| Abstract: | Polyaspartic acid is a highly biodegradable and new environmental friendly scale and corrosion inhibitor. It is a new type water treatment agent. The recent research accomplishments on the synthesis methods of polyaspartic acid are introduced in this paper. The influence of different synthesis methods and reaction conditions on product conversion and performance is analysed. The primary factors of controlling the mole masscie (molecular weight) and the methods on purifying the product are summarized, and it also points out the future development trend of synthesis process of polyaspartic acid. |
