Kev taw qhia ntawm pawg thib ob acrylate, ethylene glycol diacrylate (No. 15), mus rau 2-hydroxyethyl acrylate (No. 11) tsis coj ntau yam kev hloov hauv tsw.Lub qub qhia tau hais tias tsis hnov tsw ntawm nceb, thaum lub tom kawg qhia tau hais tias tsis hnov tsw ntawm nceb thiab moss.Txawm li cas los xij, rau 1,2-propanediol diacrylate (No. 16) tom qab kev taw qhia ntawm pawg thib ob acrylate hauv acrylic acid-1-hydroxyisopropyl ester (No. 10) / acrylic Acid-2-Hydroxypropyl ester (No. 12) , lub geranium thiab sib zog roj tsw ntawm lub monoester ploj nyob rau hauv lub diester, thiab cov ntxhiab tsw ntawm qej thiab kua nplaum yog generated nyob rau hauv lub diester.
Ntawm tag nrho cov saw ncaj n-alkyl acrylates, ethyl acrylate (No. 2) tau pom qhov qis qis tshaj plaws, uas tsuas yog 0.83ng / lair.Nrog rau qhov nce ntawm cov saw ntev, qhov pib nce me ntsis, thiab n-butyl acrylate (No. 4) mus txog 2.4ng / lair.Txawm li cas los xij, txoj cai no tsis yog ib txwm siv tau, vim tias qhov pib ntawm methyl acrylate (No. 1) nrog cov saw luv tshaj plaws ntawm plaub lub monomers yog qhov siab tshaj (11 ng / lair).Piv nrog rau lawv cov sib xws saturated acrylate monomers ethyl acrylate (No. 2) thiab propyl acrylate (No. 3), vinyl acrylate (No. 5) thiab propenyl acrylate (No. 6) uas muaj unsaturated ob daim ntawv cog lus pom 20 thiab 3.5 lub sij hawm txo qis dua. .Qhov no qhia tau hais tias qhov kev taw qhia ntawm unsaturated ob daim ntawv cog lus nyob rau hauv cov pa roj carbon saw yuav ua rau kom cov ntxhiab tsw pib thiab txo cov ntxhiab tsw.Txawm li cas los xij, yog tias qhov tsis txaus siab ob daim ntawv cog lus tsis nyob ntawm pawg davhlau ya nyob twg, cov txiaj ntsig tsis pom tseeb.Piv txwv li, cov ntxhiab tsw ntawm acrylic acid-3- (z) pentene ester (No. 7) tsuas yog (1.3 ng / lair).
Ntawm tag nrho cov alkyl acrylate esters, 2-ethylhexyl acrylate (No. 13) tau pom cov ntxhiab tsw ntau tshaj plaws ntawm 20ng / lair, uas muaj feem xyuam rau kev sib cuam tshuam tsis muaj zog ntawm 2-ethylhexyl thiab tsw tau txais vim qhov cuam tshuam steric hindrance ntawm 2-ethylhexyl.Lub siab tsw zoo ntawm 2-ethylhexyl acrylate thiab nws siv los txhim kho softness thiab saj zawg zog ntawm acrylic resin dispersion ua rau nws haum rau siv raws li ib tug additive los yog comonomer nyob rau hauv tsawg tsw coatings thiab adhesives.Txawm li cas los xij, kev sib cuag mus ntev nrog 2-ethylhexyl acrylate tuaj yeem ua rau qog nqaij hlav lossis mob qog noj ntshav, thiab nws cov ntxhiab tsw siab yuav dhau los ua qhov tsis zoo, vim nws yuav tsis pom los ntawm tib neeg lub cev.
Cov ntxhiab tsw pib ntawm acrylate uas muaj cyclopentane thiab cyclohexane (No. 17 thiab 18) tsis qis dua li cov uas tsis yog cycloalkyl nrog tib cov pa roj carbon atoms.Nyob rau tib lub sijhawm, cov ntxhiab tsw ntawm cyclopentane acrylate (No. 17) yog 30 npaug siab dua li ntawm cyclohexane acrylate (No. 18).
Rau 2-hydroxyethyl acrylate (No. 11) thiab 2-hydroxy-n-propyl acrylate (No. 12), cov kev taw qhia ntawm hydroxyl nyob rau hauv cov qauv zoo heev txhim kho cov ntxhiab tsw, uas yog 178 thiab 106ng / lair feem, uas ua rau lawv. tsw qab heev.Tib qhov sib txawv tuaj yeem pom los ntawm qhov sib txawv ntawm cov ntxhiab tsw nruab nrab ntawm sec butyl acrylate (No. 8) thiab 1-hydroxyisopropyl acrylate (No. 10).
Nrog rau kev qhia txog SEC butyl, cov ntxhiab tsw pib ntawm acrylate tau txo qis rau tsuas yog 0.073ng / lair, uas qhia cov ntxhiab tsw qis tshaj plaws ntawm tag nrho cov alkyl acrylates, uas yog, tus ntxhiab tsw tshaj plaws.
Ntawm 20 monomers tau txiav txim siab, 2-methoxyphenyl acrylate (No. 19) tau pom cov ntxhiab tsw qis tshaj plaws, uas tsuas yog 0.068ng / lair.Cov ntxhiab tsw ntawm 2-methoxyphenyl ester, uas yog dav siv los ua cov ntsiab lus hauv kev lag luam zaub mov thiab kev lag luam tsw, yog 0.088ng / lair.Qhov no qhia tau hais tias ob lub esters nrog 2-methoxyphenyl qauv ua lub luag haujlwm hauv tib tus ntxhiab tsw.
Patrick Bauer thiab lwm tus 'kev tshawb fawb ntawm 20 acrylate monomers pom tias cov saw luv luv monomers tsuas yog tso tawm cov ntxhiab tsw zoo ib yam li sulfur, sib dua roj thiab qej, thaum cov saw ntev monomers feem ntau pom cov ntxhiab tsw zoo ib yam li nceb, geraniums thiab carrots.Tag nrho cov acrylate monomers pom cov ntxhiab tsw qis, uas yog hais tias, lawv txhua tus muaj ntxhiab tsw loj.Cov ntxhiab tsw ntawm SEC butyl acrylate thiab 2-methoxyphenyl acrylate tshwj xeeb yog qis, uas qhia cov ntxhiab tsw zoo tshaj plaws.2-hydroxyethyl acrylate thiab 2-hydroxypropyl acrylate muaj cov ntxhiab tsw tshaj plaws thiab cov ntxhiab tsw qab tshaj plaws.
