4,4′-Oxydianiline yokhala ndi CAS 101-80-4
Monga chuma chapadera chaumisiri, polyimide ili ndi zabwino za kukana kutentha kwambiri, kukana kwa radiation komanso mphamvu zamakina apamwamba. Amagwiritsidwa ntchito m'mafilimu, zokutira, ulusi, zakuthambo, mafakitale amagetsi ndi magetsi, mapulasitiki okhala ndi thovu ndi ma photoresists. 4,4'-Diaminodiphenyl ether ndi imodzi mwazinthu zazikulu zopangira. Pa nthawi yomweyi, 4,4'-diaminodiphenyl ether ingagwiritsidwenso ntchito kupanga cholumikizira cholumikizira, ndipo imagwiritsidwa ntchito kwambiri m'malo mwa carcinogenic benzidine kupanga utoto wa azo ndi utoto wotakataka. Choncho, 4,4'-diaminodiphenyl ether ndi wapakatikati wokhala ndi mtengo wowonjezera.

1. Ndi imodzi mwazinthu zofunika kwambiri zopangira mapulasitiki apadera apadera monga polyimide, polyetherimide, polyesterimide, polymaleimide, polyaramid ndi ma resins ena okwera kutentha;
2. Amapangidwanso. Zopangira za 3,3',4,4'-tetraaminodiphenyl ether, yomwe ndi monoma yayikulu yokonzekera mndandanda wazinthu zotsekemera za heterocyclic zosagwira polima.
3. Amagwiritsidwanso ntchito ngati zopangira ndi zolumikizira zolumikizirana pakuchita bwino kwambiri kwa epoxy resin, polyurethane ndi ma polima ena opangira.
4. Amagwiritsidwanso ntchito m'malo mwa benzidine wa carcinogenic popanga utoto wa azo, utoto wokhazikika komanso zonunkhira. Pakalipano, pogwiritsa ntchito diaminodiphenyl ether monga zopangira, mitundu yolunjika yamitundu yosiyanasiyana monga yofiira, yofiira kwambiri, mchenga wofiira, wachikasu-bulauni, wobiriwira, imvi, buluu, lalanje wonyezimira ndi wakuda wapangidwa, womwe ungagwiritsidwe ntchito silika, ubweya, thonje, Kupaka utoto wa hemp ndi nsalu zina ndizopambana kuposa utoto wa benzidine potengera kuthamanga kwamtundu komanso kutopa.
