Effect of the repartition of the PEG side chains on the adsorption and dispersion behaviors of PCP in presence of sulfate

We studied how the repartition of the negatively charged groups/PEG side chains along the polycarboxylate comb-like copolymers influences the dispersant behavior of these comb copolymers. Performing a RAFT copolymerization allowed providing well defined copolymers differing only in the repartition (...
