Beschreibung
Zusammenfassung:	This invention is concerned with copolymers containing, as copolymerized monomer units, units of aliphatic monoethylenically unsaturated dicarboxylic acid such as maleic acid, and units of at least one comonomer selected from monoethylenically unsaturated monocarboxylic acids, such as acrylic acid, and carboxyl-free monoethylenically unsaturated monomers, such as alkyl esters of acrylic acid. This invention is particularly concerned with the use of low levels of copper ions in an aqueous emulsion polymerization process to promote copolymerization of the above-mentioned monomers at high conversion while maintaining and improving molecular weight control. The copolymers are useful primarily as antiscalants, dispersants, hard surface cleaners, detergent builders and incrustation inhibitors.
