cov xwm txheej cia khoom 2-8 ° C,

Tus coefficient ntawm acidity (pKa) 8.21 ± 0.28 (Kwv yees),

lub xeev kua pob tshab, tsis muaj xim rau daj ntseg rau daj ntseg txiv kab ntxwv.

Daim Ntawv Thov: Hauv txoj kev tshawb fawb no, dimethylaminoethyl acrylate tau siv los ua cov kuab tshuaj los tshawb nrhiav qhov hydrolytic stability ntawm poly (2-dimethylamino) methacrylate, uas tau piv rau ntawm monomethylaminomethyl acrylate. Qhov tshwm sim no tau muab rau kev sib koom tes ntawm protonated dimethylamino pawg thiab carbonyl pawg, ua rau cov ester yooj yim dua rau kev tawm tsam nucleophilic los ntawm hydroxyl ion.
