Description

PolysuccinimideCAS#5608-40-6 is typically a white or off-white powdered solid. It does not dissolve in ordinary organic solvents including water, ethanol and acetone, yet it can partially dissolve or swell in certain strong polar solvents such as dimethyl sulfoxide (DMSO) and N-methylpyrrolidone (NMP).

Parameters

Items	Details
Chemical Name	Polysuccinimide
CAS Number	5608-40-6
Molecular Weight	Usually ranging from several thousand to several hundred thousand, depending on the degree of polymerization
Appearance	Generally white or off-white powder-like solid
Solubility	Insoluble in common organic solvents such as water, ethanol, and acetone. Partially soluble or swellable in some polar solvents like dimethyl sulfoxide (DMSO) and N-methylpyrrolidone (NMP)
Stability	Exhibits good thermal stability and remains stable within a certain temperature range. However, it may undergo degradation or hydrolysis under high-temperature, strong-acid, or strong-alkali conditions

Product Application

Polysuccinimide (CAS#5608-40-6), as a biodegradable polymer material, has a wide range of applications. Its hydrolyzed product, polyaspartic acid, can serve as a phosphorus-free water treatment agent to control scaling and adsorb heavy metals in wastewater. It can also be used as a fertilizer synergist to boost plant growth. In the medical field, it can be modified into a sustained-release carrier for medicines or applied in biocompatible materials. In addition, it can be blended with other polymers to produce degradable plastics, or used as an additive in drilling fluids, a moisturizing agent in cosmetics, and more.
