Description and Uses

Branched polyethyleneimine (PEI) is widely used in many applications due to its polycationic character. Unlike its linear equivalent, branched PEI contains primary, secondary, and tertiary amines. Primarily utilized in industrial applications, high molecular weight PEI has been used as a flocculating agent, textile coating, adhesion promoter, enzyme carrier, and as a material for CO₂ capture.
