More Information
Summary:FIELD: polymer production. ^ SUBSTANCE: invention relates to water-soluble powder polymer compositions useful as flocculants for dehydration of solids-containing slurries or sludges. Compositions are prepared via continuous polymerization of at least one unsaturated monomer, wherein at least one polymerization-affecting parameter is varied in accordance with a repetitive scheme. For instance, monomer concentration, molecular weight regulator amount, monomer solution pH value, and/or monomer solution composition can be varied. ^ EFFECT: expanded flocculation possibilities and reduced sensitivity to composition of fluids to be treated. ^ 14 cl, 4 ex
