Polyasparfic acid is a biomacromolecule material. It possesses anti-filthy, corrosion inhibition, dispersion, chelation, anti-moisture and so on many kinds of functions, became the green chemical which increased day by day in the global sales volume. The market prospect of polyaspartic acid is broad in recent years and economic efficiency and the social efficiency were considerable. Because polyaspartic acid include peptide key and carboxyl group and so on active group unique features, it widely applies in domains of, such as chemical fertilizer, agricultural chemicals, industry water treatment, metal cutting compound, surface active agent, and daily use chemicals. This article introduced production method, the technology to progress, the application domain and the market prospect of polyaspartic acid, and put forward some proposals to the domestic industry development for polyaspartic acid.
