Patent

CA 2394660

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.

L'invention concerne des polymères en peigne et des macromonomères basés sur des acrylates préparés au moyen d'un procédé ATRP (polymérisation radiculaire par transfert d'atome). Ces polymères présentent une capacité améliorée de dispersion de pigments dans un solvant donné. L'invention concerne également des compositions comprenant ces polymères en peigne, ces macromonomères et des particules de pigments organiques ou inorganiques dispersables. Ces compositions sont destinées à être appliquées à n'importe quel substrat appropriée, et notamment à des matériaux de métal, de bois,de plastique ou de céramique.
