Polyaspartic acid is a new type of highly biodegradable and environmental friendly water treatment agent. The polymerization methods of polyaspartic acid were introduced and the main influence factors on molecular weight, yield and colour of it were analysed; the reactive mechanisms in each manufacture method were also described. In addition, the recent research accomplishments on the performance of polyaspartic acid were summarized in this paper.
