Products Description
Polyethylenimine (PEI) is a hydrophilic cationic polymer widely used as a nonviral nucleotide delivery reagent. Branched PEI can be synthesized by cationic ring-opening polymerization of aziridine. PEI-based particles can also be used as adjuvants for vaccines.
Polyethyleneimine Usage
1. As a wet strength agent for unsized breathing paper, retention aids and beaters in the papermaking process can reduce the beating degree of pulp. Improve paper dehydration ability. The paper dryness is increased by 1%-4%. The production capacity is increased by 5%-20%.
2. Highly adsorbable and adsorbable amino groups react with carboxyl groups to form hydrogen bonds. Amino groups react with carboxyl groups to form ionic bonds. Amino groups react with carbonyl groups to form covalent bonds. Polyethylenimine can bind to different substances because of its polar group (amino) and hydrophobic group (vinyl) structure. These comprehensive bonds can be widely used in the following fields: Dye Fixing Agent inks, coatings, binders, and so on.
3. High cationic polyethyleneimine exists in water as a polymeric cation, which can neutralize and absorb all anionic substances and chelate heavy metal ions. With its high cationic property, it can be used in the field of paper-making water treatment, electroplating solution, and dispersant.
4. Reactive polyethyleneimine can easily react with epoxy, acid, isocyanate compounds and acid gases due to its strong reactivity of primary amine and secondary amine. This property can be used as epoxy resin reactant, aldehyde adsorbent and dye fixative.
