Polyethylenimine CAS 25987-06-8 with MW800 MW 3500

What Is Polyethylenimine CAS 25987-06-8

Polyethylenimine is a typical water-soluble polyamine. Due to the rich nitrogen atoms on the macromolecular chain, polyethylenimine has strong protophilicity, so it has a wide range of applications, such as as as flocculant in papermaking and pulping field, adsorption of metal ions in water treatment field, and cationic polymer non viral gene carrier in medical field, etc.
