Kwinjiza itsinda rya kabiri rya acrylate, Ethylene glycol diacrylate (No 15), kuri 2-hydroxyethyl acrylate (No 11) ntabwo byazanye impinduka nyinshi mumunuko.Iyambere yerekana impumuro y'ibihumyo, mugihe iyanyuma yerekana impumuro y'ibihumyo na mususu.Nyamara, kuri diacrylate ya 1,2-propanediol (No 16) nyuma yo kwinjiza itsinda rya kabiri rya acrylate muri acide acrylic-1-hydroxyisopropyl ester (No 10) / Acide Acrylic-2-Hydroxypropyl ester (No 12) , impumuro ya geranium na lisansi yoroheje ya monoester yazimiye muri mazutu, kandi impumuro ya tungurusumu na kole yabyaye muri mazutu.
Muburyo bwose bugororotse n-alkyl acrylates, Ethyl acrylate (No 2) yerekanaga umunuko muto cyane, wari 0.83ng / lair.Hamwe no kwiyongera k'uburebure bw'urunigi, urwego rwiyongereyeho gato, na n-butyl acrylate (No 4) yageze kuri 2.4ng / lair.Nyamara, iri tegeko ntabwo buri gihe riba ingirakamaro, kubera ko inzitizi ya methyl acrylate (No 1) hamwe numurongo mugufi muri ba monomers bane ni hejuru (11 ng / lair).Ugereranije na acrylate monomers ihuye na Ethyl acrylate (No 2) na propyl acrylate (No 3), vinyl acrylate (No 5) na propenyl acrylate (No 6) irimo imigozi ibiri idahagije yerekanaga inshuro 20 na 3,5 munsi yumunuko muto. .Ibi byerekana ko kwinjiza imigozi ibiri idahagije mumurongo wa karubone bizongera cyane impumuro yumunuko kandi bigabanye imyumvire.Ariko, niba inkwano zidahagije zitari kumurongo wanyuma, ingaruka ntizigaragara.Kurugero, impumuro yumubare wa acrylic acide-3- (z) pentene ester (No 7) ni gusa (1.3 ng / lair).
Muri esters zose za alkyl acrylate, 2-Ethylhexyl acrylate (No 13) yerekanaga impumuro ndende ya 20ng / lair, ibyo bikaba byari bifitanye isano n’imikoranire idahwitse hagati ya 2-Ethylhexyl niyakira impumuro mbi kubera ingaruka zikomeye za 2-Ethylhexyl.Impumuro ndende ya acrilite ya 2-etylhexyl no kuyikoresha mugutezimbere ubworoherane nubworoherane bwa acrylic resin ikwirakwiza bituma ikwiriye gukoreshwa nkiyongera cyangwa comonomer muburyo buke bwo gutwika impumuro nziza.Nyamara, guhura igihe kirekire na 2-etylhexyl acrylate bishobora gutera ikibyimba cyangwa kanseri, kandi impumuro yacyo ndende ishobora guhinduka nabi, kuko itazabonwa numubiri wumuntu.
Impumuro ntarengwa ya acrylate irimo cyclopentane na cyclohexane (No 17 na 18) ntabwo iri munsi yubwa cycloalkyl ifite numero imwe ya atome ya karubone.Muri icyo gihe, impumuro y’imisemburo ya cyclopentane acrylate (No 17) yikubye inshuro 30 ugereranije na acrylate ya cyclohexane (No 18).
Kuri 2-hydroxyethyl acrylate (No 11) na 2-hydroxy-n-propyl acrylate (No 12), kwinjiza hydroxyl muri iyo miterere byateje imbere cyane impumuro yumunuko, wari 178 na 106ng / lair, ibyo bikaba byaragize ibyabo umunuko uri hasi cyane.Inzira imwe irashobora kugaragara uhereye kubitandukanya impumuro yumunani hagati ya sec butyl acrylate (No 8) na 1-hydroxyisopropyl acrylate (No 10).
Hamwe nogutangiza SEC butyl, impumuro yumunwa wa acrylate yagabanutse kuburyo bugera kuri 0.073ng / lair gusa, byerekana umunuko muto cyane muri alkyl acrylates zose, ni ukuvuga umunuko ukomeye.
Muri ba monomor 20 bagenwe, 2-mikorerexyphenyl acrylate (No 19) yerekanye umunuko muto cyane, wari 0.068ng / lair.Impumuro yumubare wa 2-mikorerexyphenyl ester, ikoreshwa cyane nkibintu byingenzi mubucuruzi bwibiribwa ninganda zikora uburyohe, ni 0.088ng / lair.Ibi byerekana ko esters ebyiri zifite 2-mikorerexyphenyl zifite uruhare mukwakira umunuko umwe.
Ubushakashatsi bwakozwe na Patrick Bauer hamwe n’abandi kuri monomers 20 ya acrylate bwerekanye ko monomers ngufi zigaragaza cyane cyane umunuko umeze nka sulfure, gaze yoroheje na tungurusumu, mu gihe monomers ndende zerekana cyane umunuko umeze nk'ibihumyo, geranium na karoti.Monomers zose za acrylate zerekanaga impumuro nke ugereranije, nukuvuga, bose bari bafite impumuro nini.Impumuro yumubare wa SEC butyl acrylate na 2-mikorerexyphenyl acrylate yari mike cyane, yerekana umunuko ukomeye.2-hydroxyethyl acrylate na 2-hydroxypropyl acrylate yari ifite umunuko mwinshi numunuko muto.
