COLLOIDAL DISPERSION OF INORGANIC PARTICLES IN A LIQUID PHASE COMPRISING AN AMPHOLYTIC COPOLYMER

摘要

The colloidal dispersion of the invention is a dispersion of inorganic particles in a liquid phase of the invention which contains an ampholytic copolymer comprising at least one macromolecular chain B and a part A bonded to a single end of at least one macromolecular chain B and in which the macromolecular chain B comprises cationic units Bc, deriving from cationic monomers Bc and the part A is a polymeric or non-polymeric group comprising at least one anionic or potentially anionic group. This dispersion may have a positive zeta potential within a pH range between 1 and 11.
