Here’s a concise and clear 5-line definition combining and refining the two inputs:
Polyethyleneimine (PEI) is a versatile, water-soluble polymer made up of repeating amine groups linked by two-carbon aliphatic chains (–CH₂CH₂–).
It exists in branched or linear forms, with each structure offering unique properties.
Due to its strong polycationic nature, PEI is widely used as a flocculant in paper-making. It also plays a critical role in biomedicine, especially in gene delivery and drug formulation. Its high charge density and reactivity make it valuable across various industrial applications.
