Acrylate ikoreshwa cyane mugukora ibikoresho bitandukanye bya polymer kubera ubushyuhe bwayo buke, kurwanya ubushyuhe, kurwanya gusaza, gukorera mu mucyo no guhagarara neza.Iyi mitungo ituma ishobora gukoreshwa muburyo butandukanye bwa porogaramu, harimo plastiki, langi zo hasi, impuzu, imyenda, amarangi hamwe n’ibiti.Ubwoko nubunini bwa acrylate monomers ikoreshwa bigira ingaruka zikomeye kumikorere yibicuruzwa byanyuma, harimo ubushyuhe bwikirahure, ubukonje, ubukomere nigihe kirekire.Polimeri nyinshi zibereye porogaramu zitandukanye zirashobora kuboneka hamwe na cololymerisation hamwe na monomers hamwe na hydroxyl, methyl cyangwa carboxyl matsinda akora.
Ibikoresho byabonetse na polymerisation ya acrylate monomers bikoreshwa cyane munganda, ariko monomer zisigaye zikunze kuboneka mubikoresho bya polymeric.Izi monomer zisigaye ntizishobora gusa gutera uburibwe bwuruhu nibindi bibazo, ahubwo zishobora no guteza impumuro mbi mubicuruzwa byanyuma kubera umunuko udashimishije waba monomers.
Sisitemu ya olfactory yumubiri wumuntu irashobora kumva acrylate monomer yibanda cyane.Kubikoresho byinshi bya acrylate polymer, impumuro yibicuruzwa ahanini biva muri acrylate monomers.Monomers zitandukanye zifite impumuro zitandukanye, ariko ni irihe sano riri hagati yimiterere ya monomer numunuko?Patrick Bauer wo muri Friedrich Alexander Universit ä t erlangen-n ü rnberg (Fau) mu Budage yize ubwoko bwimpumuro numubare wimpumuro yuruhererekane rwubucuruzi bwa acrylate monomers.
Muri rusange ubu bushakashatsi bwakozwe na monomers 20.Aba monomers barimo ubucuruzi na laboratoire.Ikizamini cyerekana ko umunuko w'aba monomers ushobora kugabanywamo sulfure, gaze yoroshye, geranium n'ibihumyo.
Diacrylate 1,2-propanediol (No 16), methyl acrylate (No 1), Ethyl acrylate (No 2) na propyl acrylate (No 3) basobanurwa cyane nkimpumuro ya sulfure na tungurusumu.Byongeye kandi, ibintu bibiri byanyuma bisobanurwa kandi ko bifite impumuro nziza ya gaze, mugihe Ethyl acrylate na 1,2-propylene glycol diacrylate ifite impumuro nziza ya kole.Vinyl acrylate (No 5) na propenyl acrylate (No 6) bisobanurwa nkimpumuro ya lisansi ya gaze, mugihe 1-hydroxyisopropyl acrylate (No 10) na acrylate 2-hydroxypropyl (No 12) isobanurwa nka geranium nimpumuro nziza ya gaze. .N-butyl acrylate (No 4), 3- (z) pentene acrylate (No 7), SEC butyl acrylate (geranium, uburyohe bwibihumyo; No 8), 2-hydroxyethyl acrylate (No 11), 4-methylamyl acrylate (ibihumyo, uburyohe bwimbuto; No 14) na Ethylene glycol diacrylate (No 15) bisobanurwa nkuburyohe bwibihumyo.Isobutyl acrylate (No 9), 2-Ethylhexyl acrylate (No 13), cyclopentanyl acrylate (No 17) na cyclohexane acrylate (No 18) bisobanurwa nkimpumuro ya karoti na Geranium.2-mikorerexyphenyl acrylate (No 19) numunuko wa geranium hamwe na ham yanyweye, mugihe isomer yayo 4-mitoxyphenyl acrylate (No 20) isobanurwa nkimpumuro ya anise na fennel.
Impumuro ntarengwa ya monomers yapimwe yerekanye itandukaniro rikomeye.Hano, urwego rwumunuko rwerekeza ku kwibumbira hamwe kwibintu bitanga imbaraga nkeya kubitekerezo byimpumuro yabantu, bizwi kandi ko ari impumuro nziza.Iyo hejuru yumunuko urenze, niko umunuko ugabanuka.Birashobora kugaragara mubisubizo byubushakashatsi ko impumuro yimpumuro yibasiwe nitsinda ryimikorere kuruta uburebure bwurunigi.Muri monomers 20 zapimwe, 2-mikorerexyphenyl acrylate (No 19) na SEC butyl acrylate (No 8) yari ifite umunuko muto cyane, wari 0.068ng / lair na 0.073ng / lair.2-hydroxypropyl acrylate (No 12) na 2-hydroxyethyl acrylate (No 11) yerekanye impumuro nziza cyane, yari 106 ng / lair na 178 ng / lair, inshuro zirenga 5 na 9 za 2-Ethylhexyl acrylate (No 13).
Niba hari chiral centre muri molekile, imiterere ya chiral itandukanye nayo igira ingaruka kumunuko wa molekile.Ariko, nta nyigisho ihanganye kugeza ubu.Urunigi rwuruhande muri molekile narwo rufite uruhare runini kumunuko wa monomer, ariko haribisanzwe.
Methyl acrylate (No 1), Ethyl acrylate (No 2), propyl acrylate (No 3) hamwe nabandi ba monomor bigufi berekana impumuro imwe na sulfure na tungurusumu, ariko umunuko uzagenda ugabanuka buhoro buhoro hamwe no kongera uburebure bwurunigi.Iyo uburebure bwurunigi bwiyongereye, impumuro ya tungurusumu izagabanuka, kandi impumuro ya gaze yoroshye izabyara.Kwinjiza amatsinda ya hydroxyl mumurongo wuruhande bigira ingaruka kumikoranire ya intermolecular, kandi bizagira ingaruka zikomeye kumunuko wakira selile, bikavamo impumuro zitandukanye.Kuri ba monomers bafite vinyl cyangwa propenyl idahagije inshuro ebyiri, arizo vinyl acrylate (No 5) na propenyl acrylate (No 6), berekana gusa impumuro ya lisansi ya gaze.Muyandi magambo, kwinjiza kwa kabiri gufatishijwe kutuzuye guhambiriye kuganisha ku kubura impumuro ya sulfure cyangwa tungurusumu.
Iyo urunigi rwa karubone rwongerewe kuri atome ya karubone 4 cyangwa 5, impumuro igaragara izahinduka kuva sulfure na tungurusumu bihinduka ibihumyo na Geranium.Muri rusange, acrylate ya cyclopentanyl (No 17) na cyclohexane acrylate (No 18), ari monomers aliphatic, yerekana impumuro isa (impumuro ya geranium na karoti), kandi ziratandukanye gato.Kwinjiza iminyururu ya alifatique ntabwo bigira ingaruka zikomeye kumyumvire yumunuko.
