Is polyethyleneimine a polymer?
May 25，2026
Yes, polyethyleneimine is definitely a polymer by definition, as it consists of long‑chain molecules formed by repeatedly linking ethylenimine monomers through covalent bonds. It features variable molecular weights ranging from low‑molecular‑weight oligomers to high‑molecular‑weight macromolecules, and its branched or linear structure makes it widely applied in fields such as gene delivery, water treatment, and surface modification.
