Abstract

A series of well-defined amphipolar block, graft and statistical copolymers based on the same polar and non-polar monomers were synthesized and investigated for their stabilizing activity against flocculation of solid particles (pigments). The copolymers were characterized and theirstabilizing efficiency was tested with the electrokinetic sonic amplitude (ESA) and the sedimentation method. The measurements revealed that both the type of the copolymer structure and the ratio of polar and non-polar structural elements in the macromolecule play an important role in the adsorption of copolymers on the surface of pigment particles and their stabilization.
