ABSTRACT:
Water-soluble (meth)acrylic acid/methallysulfonate copolymers, containing less than 20% by weight of the methallylsulfonate comonomer, are well suited as scale inhibitors for aqueous environments, especially those comprising essentially equal amounts by weight of both acrylic and methacrylic acids.
