On February 28, 2021, Okten Besli, Nur Sena; Orakdogen, Nermin published an article.Synthetic Route of 2358-84-1 The title of the article was Design of weakly cationic alco-cryogels consisting of poly(alkylmethacrylates)-based sulfonated terpolymer network with tunable multiresponsive assembly. And the article contained the following:
Cryogels with ion-, and solvent-responsiveness have been designed by cryogelation of 2-(diethylamino)ethyl methacrylate (DEAEMA) as weakly cationic monomer, hydroxyethyl methacrylate as neutral comonomer and 2-acrylamido-2-methyl-1-propanesulfonic acid as anionic termonomer in ethanol-water mixture (50:50 volume/volume), which had been proved to offer a good miscibility of monomers. Influence of composition of terpolymer and polymerization temperature on the properties of terpolymer cryogels (Cgels) and hydrogels (Hgels) were evaluated by swelling kinetics, and response against rapid ionic strength change. Swelling of terpolymer networks in the form of Cgel and Hgel decreased with increase in the size of ions present in swelling medium and followed the order of swelling behavior Cl- > Br- > I-. Terpolymer alcogels exhibited salting-out behavior in the presence of Cl- and Br- ions, while “salting-in” behavior was observed in KI solutions of high concentrations Sensitivity sequence of terpolymer alcogels to mono- and di-valent cations with a common anion (SO42-) on swelling was Na+ > K+ > Mg2+> Zn2+. Swelling data agree well with second-order kinetic model and with increasing amount of DEAEMA in terpolymer feed, diffusion mechanism changed from non-Fickian type to Fickian diffusion. In ionic environments, the salt-sensitivity and excellent water absorption/retention capability give this intelligentized terpolymer gels wide potential applications. The experimental process involved the reaction of Oxybis(ethane-2,1-diyl) bis(2-methylacrylate)(cas: 2358-84-1).Synthetic Route of 2358-84-1
