摘要

"Composition suitable for use in the form of a dispersant of pigment of graft copolu00ecmeros aqueous dispersion of pigment, and coating composition.Polymeric dispersant for pigments based on a graft copolymer of acrylic copolymer, in which the graft has a weight average molecular weight of about 5000 to 100.000 and comprises a polymer main chain and side chain hidru00f3foba hydrophilic anionic and non ionic bonded to the main chain.These copolymers are useful as dispersants graft in aqueous systems, and are particularly useful in the formulation of the outer coatings containing water for cars and trucks.
