Polyaspartic acid is a non—phosphorus and biodegradable environmental friendly scale and corrosion inhibitor， which becomes the focus in water treatment agent development and research．The technology for synthezising polysuccinimide with L—aspartic acid is widely studied，but the process of polysuccinimide hydrolyzation is seldom studied． The influence of the diferent conditions of polysuccinimide hydrol~rzation on the scale inhibition effect of polyaspartic acid is studied．rI'}le results show the optimal conditions of polysuccinimide hydro—lyzation iS at 10～2O℃ and 100 g／L of sodium hydroxide．
Key words： polyaspartic acid; polysuccinimide; hydrolyzation; scale inh ibition
