Kuyamba kwa gulu lachiwiri la acrylate, ethylene glycol diacrylate (No. 15), ku 2-hydroxyethyl acrylate (No. 11) sikunabweretse kusintha kwakukulu kwa fungo.Yoyamba imasonyeza fungo la bowa, pamene yotsirizira imasonyeza fungo la bowa ndi moss.Komabe, chifukwa cha 1,2-propanediol diacrylate (No. 16) pambuyo pa kukhazikitsidwa kwa gulu lachiwiri la acrylate mu acrylic acid-1-hydroxyisopropyl ester (No. 10) / acrylic Acid-2-Hydroxypropyl ester (No. 12) , fungo la geranium ndi gasi lopepuka la monoester linazimiririka mu diester, ndipo fungo la adyo ndi guluu linapangidwa mu diester.
Pakati pa maunyolo onse owongoka n-alkyl acrylates, ethyl acrylate (No. 2) adawonetsa fungo lotsika kwambiri, lomwe linali 0.83ng / lair yokha.Ndi kuwonjezeka kwa unyolo kutalika, pakhomo linakula pang'ono, ndipo n-butyl acrylate (No. 4) inafika ku 2.4ng / lair.Komabe, lamuloli siligwira ntchito nthawi zonse, chifukwa pakhomo la methyl acrylate (No. 1) ndi unyolo wamfupi kwambiri pakati pa ma monomers anayi ndi apamwamba kwambiri (11 ng / lair).Poyerekeza ndi lolingana awo ano zimalimbikitsa acrylate monomers ethyl acrylate (No. 2) ndi propyl acrylate (No. 3), vinilu acrylate (No. 5) ndi propenyl acrylate (No. 6) munali unsaturated zomangira wapawiri anasonyeza 20 ndi 3.5 nthawi m'munsi fungo zipsera. .Izi zikuwonetsa kuti kukhazikitsidwa kwa zomangira ziwiri zopanda unsaturated mu unyolo wa kaboni kudzakulitsa kwambiri fungo la fungo ndikuchepetsa malingaliro a fungo.Komabe, ngati chomangira chapawiri chopanda unsaturated sichili pagulu la terminal, zotsatira zake sizodziwikiratu.Mwachitsanzo, phokoso la fungo la acrylic acid-3- (z) pentene ester (No. 7) ndi (1.3 ng / lair).
Pakati pa ma alkyl acrylate esters, 2-ethylhexyl acrylate (No. 13) inasonyeza fungo lapamwamba kwambiri la 20ng / lair, lomwe linali logwirizana ndi kuyanjana kofooka pakati pa 2-ethylhexyl ndi kuvomereza fungo chifukwa cha steric cholepheretsa zotsatira za 2-ethylhexyl.Kuchuluka kwa fungo la 2-ethylhexyl acrylate ndikugwiritsa ntchito kwake kuwongolera kufewa ndi kusinthasintha kwa acrylic resin dispersion kumapangitsa kuti ikhale yoyenera kugwiritsidwa ntchito ngati chowonjezera kapena comonomer mu zokutira zotsika fungo ndi zomatira.Komabe, kukhudzana kwa nthawi yayitali ndi 2-ethylhexyl acrylate kungayambitse chotupa kapena khansa, ndipo fungo lake lalitali likhoza kukhala lopanda pake, chifukwa silingawonekere ndi thupi la munthu.
Fungo la fungo la acrylate lomwe lili ndi cyclopentane ndi cyclohexane (No. 17 ndi 18) silotsika kuposa la non cycloalkyl ndi chiwerengero chofanana cha maatomu a carbon.Panthawi imodzimodziyo, phokoso la fungo la cyclopentane acrylate (No. 17) linali la 30 kuposa la cyclohexane acrylate (No. 18).
Kwa 2-hydroxyethyl acrylate (No. 11) ndi 2-hydroxy-n-propyl acrylate (No. 12), kukhazikitsidwa kwa hydroxyl mu kapangidwe kake kunathandizira kwambiri fungo la fungo, lomwe linali 178 ndi 106ng / lair, zomwe zinapangitsa fungo lotsika kwambiri.Mchitidwe womwewo ukhoza kuwonedwa kuchokera ku kusiyana kwa fungo la fungo pakati pa sec butyl acrylate (No. 8) ndi 1-hydroxyisopropyl acrylate (No. 10).
Ndi kukhazikitsidwa kwa SEC butyl, fungo la fungo la acrylate linachepetsedwa kwambiri kukhala 0.073ng / lair, kusonyeza fungo lotsika kwambiri pakati pa ma alkyl acrylates, ndiko kuti, fungo lamphamvu kwambiri.
Pakati pa ma monomers a 20 omwe adatsimikiza, 2-methoxyphenyl acrylate (No. 19) adawonetsa fungo lotsika kwambiri, lomwe linali 0.068ng / lair yokha.Kununkhira kwa 2-methoxyphenyl ester, komwe kumagwiritsidwa ntchito kwambiri ngati gwero lazakudya ndi mafakitale onunkhira, ndi 0.088ng/lair.Izi zikuwonetsa kuti ma esters awiri okhala ndi 2-methoxyphenyl kapangidwe kake amagwira nawo ntchito yovomereza fungo lomwelo.
Patrick Bauer ndi kafukufuku ena pa 20 acrylate monomers anasonyeza kuti yochepa unyolo monomers makamaka anasonyeza fungo lofanana sulfure, mpweya wopepuka ndi adyo, pamene monomers wautali unyolo makamaka anasonyeza fungo lofanana ndi bowa, geraniums ndi kaloti.Ma acrylate monomers onse adawonetsa fungo lotsika, ndiye kuti, onse anali ndi fungo lalikulu.Kununkhira kwa SEC butyl acrylate ndi 2-methoxyphenyl acrylate kunali kochepa kwambiri, kusonyeza fungo lamphamvu kwambiri.2-hydroxyethyl acrylate ndi 2-hydroxypropyl acrylate anali ndi fungo lapamwamba kwambiri komanso fungo lotsika kwambiri.
