Novel flocculation system based on 21-arm cationic star polymer

Clay flocculation improved by cationic poly(vinyl alcohol)/anionic polymer dual-component system

“…9. The results showed that the flocculation performance achieved by the CPVA-4/Percol E24 system was not as effective as that achieved by the CPVA-4/Percol 173 system, and this result agrees with our previous work on the dual-component flocculation systems [11].…”

The use of dielectric spectroscopy in the investigation of the effect of polymer choice on the flocculation of polystyrene particles

“…Parameters such as monomeric composition, molecular weight, and cationic charge density have been altered to create flocculants for various purposes. More recently, flocculant modifications have been introduced, such as polymer cross-linking, hydrophobic modification of the polymer backbone [7], and the synthesis of star-shaped polymers [8]. It is generally accepted that adding cationic polymer to a suspension of colloidal particles causes flocculation by charge neutralization, electrostatic patches, or inter-particle bridging [5].…”

Z-RAFT star polymerization of styrene: Comprehensive characterization using size-exclusion chromatography

“…Within this context, the control of macromolecular topology is an ongoing research theme [1]. Among these topologies, star polymers are of special interest since years, because of their distinct rheological behavior arising from their spatial shape both in solution and melt, which is exploited, e.g., in oils and lubricants for automotives [2,3], in adhesives [4], and for flocculation [5]. In addition, star polymers are becoming increasingly important for life sciences, where they e.g.…”
