Product Description
Polysuccinimide (CAS#5608-40-6) typically appears as a white or off-white powder. It is insoluble in common organic solvents like water, ethanol, and acetone, but can partially dissolve or swell when exposed to stronger polar solvents, including dimethyl sulfoxide (DMSO) and N-methylpyrrolidone (NMP).

Product Application
Polysuccinimide (CAS#5608-40-6) is a biodegradable polymer with versatile applications. Its hydrolysis byproduct, polyaspartic acid, serves as a phosphorus-free water treatment agent, effectively inhibiting scale formation and adsorbing heavy metals in wastewater. It can also act as a fertilizer enhancer to support plant growth. In medicine, it can be modified into sustained-release drug carriers or utilized in biocompatible materials. Additionally, it can be blended with other polymers to create biodegradable plastics, or used as an additive in drilling fluids, as well as a moisturizing agent in cosmetics.
