Application 1. Highly adherent and adsorptive amino groups can react with carboxyl groups to form hydrogen bonds. Amino groups can react with carboxyl groups to form ionic bonds. Amino groups can react with carbonyl groups to form covalent bonds. Poly(ethylenimine) due to its polar group (amino group) And hydrophobic (vinyl) structure, can be combined with different substances. With these combined strength, can be widely used in the field of inks, coatings, adhesives, etc.?
2. Highly cationic Poly (ethylenimine) in water In the presence of polymeric cations, it can neutralize and adsorb all anionic substances, and can also chelate heavy metal ions. With its high degree of cationicity, it can be used in paper water treatment, electroplating bath, dispersant field.
3. Reactive Poly(ethylenimine) Due to the highly reactive primary and secondary amines, it can easily react with epoxy, acid, isocyanate compounds and acid gases. This property can be used as epoxy Resin reactant, aldehyde adsorbent and dye fixing agent.
