| titleOfInvention | Ethylenimine polymer, aqueous solution of ethylenimine polymer, production process for the same and purifying process therefor |
| abstract | Provided are processes by which an ethylenimine polymer and an aqueous solution thereof can advantageously be produced at low costs in an industrial scale. The ethylenimine polymer can be produced by polymerizing crude ethylenimine obtained by a simple distilling operation from an ethylenimine-containing reaction mixture produced by subjecting ethanolamine to intermolecular dehydration reaction, preferably crude ethylenimine having impurity contents which are controlled in the specific ranges. When the above crude ethylenimine is polymerized in an aqueous medium, capable of being obtained is an aqueous solution of an ethylenimine polymer having a higher molecular weight than that produced by non-solvent polymerization. The ethylenimine polymer can be purified by, for example, adding water thereto, mixing them and then vaporizing and removing water under heating. The aqueous solution of an ethylenimine polymer can be purified by heating and condensing it. |
