Abstract
The invention relates to comb polymers and macromonomers based on acrylates prepared by the ATRP (Atom Transfer Radical Polymerization) method. These polymers have an improved capability of dispersing pigments in the given solvent. The invention also relates to compositions comprising the comb polymers and macromonomers dispersible inorganic or organic pigment particles. The compositions are used by applying them to any suitable substrate, for example to metal, wood plastic or ceramic materials.
