Primary amine-containing polymers useful as scale inhibitors

Processes for inhibiting scale produced during wet process phosphoric acid production by adding a scale-inhibiting amount of a reagent having a primary amine-containing polymer to at least one stage of a wet process phosphoric acid production process are provided herein, wherein said primary amine-containing polymer includes one or more organic moieties that reduce the polymer's solubility in an aqueous environment as compared to its native form, thereby reducing or preventing scale in the wet process phosphoric acid production process.
