Cationic acrylamide copolymers and terpolymers as flocculants for model aqueous suspensions (in English)

Polimery 2010, No 4, 299


DOI: dx.doi.org/10.14314/polimery.2010.299

Summary

Cationic acrylamide copolymers with diallyldimethylammonium chloride and terpolymers of the both monomers with N-vinylformamide were synthesized, characterized by capillary viscometry and their flocculation efficiency evaluated by extinction, sludge volume and solid matter recovery measurements. The polymerization reactions were carried out either as thin-layer processes in aqueous solutions or as microsuspension polymerization. The results from the numerous flocculation tests performed on model aqueous suspensions of fine coal, colloidal silica and talc have been presented and discussed. Flocculation efficiency was determined taking into account the type and dose of the used copolymer.


Key words: acrylamid cationic copolymers and terpolymers, diallyldimethylammonium chloride, N-vinylformamide, flocculants, flocculation efficiency
