Progress in the Synthesis and Application of Green Chemicals,Polyaspartic Acid

Polyaspartic acid is a green,biodegradable and environment friendly chemical.The synthesis of polyaspartic acid was systematically introduced.The influence of different synthetic methods and reaction conditions on average molecular weights was summarized.The progress in the application of polyaspartic acid and its derivatives in scale inhibition,viscosity reduction,fertilizer synergism and super-absorbing networks were described in this article.
