Copolymers of an acrylic acid and alkoxyalkyl acrylate as scale inhibitors, dispersants and stabilizers

摘要

Water is treated with copolymers of an acrylic acid and an alkoxyalkyl acrylate which are devoid of acrylamide or methacrylamide. The copolymers are effective as a scale inhibitors in the presence or absence of metal ions, particularly iron, manganese and zinc ions; as stabilizers for the metal ions; and as dispersants for particulate matter, particularly for particulates such as iron oxide, clay, silt, and mixtures thereof.
