Acrylate inoshandiswa zvakanyanya mukugadzirwa kwezvinhu zvakasiyana-siyana zvepolymer nekuda kwekudzika kwayo tembiricha kuchinjika, kupisa kupisa, kuramba kuchembera, kujeka kwepamusoro uye kugadzikana kwemavara.Zvinhu izvi zvinoita kuti zvishandiswe mumhando dzakasiyana-siyana dzekushandisa, kusanganisira mapurasitiki, mavarnish epasi, machira, machira, pendi uye zvinonamira.Rudzi uye huwandu hweacrylate monomers inoshandiswa ine mhedzisiro yakakura pakuita kwechigadzirwa chekupedzisira, kusanganisira tembiricha yegirazi, viscosity, kuoma uye kusimba.Mamwe mapolymer akakodzera mashandisirwo akasiyana anogona kuwanikwa necopolymerization nemamonomers ane hydroxyl, methyl kana carboxyl anoshanda mapoka.
Zvinhu zvakawanikwa nepolymerization yeacrylate monomers zvinoshandiswa zvakanyanya muindasitiri, asi zvakasara monomers zvinowanzo kuwanikwa mune polymeric zvinhu.Aya akasara monomers anogona kusangokonzera kutsamwa kweganda uye mamwe matambudziko, asi zvakare kukonzera kunhuhwirira kusingafadzi muchigadzirwa chekupedzisira nekuda kwekunhuhwirira kusingafadzi kweaya monomers.
Iyo olfactory system yemuviri wemunhu inogona kunzwa acrylate monomer mune yakaderera zvakanyanya.Kune akawanda acrylate polymer zvinhu, kunhuwa kwezvigadzirwa kunowanzobva kune acrylate monomers.Mamonomeri akasiyana ane kunhuhwirira kwakasiyana, asi chii chiri hukama pakati pemonomeri chimiro uye kunhuwa?Patrick Bauer anobva kuFriedrich Alexander Universit ä t erlangen-n ü rnberg (Fau) kuGermany akadzidza mhando dzekunhuhwirira uye zvikumbaridzo zvehwema zvakatevedzana zvekutengesa uye synthesized acrylate monomers.
Huwandu hwe20 monomers vakaedzwa muchidzidzo ichi.Aya monomers anosanganisira kutengeserana uye marabhoritari akagadzirwa.Muedzo unoratidza kuti hwema hwemamonomeri aya hunogona kukamurwa kuita sarufa, gasi rakareruka, geranium uye howa.
1,2-propanediol diacrylate (No. 16), methyl acrylate (No. 1), ethyl acrylate (No. 2) uye propyl acrylate (No. 3) inonyanya kurondedzerwa se sulfur uye garlic inonhuhwirira.Pamusoro pezvo, zvinhu zviviri izvi zvekupedzisira zvinotsanangurwa zvakare sekunhuhwirira kwegasi rakareruka, nepo ethyl acrylate uye 1,2-propylene glycol diacrylate ine fungidziro yekunhuhwirira kweglue.Vinyl acrylate (No. 5) uye propenyl acrylate (Nhamba. 6) inotsanangurwa semafuta emafuta anonhuhwirira, nepo 1-hydroxyisopropyl acrylate (No. 10) uye 2-hydroxypropyl acrylate (No. 12) inorondedzerwa se geranium uye kunhuhwirira kwegesi yakareruka. .N-butyl acrylate (No. 4), 3- (z) pentene acrylate (No. 7), SEC butyl acrylate (geranium, mushroom flavour; No. 8), 2-hydroxyethyl acrylate (No. 11), 4-methylamyl acrylate (mushroom, fruit flavour; No. 14) uye ethylene glycol diacrylate (No. 15) inorondedzerwa sehowa inonaka.Isobutyl acrylate (No. 9), 2-ethylhexyl acrylate (No. 13), cyclopentanyl acrylate (No. 17) uye cyclohexane acrylate (No. 18) inorondedzerwa semakaroti uye Geranium kunhuhwirira.2-methoxyphenyl acrylate (No. 19) ndiyo kunhuwa kwegeranium uye kusvuta ham, nepo isomer yayo 4-methoxyphenyl acrylate (No. 20) inotsanangurwa sekunhuhwirira kweanise uye fennel.
Iyo yekunhuwa zvikumbaridzo zveakaedzwa monomers yakaratidza misiyano mikuru.Pano, chikumbaridzo chekunhuwa chinoreva kusangana kwechinhu chinoburitsa kakurudziro kunhuwidza yemunhu, inozivikanwawo sechikumbaridzo chekunhuwa.Iyo yakakwirira yekunhuwa kwechikumbaridzo, iyo yakaderera kunhuwa.Inogona kuonekwa kubva pamigumisiro yekuedza kuti chikumbaridzo chekunhuwa chinonyanya kukanganiswa nemapoka anoshanda kupfuura nekureba kweketani.Pakati pe20 monomers yakaedzwa, 2-methoxyphenyl acrylate (No. 19) uye SEC butyl acrylate (No. 8) yakanga ine yakaderera kunhuhwirira chikumbaridzo, iyo yaiva 0.068ng / lair uye 0.073ng / lair, maererano.2-hydroxypropyl acrylate (No. 12) uye 2-hydroxyethyl acrylate (No. 11) yakaratidza kunhuhwirira kwepamusoro, iyo yaiva 106 ng / lair uye 178 ng / lair, maererano, kupfuura 5 uye 9 nguva ye2-ethylhexyl. acrylate (No. 13).
Kana paine chiral nzvimbo mumorekuru, akasiyana chiral zvimiro zvakare zvine chekuita pakunhuhwirira kwemorekuru.Nekudaro, hapana chidzidzo chekukwikwidza panguva ino.Iketani yepadivi mumorekuru inewo imwe pesvedzero pakunhuhwirira kwemonomeri, asi pane zvisizvo.
Methyl acrylate (No. 1), ethyl acrylate (No. 2), propyl acrylate (No. 3) uye mamwe mafupi maketani monomers anoratidza kunhuhwirira kwakafanana nesarufa negariki, asi kunhuwa kuchaderera zvishoma nezvishoma nekuwedzera kweketani urefu.Kana hurefu hweketani huchiwedzera, kunhuhwirira kwegariki kuchaderera, uye kumwe kunhuhwirira kwegasi kunogadzirwa.Kuiswa kwemapoka e-hydroxyl mucheni yeparutivi kune kukanganisa pakubatana kwe intermolecular, uye kuchava nemigumisiro yakawanda pakunhuhwirira kwekugamuchira masero, zvichiita kuti pave nekunzwa kwekunhuwa kwakasiyana.Kune monomers ane vinyl kana propenyl unsaturated kaviri zvisungo, kureva vinyl acrylate (No. 5) uye propenyl acrylate (No. 6), vanongoratidza chete kunhuwa gaseous mafuta.Mune mamwe mazwi, kuiswa kwechipiri capped unsaturated kaviri bond kunotungamirira mukunyangarika kwesarufa kana garlic kunhuhwirira.
Kana kabhoni cheni yawedzerwa kusvika 4 kana 5 maatomu ekabhoni, kunhuwa kunoonekwa kuchachinja kubva pasarufa negariki kuenda kuhowa uye Geranium.Pakati pese, cyclopentanyl acrylate (No. 17) uye cyclohexane acrylate (No. 18), iyo aliphatic monomers, inoratidza kunhuhwirira kwakafanana (geranium uye karoti kunhuwa), uye zvakasiyana zvishoma.Iko kuiswa kwealiphatic side chain haina simba guru pamanzwiro ekunhuwa.
