Yog tias tetramethoxymethyl glycoluril sawv cev rau qhov ua tiav ntawm "methyl-etherified" kev taw qhia hauv tsev neeg glycoluril, tom qab ntawd cov txheej txheem derivatization uas pib los ntawm nws qhib qhov chaw dav dua ntawm daim ntawv thov muaj peev xwm rau tsev neeg molecular no.
Lub classic hluavtaws txoj kev rau TMMGU yog raws li nram no: glycoluril yog thawj reacted nrog formaldehyde los tawm lub tetramethylol glycoluril intermediate, uas yog ces etherified nrog methanol rau thaum kawg tsim tetramethoxymethyl glycoluril resin. Tsim los ntawm qhov no, chemists nyob deb ntawm cov ntsiab lus nrog tsuas yog "methoxy" kev xaiv. Piv txwv li, cov ntaub ntawv patent tau tshaj tawm tias los ntawm kev sib cais tetramethoxymethyl glycoluril nyob rau hauv ntau tshaj propylene glycol methyl ether thiab catalyzing cov tshuaj tiv thaiv nrog ib tug cation txauv resin, ib tug muaj peev xwm npaj TMMGU derivatives nrog ntev ceg chains thiab loj molecular spatial conformations. Cov derivatives no nthuav tawm ntxiv kev txhim kho crosslinking lub zog thiab kev ruaj ntseg, tuav cov lus cog tseg rau cov ntawv thov hauv siab - kub thiab huab cua tsis zoo hmoov txheej rau cov haujlwm siab heev xws li cov cuab yeej siv dav hlau.
Raws li plaub lub nitrogen atoms ntawm glycoluril skeleton, chemists tuaj yeem hloov cov methoxy pawg nrog alkoxy chains ntawm qhov sib txawv, xws li ethoxy lossis butoxy pawg, yielding ib tug series ntawm derivatives xws li tetraethoxymethyl glycoluril thiab tetrabutoxymethyl glycoluril. Cov sab sib txawv- cov saw ntev sib txawv sib txawv solubilities, cov ntsiab lus melting, thiab crosslinking reactivities rau cov molecules, ua rau lawv ua tau raws li cov kev cai ntawm ntau hom resin systems thiab cov txheej txheem ua. Los ntawm "tetramethoxy" mus rau "tetrabutoxy," TMMGU tsis yog ib qho ci hlaws ntawm cov hmoov txheej crosslinkers, tab sis kuj yog ib qho tseem ceeb hub ua rau "molecular toolbox" ntawm glycoluril derivatives. Cov txheej txheem tunability thiab kev ua haujlwm tsim nyog tom qab nws tau txuas ntxiv qhov tseem ceeb hauv kev lag luam coatings, cov khoom siv hluav taws xob, thiab cov khoom siv tshuaj tshwj xeeb.
