COLLOIDAL DISPERSION OF INORGANIC PARTICLES IN A LIQUID PHASE COMPRISING AN AMPHOLYTIC COPOLYMER |
摘要 |
<p>Colloidal dispersions of inorganic particles in a liquid phase include ampholytic copolymers containing at least one macromolecular chain B and a moiety A bonded to a single end thereof and in which the macromolecular chain B includes cationic units Bc, deriving from cationic monomers Bc and the moiety A is a polymeric or non-polymeric group containing at least one anionic or potentially anionic group; such dispersions may have a positive zeta potential within a pH ranging from 1 to 11.</p> |
