What is POLYETHYLENEIMINE?


Polyethyleneimine (Polyethylenimine, PEI), also known as polyaziridine, is a water-soluble polymer.

This item is a colorless and very thick fluid. Soluble in water, ethanol, hygroscopic, insoluble in benzene, acetone. Any type of sort of experience with sulfuric acid with a pH below 2.4 will cause rainfall. The liquid remedy is favorably charged, as well as the enhancement of formaldehyde generates coagulation.

Polyethyleneimine is separated into 2 kinds: direct and also branched. Direct polyethyleneimine includes all secondary amines, while branched polyethyleneimine has primary, extra in addition to tertiary amine groups. Straight polyethyleneimine of any sort of molecular weight is solid at area temperature level, while branched polyethyleneimine is fluid.

Straight PEI is soluble in warm water or low pH methanol, ethanol or chloroform, yet insoluble in stylish water, benzene, ether as well as also acetone. One end of the polymer chain is a methyl team along with in addition the various other end is an amino group.

Application


1.As a wet strength agent for unsized respiratory paper, retention aid and pulping agent in the paper making process can reduce the pulping degree of the pulp. Improve paper dehydration ability. Make paper dry degree increase 1% ~ 4%. Increase production capacity by 5% ~ 20%.

2.Highly adherent and adsorptive amino groups react with carboxyl groups to form hydrogen bonds. The amino group can react with the carboxyl group to form ionic bonds. Amino can react with carbacyl to form covalent bonds. Polyethylenimines are capable of binding to different substances due to their polar Chemicalbook group (amino) and hydrophobic group (vinyl) structure. The use of these comprehensive binding force, can be widely used in the next, ink, paint, binder and other fields.

3.High cationicity Polyethylenimine exists in water as polymeric cation, which can neutralize and adsorb all anionic substances and chelate heavy metal ions. It can be used in papermaking water treatment, electroplating solution and dispersant.

4.reactive Polyethylenimines can easily react with epoxies, acids, isocyanates and acidic gases due to their highly reactive primary and secondary amines. This property can be used as epoxy resin reactant, aldehyde adsorbent and dye fixator.

5.Under certain conditions, polyethyleneimine strong material can absorb a big quantity of carbon dioxide in damp air, and also the separation procedure is likewise very convenient. Co2 can be completely sequestered in polyethyleneimine strong products, or it can be drawn out for various other fields.

6.The material can be reused and continues to be as high absorptive as ever. Polyethylenimine also has solid bond capacity as well as can successfully make cells attach.
