4,4'-oxydiphthhalic anhydride (OMPA) yog ib qho kev siv khoom nruab nrab ntau yam uas muaj ntau cov ntawv thov hauv ntau cov khoom lag luam. Odpa CAS 1823-59-2 yog hmoov dawb crystalline uas yog synthesized los ntawm cov tshuaj tiv thaiv ntawm phthalic anhydride thiab phenols.
4,4'-oxydiphalic anhydrid li 1823-59-2 yog qhov tseem ceeb nruab nrab hauv kev tsim cov kev ua haujlwm siab polymers xws li polyime, thiab epoxy resins. Cov neeg polymers muaj cov tshuab polymers muaj ntau, thiab tshuaj lom neeg, ua rau lawv muaj txiaj ntsig zoo xws li aerospace, khoom siv hluav taws xob, thiab kev lag luam hauv tsheb.
Polyimides yog qhov kub-tiv taus polymers uas tau siv hauv cov ntawv thov. Qee cov piv txwv ntawm cov ntawv thov no suav nrog cov kabmob, cov zog, thiab cov ntsaws ruaj ruaj. 4,4'-oxydiphalic anhydrid li 1823-59-2 yog qhov tseem ceeb hauv PMDA-ODA, BPDA-ODA, thiab BPDA-PDA.
Epoxy Resins tau siv los ua cov nplaum, cov xim pleev xim, thiab kev sib xyaw ua ntau yam lag luam.ODPA CAS 1823-59-2yog siv nyob rau hauv kev tsim cov khoom siv epoxy xws li bisphenol ib hom epoxy resins thiab novolac hom epoxy resins. Cov txheej txheem no muaj cov khoom zoo, muaj zog, thiab tshuaj lom neeg ua kom haum rau kev siv hauv kev tsim kho, kev lag luam hluav taws xob, thiab kev lag luam hluav taws xob.
Polyesters yog lwm hom polymer uas tuaj yeem tsim tau siv OPPA ua ib nrab. Cov neeg polymers muaj lub zog siab, ua kom muaj zog, ua rau lawv muaj txiaj ntsig zoo xws li cov ntaub ntawv ntim khoom xws li cov ntaub ntawv ntim khoom, thiab txheej txheej.
Odpa tseem siv nyob rau hauv kev tsim cov tshuab yas xws li Ortho-phtical Esters. Cov kab yas no tau ntxiv rau cov polymers kom nce lawv yooj thiab siv tau. Odpa-based planizers muaj cov kev ua tau zoo tsawg-kub thiab tau siv hauv cov ntawv thov uas yooj yog qhov ntsuas tseem ceeb.
Ntxiv rau nws siv hauv kev tsim cov polymers thiab cov tshuab yas,4,4'-oxydiphthhalic anhydrid li cas 1823-59-2Yog siv los ua cov nplaim taws retardant hauv kev tsim cov hluav taws xob thiab khoom siv hluav taws xob. Nws kuj tseem siv tau ua tus neeg sawv cev sib txuas lus nyob hauv kev tsim cov nplaum, txheej, thiab lwm yam khoom.
Hauv kev xaus,4,4'-oxydiphthhalic anhydrid li cas 1823-59-2yog ib qho kev sib txuam hauv nruab nrab uas muaj ntau cov kev thov tseem ceeb hauv ntau yam kev lag luam. Nws siv rau hauv kev tsim cov kev ua haujlwm siab polymers, cov hlua khi, nplaim taws retardants, thiab lwm yam khoom tau pab txhawb rau kev nce qib ntawm ntau cov tswv yim. Vim nws cov khoom muaj txiaj ntsig thiab cov ntawv thov sib txuam ntau yam, ODPA yog qhov tseem ceeb tshaj plaws hauv kev txhim kho yav tom ntej ntawm kev lag luam yav tom ntej ntawm ntau yam kev lag luam.
