Uses and synthesis of polyethyleneimine Liquid

polyethyleneimine Liquid is a typical water-soluble polyamine, which has a wide range of applications due to the abundant nitrogen atoms in the macromolecular chain that make polyethyleneimine highly protonophilic.

polyethyleneimine CAS 25987-06-8 is a water-soluble polymer produced by polymerisation of ethyleneimine. Polyethyleneimine Raw Materials is not a fully linear polymer, but is a partially branched polymer containing primary, secondary and tertiary amines.

Applications / Functions of polyethyleneimine Liquid

1. polyethyleneimine Raw Materials are used as cationic flocculants, industrial wastewater treatment agents, detergents, adhesives, and water treatment agents.
2. Detergents, adhesives, water treatment, inks, dyestuffs, cosmetics and paper industry, adhesion aids, laminating primers, colour fixing agents, flocculants, cationic dispersants, stabilizers, surfactants, chelating agents, and aldehyde and oxide scavengers.
3. 

polyethyleneimine Liquid is used as a primary brightener, grain refiner and improves dispersing ability in alkaline zinc plating, copper plating, tin and tin alloy plating, aluminium plating and aluminium alloy plating.

Physicochemical Property of polyethyleneimine Liquid

• 1、High adhesion and adsorption property
• 2、High cationicity
• 3、Reactivity
• .

Production methodprocess of polyethyleneimine Liquid

Polyethyleneimine Liquid is firstly esterified by ethanolamine and sulfuric acid, and then processed to get ethyleneimine. Then polymerise the polyethyleneimine under acidic condition.
