Cov khoom kuaj pom rau cov pib muaj xws li hom, seem seem, purity, stability, thiab polymer compatibility. Feem ntau siv cov txheej txheem kuaj pom muaj xws li roj chromatography, siab - ua kua chromatography, huab hwm coj spectrometry, spectrometry, thiab electrochemical txoj kev.
Gas chromatography-mass spectrometry (GC-MS) yog ib txoj hauv kev tseem ceeb rau kev txiav txim siab cov ntsiab lus pib, tsim nyog rau kev txiav txim siab cov ntsiab lus ntawm photoinitiators hauv hluav taws xob- kho coatings. Txoj kev no kuj tseem siv los txiav txim siab cuaj photoinitiators, suav nrog benzophenone thiab 4-methylbenzophenone, hauv cov khoom ntim khoom noj. Txoj kev tshawb nrhiav tau tsim los ntawm kev ua kom zoo dua cov qauv ua ntej kho thiab GC-MS nrhiav pom cov xwm txheej.
Initiator concentration titration yog ib kauj ruam tseem ceeb ntawm kev tswj kom zoo nyob rau hauv polymer synthesis thiab tshuaj ntau lawm. Cov ntsiab lus ntawm peroxide pib txiav txim siab siv iodometric titration lossis cerium sulfate titration, thaum azo pib concentration tsom xam raws li cov yam ntxwv decomposition ntawm diazo pawg.
Kev ntsuas kev ua tau zoo ntawm macromolecular photoinitiators suav nrog photoinitiated polymerization kinetics, ntsuas thermogravimetric, thiab kev ntsuas txheej txheem. Piv txwv li, qhov siab tshaj plaws cov tshuaj tiv thaiv ntawm PTF photoinitiator pib lub polymerization ntawm trimethylolpropane triacrylate yog 0.037 s⁻¹. Thermogravimetric tsom xam qhia tau hais tias nws thermal stability yog siab dua li ntawm 1173 photoinitiator. Kev ntsuam xyuas txheej txheem qhia tau hais tias cov txiaj ntsig zoo dua thaum tus nqi ntawm PTF yog 4% ntawm cov feem ntau ntawm cov txheej txheem kho.
