Based on the concept of hyperdispersant and the actual requirenents of the coatings manufacturers，a professional hyperdispersant was designed and prepared，with solvation chain of poly（adipoyl-hexanediol-phthaloyl）（ AA-HG-PA）， and the anchoring functional groups was selected from N，N-dinethylaninopropylamine，N，N-dinethylethanolamine， and polyethene polyamine. The results showed that the fineness of the coatings could be reduced down to about 15 μm，and the dispersion system was stable，when the mononer ratio insolvation chain was n（AA）∶n（PA）∶n（HG）=8∶4∶13，and the molecular weight 3 000. When polyethylene polyamine anchor group was used，the viscosity-reducing effect of the coatings and the color shade and gloss of the coatings film were similar to that of imported product. The
storage stability of the hyperdispersant met the requirement of industrial application.
