Lub luag haujlwm tseem ceeb dab tsi ua cov organic acids thiab anhydrides ua si rau polymers?
Kev siv cov kua qaub rau polymers
Acid tuaj yeem siv los ua cov khoom siv los txhawb cov polymerization, piv txwv li, hauv cov txheej txheem ntawm kev npaj polyester, kua qaub tuaj yeem ua kom cov tshuaj tiv thaiv esterification ntawm cawv thiab kua qaub.
Qee zaum, cov kua qaub kuj tuaj yeem ua rau lub nplhaib-qhib polymerization tshwm sim, xws li lub nplhaib-qhib polymerization ntawm cyclic monomers. Qee cov polymers tuaj yeem txhim kho lawv cov khoom siv dag zog thiab cov cua sov los ntawm cov kua qaub-catalyzed crosslinking cov tshuaj tiv thaiv.
Kev siv cov anhydride hauv polymers
Ntau cov anhydrides tuaj yeem siv los ua monomers los ua ke polymers. Piv txwv li, maleic anhydride tuaj yeem ua copolymerized nrog lwm cov monomers los tsim cov polymers nrog cov khoom tshwj xeeb, xws li cov copolymer siv hauv cov txheej thiab cov nplaum. Pyromellitic dianhydride tuaj yeem siv los ua monomer los ua ke polyimide. Anhydride kuj tseem tuaj yeem siv los ua tus neeg sawv cev sib txuas los txhim kho qhov sib txuas ntawm qhov ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom ntom polymer Piv txwv li, pyeomellitic dianhydride (PMDA) thiab phthalic anhydride (PA) tuaj yeem siv los ua tus neeg sawv cev sib txuas rau epoxy resins. Anhydride tuaj yeem siv los ua cov khoom siv polymer nrog cov haujlwm tshwj xeeb thiab siv, xws li roj hmab, yas, thiab lwm yam.

Polyimide Monomer -Pyromellitic dianhydride (PMDA) & 4,4'-Oxydaniline (ODA)
Polyimide (PI) yog ib chav kawm ntawm cov polymers uas muaj kev ua tau zoo nrog thermal stability, tshuaj stability thiab txhua yam khoom. Lawv feem ntau muaj ib chav tsev ntawm preimine monomer nrog ob pawg acyl thiab tuaj yeem ua cov thermoset lossis thermoplastic. Polyimide yog dav siv nyob rau hauv ntau lub teb vim nws cov khoom zoo heev ntawm qhov kub thiab txias.
Yuav ua li cas npaj cov yeeb yaj kiab polyimide nrog PMDA thiab 4,4'-diaminodiphenyl ether (ODA)? .
Pyromellitic dianhydride (PMDA) thiab 4,4 '-diaminodiphenyl ether (ODA) yog cov ntaub ntawv tseem ceeb rau kev npaj cov yeeb yaj kiab polyimide ua haujlwm siab. Ua ntej, ODA yog yaj hauv cov kuab tshuaj uas tsim nyog, xws li N, N-dimethylacetamide (DMAC), thiab tom qab ntawd PMDA ntxiv rau hauv kev tiv thaiv nitrogen, tswj cov tshuaj tiv thaiv kub ntawm 0 thiab 20 degree los tsim cov tshuaj polyamide tuab. Tom ntej no, cov kev daws teeb meem yog dov mus rau hauv cov hlau sawb los ntawm cov txheej txheem casting los ua ib lub gel, uas tom qab ntawd qhuav los ntawm qhov kub thiab txias gradient kom tshem tawm cov kuab tshuaj thiab tsim ib zaj duab xis nrog qee qhov kev txhawb nqa tus kheej. Thaum kawg, ntawm qhov kub thiab txias (feem ntau tshaj 200 degree), imide yog ua, piv txwv li lub cev qhuav dej kaw lub voj los ua ib zaj duab xis polyimide. Raws li qhov xav tau, cov yeeb yaj kiab kuj tseem tuaj yeem ncab los txhim kho nws cov khoom siv kho tshuab, thiab txias, txiav thiab ntim. Vim nws zoo heev thermal stability thiab tshuaj stability, zaj duab xis no tau dav siv nyob rau hauv aerospace, microelectronics, optical fiber kev sib txuas lus thiab lwm yam teb.
