Patent

CA 2352470

A polymeric dispersant for pigments based on an acrylic graft copolymer wherein the graft copolymer has a weight average molecular weight of about 5,000- 100,000 and comprises a hydrophobic polymeric backbone and discrete anionic and nonionic hydrophilic side chains attached to the backbone. These graft copolymers are useful as dispersants in aqueous systems, and are particularly useful in formulating exterior water borne coatings for automobiles and trucks.
