINOALYLENE PHOSPHONATES CONTAINING SULFUR, OXYGEN, SULFOXIDE OR SULFONE GROUPS AND THEIR USE AS CORROSION INHIBITORS IN AQUEOUS SYSTEMS. IT HAS BEEN DISCOVERED THAT COMPOUNDS OF THIS NATURE NOT ONLY YIELD SATISFACTORY ANODIC INHIBITION, BUT ALSO VERY DESIRABLE CATHODIC CORROSION INHIBITION WHEN ADDED TO AQUEOUS SYSTEMS IN AN EFFECTIVE AMOUNT, E.G. RANGING FROM 1 TO 1000 PARTS PER MILLION PARTS BY WEIGHT OF THE AQUEOUS SYSTEM.

Abstract: The present disclosure is directed to novel water-soluble cationic polymers and their use either alone or in conjunction with coagulant aids to flocculate or coagulate matter suspended in aqueous systems. The novel polymer is prepared by reacting an alkylene polyamine with an epihalohydrin under specific conditions which include the incremental reaction of the epihalohydrin to fully react with the epihalohydrin and attain a polymer of uniform viscosity.

Abstract: The present disclosure is directed to polymers and copolymers of acrylamido-sulfonic acid compounds and their use basically as dispersants for particles contained in aqueous 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 and derivatives thereof, acrylamide and derivatives thereof, vinyl pyrrolidone, etc. The polymers and copolymers are specifically useful in dispersing water-insoluble compounds of iron, calcium, magnesium and aluminum and such commonly occurring particles of slit and clay.
