1. High adhesion, phahameng absorption sehlopha sa amino ka itšoara joang le hydroxyl sehlopha ho theha hydrogen bond, amine sehlopha ka itšoara joang ka carboxyl sehlopha ho etsa ionic tlamo, amine sehlopha ka boela sa itšoara ka carbon acyl sehlopha ho theha covalent tlamo. Ka nako e ts'oanang, ka lebaka la sebopeho sa eona sa polar (amine) le sehlopha sa hydrophobic (vinyl), se ka kopanngoa le lintho tse fapaneng. Ka matla ana a mangata a tlamang, e ka sebelisoa haholo masimong a ho tiisa, enke, pente, binder joalo-joalo.
2. High-cationic polyvinyl imide e teng ka mokhoa oa polycation ka metsing, e ka khonang ho fokotsa le ho bapatsa lintho tsohle tsa anionic. E boetse e chelate li-ion tsa heavy metal. Ka thepa ea eona e phahameng ea cationic, e ka sebelisoa ho etsa pampiri, kalafo ea metsi, tharollo ea plating, dispersant le masimo a mang.

Polyethylenimine (PEI)ke motsoako oa polymer o nang le mefuta e mengata ea ts'ebeliso, ho kenyelletsa empa e sa felle ho:
1. Ho hloekisa metsi le indasteri ea pampiri. Joalo ka sesebelisoa sa matla a metsi, e sebelisoa pampiring e monyang (joalo ka pampiri ea sefa, pampiri ea enke, pampiri ea ntloana, jj.), e ka ntlafatsang matla a pampiri a metsi le ho fokotsa tšenyo ea ts'ebetso ea pampiri, ha e ntse e potlakisa ho tlhotla ha metsi a makhapetla le ho etsa likhoele tse ntle ho bonolo ho phaphamala.
2. Moemeli oa ho lokisa mebala. E na le matla a matla a tlamang bakeng sa lidae tsa asiti 'me e ka sebelisoa e le ntho e lokisang ha asiti e daea pampiri.
3. Lisebelisuoa tsa ho fetola fiber le ho daea. Bakeng sa kalafo ea fiber, joalo ka lihlomo tsa 'mele, liatlana tse thibelang ho itšeha, thapo, joalo-joalo.
4. Lisebelisoa tsa elektronike. Lefapheng la elektronike, filimi ea imide ea polyethylene e ka sebelisoa e le lera le itšehla thajana, lisebelisoa tse sireletsang le ho koahela lera la likarolo tsa elektronike, joalo-joalo, ka ts'ebetso e ntle ea ho pata le ho hanyetsa mocheso o phahameng.
5. Ho paka lijo. E le thepa ea ho paka lijo, e na le melemo ea ho thibela mongobo, ho hanyetsa khase e ntle, ho se chefo, ho se latsoehe, ho hanyetsa mocheso o phahameng, joalo-joalo, 'me e sebelisoa haholo ho paka nama, likhoho, litholoana, meroho, kofi le lihlahisoa tse ling.
6. Lisebelisoa tsa bongaka. Polyvinylimine e ka sebelisoa lisebelisoa tsa bongaka, lisebelisoa tsa ho hlahloba, liphutheloana tsa bongaka, joalo-joalo, tse kang liaparo tsa bongaka le lifilimi tse pepeneneng tsa bongaka.
7. Sekgomaretsi. E le sekhomaretsi se sebetsang hantle, se sebelisoa ha ho etsoa lifofane, lisebelisoa tsa elektronike, likarolo tsa likoloi joalo-joalo.
8. Lisebelisoa tsa ho hloekisa metsi le li-disperpers. E sebelisoa haholo ho phekola metsi a pampiri, tharollo ea electroplating, dispersant le masimo a mang. Gene carrier. Polyvinylimide ke vector e seng kokoana-hloko bakeng sa phano ea liphatsa tsa lefutso, haholo-holo e loketseng phetiso ea li-plasmids tse ngata.
Holim'a moo,polyethyleniminee boetse e na le litšoaneleho tsa ho khomarela holimo, ho ba le li-adsorption tse phahameng, cation e phahameng, reactivity e phahameng, joalo-joalo, 'me e boetse e sebelisoa haholo masimong a pente, enke, sekhomaretsi, phekolo ea fiber, phekolo ea likhoerekhoere joalo-joalo.
Ka kakaretso, polyvinylimide ke polymer e nang le mefuta e mengata e nang le mefuta e mengata ea lisebelisoa, 'me thepa ea eona e ka fetoloa le ho ntlafatsoa ka ho fetola boima ba limolek'hule, sebopeho le ts'ebetso.
