Vf. Kurenkov et al., Flocculating properties and molecular characteristics of copolymer of sodium 2-acrylamido-2-methylpropanesulfonate and N-vinylpyrrolidone, RUS J AP CH, 72(8), 1999, pp. 1450-1453
The kinetics of sedimentation of a kaolin suspension by copolymers of sodiu
m 2-acrylamido-2-methylpropanesulfonate and N-vinylpyrrolidone was studied.
The flocculating effect was determined as influenced by the concentration,
molecular weight, and chemical composition of the copolymer and concentrat
ions of electrolytes (NaCl, CaCl2).
