Polysuccinimide (PSI) is a functional polymer synthesized through the thermal polycondensation of aspartic acid. It serves as a key intermediate in the production of polyaspartic acid (PASP), an environmentally friendly and biodegradable water treatment chemical.Due to its reactive imide structure, Polysuccinimide can be easily hydrolyzed or modified to produce a range of functional derivatives. It is widely used in water treatment, oilfield chemicals, detergents, and agricultural formulations.

Water Treatment Industry
Polysuccinimide is mainly used as an intermediate to produce polyaspartic acid (PASP), which functions as:
Scale inhibitor
Corrosion inhibitor
Dispersant
Environmentally friendly water treatment agent
PASP derived from PSI is widely applied in cooling water systems, boilers, desalination plants, and industrial circulating water systems.
