ʻO ka hoʻokomoʻana i ka hui acrylateʻelua, ethylene glycol diacrylate (No. 15), i ka 2-hydroxyethyl acrylate (No. 11)ʻaʻole i lawe mai i ka loli nui i kaʻala.Hōʻike ka mua i ke ʻala o ka halo, a ʻo ka mea hope e hōʻike i ke ʻala o ka halo a me ka moss.Eia naʻe, no ka 1,2-propanediol diacrylate (No. 16) ma hope o ka hoʻokomo ʻana o ka lua acrylate pūʻulu i ka acrylic acid-1-hydroxyisopropyl ester (No. 10) / acrylic Acid-2-Hydroxypropyl ester (No. 12) , ua nalowale ka ʻala geranium a me ka māmā o ka monoester i ka diester, a ua hana ʻia ke ʻala o ke kālika a me ke kāpili i ka diester.
Ma waena o nā kaulahao pololei n-alkyl acrylates, ethyl acrylate (No. 2) i hōʻike i ka paepae ʻala haʻahaʻa, ʻo ia wale nō ka 0.83ng/lair.Me ka piʻi ʻana o ka lōʻihi o ke kaulahao, ua piʻi iki ka paepae, a hiki i ka n-butyl acrylate (No. 4) i 2.4ng / lair.Eia naʻe, ʻaʻole maikaʻi kēia lula, no ka mea, ʻo ka paepae o ka methyl acrylate (No. 1) me ke kaulahao pōkole loa ma waena o nā monomers ʻehā ka mea kiʻekiʻe loa (11 ng/lair).Hoʻohālikelike ʻia me kā lākou monomers saturated acrylate ethyl acrylate (No. 2) a me propyl acrylate (No. 3), vinyl acrylate (No. 5) a me propenyl acrylate (No. 6) i loaʻa nā paʻa pālua unsaturated i hōʻike ʻia he 20 a me 3.5 mau manawa haʻahaʻa haʻahaʻa paepae ʻala. .Hōʻike kēia i ka hoʻokomo ʻana i nā paʻa pālua unsaturated i loko o ke kaulahao kalapona e hoʻonui nui i ka paepae ʻala a hōʻemi i ka ʻike ʻala.Eia nō naʻe, inā ʻaʻole ka paʻa pālua unsaturated ma ka pūʻulu hoʻopau, ʻaʻole maopopo ka hopena.No ka laʻana, ʻo ka paepae ʻala o ka acrylic acid-3- (z) pentene ester (No. 7) he (1.3 ng/lair wale nō).
Ma waena o nā esters alkyl acrylate a pau, ua hōʻike ʻo 2-ethylhexyl acrylate (No. 13) i ka paepae ʻala kiʻekiʻe loa o 20ng/lair, i pili i ka pilina nāwaliwali ma waena o 2-ethylhexyl a me ka mea ʻala ma muli o ka hopena steric hindrance o 2-ethylhexyl.ʻO ka paepae ʻala kiʻekiʻe o 2-ethylhexyl acrylate a me kona hoʻohana ʻana e hoʻomaikaʻi i ka palupalu a me ka maʻalahi o ka dispersion resin acrylic e kūpono ia no ka hoʻohana ʻana ma ke ʻano he additive a i ʻole comonomer i nā uhi haʻahaʻa a me nā mea hoʻopili.Eia naʻe, hiki i ka pilina lōʻihi me 2-ethylhexyl acrylate ke alakaʻi i ka maʻi ʻaʻai a i ʻole ka maʻi kanesa, a lilo paha kona paepae ʻala kiʻekiʻe i mea pōʻino, no ka mea, ʻaʻole e ʻike ʻia e ke kino kanaka.
ʻAʻole emi ka paepae ʻala o ka acrylate me ka cyclopentane a me ka cyclohexane (No. 17 a me 18) ma mua o ka cycloalkyl ʻole me ka helu like o nā mana kalapona.Ma ka manawa like, ʻo ka paepae ʻala o ka cyclopentane acrylate (No. 17) he 30 mau manawa kiʻekiʻe ma mua o ka cyclohexane acrylate (No. 18).
No ka 2-hydroxyethyl acrylate (No. 11) a me 2-hydroxy-n-propyl acrylate (No. 12), ka hoʻokomo ʻana o ka hydroxyl i loko o ka hale i hoʻomaikaʻi maikaʻi loa i ka paepae ʻala, ʻo ia ka 178 a me 106ng/lair, i hana i kā lākou. ʻala haʻahaʻa loa.Hiki ke ʻike ʻia ke ʻano like mai ka ʻokoʻa o ka paepae ʻala ma waena o kekona butyl acrylate (No. 8) a me 1-hydroxyisopropyl acrylate (No. 10).
Me ka hoʻokomo ʻana o SEC butyl, ua hoʻemi nui ʻia ka paepae ʻala o ka acrylate i ka 0.073ng/lair wale nō, e hōʻike ana i ka paepae ʻala haʻahaʻa ma waena o nā acrylates alkyl a pau, ʻo ia hoʻi ka ʻala ikaika loa.
Ma waena o nā monomers 20 i hoʻoholo ʻia, 2-methoxyphenyl acrylate (No. 19) i hōʻike i ka paepae ʻala haʻahaʻa, ʻo ia wale nō 0.068ng/lair.ʻO ka paepae ʻala o ka 2-methoxyphenyl ester, i hoʻohana nui ʻia e like me ke ʻano o ka ʻoihana meaʻai a me ka ʻoihana ʻono, ʻo 0.088ng / lair.Hōʻike kēia i nā esters ʻelua me ka hoʻolālā 2-methoxyphenyl e pāʻani i kahi hana i ka mea ʻae ʻala like.
ʻO ka noiʻi ʻana a Patrick Bauer a me nā mea ʻē aʻe no kēia mau monomers acrylate he 20, ua hōʻike nui ʻia nā monomers kaulahao pōkole i ka ʻala e like me ka sulfur, ke kinoea māmā a me ke kāleka, ʻoiai ʻo nā monomers kaulahao lōʻihi e hōʻike nui i ka ʻala e like me nā halo, geraniums a me kāloti.Hōʻike nā monomers acrylate a pau i ka paepae ʻala haʻahaʻa, ʻo ia hoʻi, he ʻala nui lākou a pau.He haʻahaʻa loa nā paepae ʻala o SEC butyl acrylate a me 2-methoxyphenyl acrylate, e hōʻike ana i ka ʻala ikaika loa.ʻO 2-hydroxyethyl acrylate a me 2-hydroxypropyl acrylate ka paepae ʻala kiʻekiʻe loa a me ka ʻala haʻahaʻa loa.
