Kutanga kweboka rechipiri acrylate, ethylene glycol diacrylate (No. 15), ku2-hydroxyethyl acrylate (No. 11) haina kuunza kuchinja kukuru mukunhuhwirira.Iyo yekutanga inoratidza kunhuwa kwehowa, nepo iyo yekupedzisira inoratidza kunhuhwirira kwehowa uye moss.Zvisinei, nokuda kwe1,2-propanediol diacrylate (No. 16) mushure mekutangwa kweboka rechipiri acrylate mu acrylic acid-1-hydroxyisopropyl ester (No. 10) / acrylic Acid-2-Hydroxypropyl ester (No. 12) , geranium uye gasi rakareruka kunhuhwirira kwe monoester kwakanyangarika mudiester, uye kunhuhwirira kwegariki uye glue kwakagadzirwa mudiester.
Pakati pese ketani yakatwasuka n-alkyl acrylates, ethyl acrylate (No. 2) yakaratidza yakaderera kunhuhwirira chikumbaridzo, iyo yaingova 0.83ng/lair.Nekuwedzera kweketani kureba, chikumbaridzo chakawedzera zvishoma, uye n-butyl acrylate (No. 4) yakasvika 2.4ng / lair.Zvisinei, mutemo uyu hausi kushanda nguva dzose, nokuti chikumbaridzo che methyl acrylate (Nhamba.Zvichienzaniswa avo anowirirana saturated acrylate monomers ethyl acrylate (No. 2) uye propyl acrylate (No. 3), vinyl acrylate (No. 5) uye propenyl acrylate (No. 6) ine unsaturated kaviri zvisungo akaratidza 20 uye 3.5 nguva yakaderera kunhuwa zvikumbaridzo. .Izvi zvinoratidza kuti kuiswa kweunsaturated kaviri zvisungo muketani yekabhoni kuchawedzera zvakanyanya kunhuwa kwechikumbaridzo uye kuderedza kunhuhwirira kwekuona.Nekudaro, kana iyo unsaturated kaviri chisungo chisiri pane terminal boka, mhedzisiro yacho haisi pachena.Somuenzaniso, kunhuwa chikumbaridzo che acrylic acid-3- (z) pentene ester (No. 7) chete (1.3 ng / lair).
Pakati pese alkyl acrylate esters, 2-ethylhexyl acrylate (No. 13) yakaratidza kunhuhwirira kwepamusoro pe20ng / lair, iyo yakanga yakabatana nekubatana kusina simba pakati pe2-ethylhexyl uye kunhuhwirira kwekugamuchira nekuda kwesteric hindrance effect ye2-ethylhexyl.Iyo yakanyanya kunhuwa chikumbaridzo che2-ethylhexyl acrylate uye kushandiswa kwayo kuvandudza kupfava uye kuchinjika kwe acrylic resin dispersion inoita kuti ive yakakodzera kushandiswa sekuwedzera kana comonomer mune yakaderera kunhuhwirira coatings uye adhesives.Zvisinei, kushamwaridzana kwenguva refu ne2-ethylhexyl acrylate kunogona kutungamirira kune bundu kana kenza, uye kunhuhwirira kwayo kwepamusoro kunogona kuva kukanganisa, nokuti hazvizonzwisisiki nemuviri wemunhu.
Chikumbaridzo chekunhuwa kwe acrylate ine cyclopentane uye cyclohexane (Nhamba. 17 uye 18) haisi pasi pane iyo isiri cycloalkyl ine nhamba yakafanana yeatomu kabhoni.Panguva imwecheteyo, kunhuhwirira kwechikumbaridzo che cyclopentane acrylate (No. 17) kwaiva ne30 nguva yakakwirira kupfuura ye cyclohexane acrylate (No. 18).
Kune 2-hydroxyethyl acrylate (No. 11) uye 2-hydroxy-n-propyl acrylate (No. 12), kuiswa kwehydroxyl muhutano kwakagadziridza zvikuru kunhuhwirira kwekunhuhwirira, iyo yaiva 178 uye 106ng / lair maererano, iyo yakaita hwema hushoma.Nzira imwechete inogona kuonekwa kubva pakusiyana kwekunhuhwirira kwepakati pakati pe sec butyl acrylate (No. 8) uye 1-hydroxyisopropyl acrylate (No. 10).
Nekuiswa kweSEC butyl, chikumbaridzo chekunhuhwirira kweacrylate chakanyanya kuderedzwa kusvika ku 0.073ng / lair chete, kuratidza kunhuhwirira kwakaderera pakati pese alkyl acrylates, kureva, kunhuhwirira kwakasimba.
Pakati pe20 monomers yakatemwa, 2-methoxyphenyl acrylate (No. 19) yakaratidza yakaderera kunhuhwirira chikumbaridzo, iyo yaingova 0.068ng/lair.Iyo yekunhuwa chikumbaridzo che2-methoxyphenyl ester, iyo inoshandiswa zvakanyanya sechinhu muindasitiri yechikafu uye indasitiri yekuravira, ndeye 0.088ng/lair.Izvi zvinoratidza kuti maester maviri ane 2-methoxyphenyl chimiro anoita basa mune imwechete inonhuwa inobvuma.
Patrick Bauer nevamwe 'kutsvagurudza pamusoro peaya makumi maviri acrylate monomers yakaratidza kuti mapfupi cheni monomers ainyanya kuratidza kunhuhwirira kwakafanana nesarufa, gasi rakareruka uye gariki, ukuwo macheni marefu monomers ainyanya kuratidza kunhuwa kwakafanana nehowa, geraniums uye makarotsi.Ese ma acrylate monomers airatidza kunhuhwirira kwakaderera, kureva kuti, vese vaive nekunhuhwirira kukuru.Kunhuwa zvikumbaridzo zveSEC butyl acrylate uye 2-methoxyphenyl acrylate zvakanyanya kuderera, zvichiratidza kunhuhwirira kwakasimba.2-hydroxyethyl acrylate uye 2-hydroxypropyl acrylate yakanga ine yepamusoro-soro yekunhuwa uye kunhuhwirira kwakaderera.
