ABSTRACT:
Terpolymers of maleic anhydride, acrylamide or methacrylamide and a third monomer consisting of octene, styrene and the like.
Copolymers of maleic anhydride and acrylamide or methacrylamide.
Use of the hydrolyzed form of the terpolymer as a scale control agent.
Novel process employing a mixture of aromatic and ketonic solvent and a temperature of at least 120.degree. C. which renders the polymers of the invention insoluble in water at ambient temperature.
