4,4′-Oxydianiline yokhala ndi CAS 101-80-4
4,4-diaminodiphenyl Ether (4'-ODA) CAS 101-80-4,4,4' -oxydianiline ndi chinthu chofunikira cha aromatic diamine organic. Chifukwa cha kukhalapo kwa magulu awiri a amino (-NH₂) ndi ether bond imodzi (-O-) mu molekyulu yake, 4,4'-DPE ili ndi reactivity yabwino kwambiri komanso kukana kutentha ndipo ndi monomer yofunika kwambiri popanga zinthu za polima zapamwamba.
Monga chida chapadera cha uinjiniya, polyimide ili ndi ubwino wokana kutentha kwambiri, kukana kuwala kwa dzuwa komanso mphamvu yayikulu yamakina. Diaminodiphenyl ether imagwiritsidwa ntchito m'mafilimu, zokutira, ulusi, ndege, mafakitale amagetsi ndi zamagetsi, mapulasitiki okhala ndi thovu ndi ma photoresists. 4,4'-Diaminodiphenyl ether ndi imodzi mwa zipangizo zazikulu zopangira. Nthawi yomweyo, 4,4'-diaminodiphenyl ether ingagwiritsidwenso ntchito popanga cholumikizira cholumikizira, ndipo imagwiritsidwa ntchito kwambiri m'malo mwa benzidine yomwe imayambitsa khansa kuti ipange utoto wa azo ndi utoto wochitapo kanthu. Chifukwa chake, 4,4'-diaminodiphenyl ether ndi yapakatikati yokhala ndi phindu lalikulu.

1. 4'-ODA ndi imodzi mwa zipangizo zofunika kwambiri zopangira mapulasitiki atsopano apadera monga polyimide, polyetherimide, polyesterimide, polymaleimide, polyaramid ndi ma resins ena olimbana ndi kutentha kwambiri;
2. 4'-ODA imapangidwanso. Zinthu zopangira za 3,3', 4,4'-tetraaminodiphenyl ether, yomwe ndi monomer yayikulu yokonzekera zinthu zingapo za polymer zotsutsana ndi kutentha za heterocyclic.
3. 4,4'-DPE imagwiritsidwanso ntchito ngati zopangira komanso cholumikizira cholumikizira cha epoxy resin, polyurethane ndi ma polima ena opangidwa omwe sagwira ntchito bwino kutentha.
4. 4,4'-DPE imagwiritsidwanso ntchito m'malo mwa benzidine yomwe imayambitsa khansa popanga utoto wa azo, utoto wochitapo kanthu komanso zonunkhira. Pakadali pano, pogwiritsa ntchito diaminodiphenyl ether ngati zopangira, utoto wolunjika wamitundu yosiyanasiyana monga wofiira wowala, wofiira wonyezimira, wofiira wamchenga, wachikasu-bulauni, wobiriwira, imvi, buluu, lalanje wonyezimira ndi wakuda wapangidwa, womwe ungagwiritsidwe ntchito pa silika, ubweya, thonje. Kupaka utoto wa hemp ndi nsalu zina ndikopambana kuposa utoto wa benzidine pankhani ya kufulumira kwa mtundu komanso kuchuluka kwa kutopa.
