Soo bandhigida kooxda labaad ee acrylate, ethylene glycol diacrylate (No. 15), ilaa 2-hydroxyethyl acrylate (No. 11) wax badan uma keenin ur.Midka hore wuxuu muujinayaa urta likaha, halka kan dambe uu muujinayo urta likaha iyo mooska.Si kastaba ha ahaatee, loogu talagalay 1,2-propanediol diacrylate (No. 16) ka dib markii la soo bandhigay kooxda labaad ee acrylate ee acrylic acid-1-hydroxyisopropyl ester (No. 10) / acrylic Acid-2-Hydroxypropyl ester (No. 12) , Geranium iyo ur gaas fudud oo monoester ah ayaa ka dhex lumay naaftada, waxaana ka soo baxay urta toonta iyo xabagta.
Dhammaan silsiladaha tooska ah ee n-alkyl acrylates, ethyl acrylate (No. 2) ayaa muujisay heerka urka ugu hooseeya, kaas oo ahaa 0.83ng/lair oo keliya.Kordhinta dhererka silsiladda, marinka ayaa kordhay wax yar, iyo n-butyl acrylate (No. 4) ayaa gaadhay 2.4ng/lair.Si kastaba ha ahaatee, xeerkani had iyo jeer ma aha mid waxtar leh, sababtoo ah marinka methyl acrylate (No. 1) oo leh silsiladda ugu gaaban ee afarta monomers ayaa ah kan ugu sarreeya (11 ng / lair).Marka la barbardhigo kuwa u dhigma ee acrylate monomers ethyl acrylate (No. 2) iyo propyl acrylate (No. 3), vinyl acrylate (No. 5) iyo propenyl acrylate (No. 6) oo ay ku jiraan bonds double unnsaturated waxay muujiyeen 20 iyo 3.5 jeer hoose ee ur urta. .Tani waxay muujinaysaa in soo bandhigida curaarta labajibbaaran ee silsiladda kaarboonku ay si weyn u kordhin doonto heerka urta waxayna yaraynaysaa aragtida urta.Si kastaba ha noqotee, haddii dammaanadda labajibbaaran ee aan la isku haynin aysan ku jirin kooxda terminalka, saameyntu ma muuqato.Tusaale ahaan, marinka urta acrylic acid-3- (z) pentene ester (No. 7) waa kaliya (1.3 ng/lair).
Dhammaan esters alkyl acrylate, 2-ethylhexyl acrylate (No. 13) ayaa muujisay heerka ugu sarreeya ee urta 20ng / lair, taas oo la xiriirta isdhexgalka daciifka ah ee u dhexeeya 2-ethylhexyl iyo ur aqbalaha sababtoo ah saameynta xannibaadda ee 2-ethylhexyl.Meesha sare ee urta 2-ethylhexyl acrylate iyo adeegsigeeda si loo hagaajiyo jilicsanaanta iyo dabacsanaanta kala firdhinta resin acrylic waxay ka dhigaysaa mid ku habboon in loo isticmaalo sida wax lagu daro ama comomer ah ee dahaarka ur yar iyo dhejisyada.Si kastaba ha ahaatee, xidhiidhka muddada-dheer ee 2-ethylhexyl acrylate waxay u horseedi kartaa buro ama kansar, heerkeeda urta sare waxay noqon kartaa khasaare, sababtoo ah ma ogaan doono jidhka bini'aadamka.
Meesha urta ee acrylate ka kooban cyclopentane iyo cyclohexane (No. 17 iyo 18) kama hooseeyo kan aan cycloalkyl oo leh isla tirada atamka kaarboonka.Isla mar ahaantaana, xadka urta ee cyclopentane acrylate (No. 17) wuxuu ahaa 30 jeer ka sarreeya kan cyclohexane acrylate (No. 18).
Wixii 2-hydroxyethyl acrylate (No. 11) iyo 2-hydroxy-n-propyl acrylate (No. 12), hordhaca ah ee hydroxyl ee qaab-dhismeedka ayaa si weyn u hagaajiyay marinka urta, kaas oo ahaa 178 iyo 106ng / lair siday u kala horreeyaan ur aad u hooseeya.Isbeddel la mid ah ayaa laga arki karaa farqiga urta urta u dhaxaysa sek butyl acrylate (No. 8) iyo 1-hydroxyisopropyl acrylate (No. 10).
Markii la soo bandhigay SEC butyl, heerka urta acrylate ayaa si weyn hoos loogu dhigay oo kaliya 0.073ng/lair, taasoo muujineysa heerka ugu hooseeya ee urta dhammaan acrylates alkyl, taas oo ah, urta ugu xoogga badan.
Waxaa ka mid ah 20-ka monomers ee la go'aamiyay, 2-methoxyphenyl acrylate (No. 19) waxay muujisay heerka urka ugu hooseeya, kaas oo ahaa 0.068ng/lair kaliya.Meesha urta ee 2-methoxyphenyl ester, oo si weyn loogu isticmaalo nuxur ahaan warshadaha cuntada iyo warshadaha dhadhanka, waa 0.088ng/lair.Tani waxay muujinaysaa in labada ester ee leh qaabdhismeedka 2-methoxyphenyl ay door ka ciyaaraan ur isku mid ah.
Patrick Bauer iyo cilmi-baaris kale oo ay ku sameeyeen 20-kan acrylate monomers ayaa muujiyay in monomers-yada gaaban ay inta badan soo bandhigaan ur la mid ah baaruud, gaas fudud iyo toon, halka monomers silsiladaha dheer ay inta badan soo bandhigaan ur la mid ah boqoshaada, geraniums iyo karootada.Dhammaan monomer-yada acrylate waxay muujiyeen marin urka aad u hooseeya, taas oo macnaheedu yahay, dhammaantood waxay lahaayeen ur weyn.Meesha urta ee SEC butyl acrylate iyo 2-methoxyphenyl acrylate ayaa si gaar ah u hooseeya, oo muujinaya urta ugu xoogga badan.2-hydroxyethyl acrylate iyo 2-hydroxypropyl acrylate ayaa lahaa marinka urka ugu sarreeya iyo urta ugu hooseysa.
