4 cyano 4 dodecylsulfanylthiocarbonyl pentanoic acid cdp

The monomers 2-(dimethylamino)ethyl methacrylate (DMAEMA, 98%) and (oligo ethylene glycol)methacrylate (OEGMA) (average Mn = 950 g∙mol⁻¹, 19 ethylene oxide units) were purchased from Sigma Aldrich, Greece. Both DMAEMA and OEGMA were purified using a column filled with inhibitor removers before polymerization. 2,2′-Azobis (isobutyronitrile) (AIBN), the radical initiator utilized, was purified by recrystallization from methanol. 4-Cyano-4-(dodecylsulfanylthiocarbonyl)pentanoic acid (CDP) as the CTA, methyl iodide (CH₃I) 1-iodohexane (C₆H₁₃I, ≥98%), 1-iodododecane (C₁₂H₂₅I, 98%), 1,4-dioxane (≥99.8% pure), and tetrahydrofuran (THF, ≥99.9% pure) were obtained from Sigma Aldrich, Greece and used as received, except 1-4-dioxane, which was first dried over molecular sieves. Deuterated chloroform (CDCl₃) was used as the solvent for the ¹H-NMR experiments and was also obtained from Sigma Aldrich, Greece. Dialysis tubing membranes (MEMBRA-CEL^®) from regenerated cellulose of MWCO 3500 and a diameter of 22 mm were purchased from SERVA, Heidelberg, Germany.

Monomers 2-(dimethylamino)ethyl methacrylate (DMAEMA, 98%) and (oligo ethylene glycol)methacrylate (OEGMA) (average Mn = 950 g·mol⁻¹), purchased from Sigma Aldrich (Athens, Greece), were purified through a column filled with inhibitor removers 311340 and 311332 (Sigma Aldrich). 2,2′ -Azobis (isobutyronitrile) (AIBN), which was used as the radical initiator, was purified through recrystallization from methanol. 1,4-dioxane (99.8% pure), the solvent utilized for the reaction, was obtained from Sigma Aldrich and dried using molecular sieves. 4-Cyano-4-(dodecylsulfanylthiocarbonyl)pentanoic acid (CDP), as the CTA, methyl iodide (CH₃I), citric acid, ethylenediamine, tetrahydrofuran (THF, ≥99.9% pure), and deuterated chloroform (CDCl₃) were used as obtained from Sigma Aldrich (Greece). Dialysis tubing membranes (MEMBRA-CEL^®, Lombard, IL, USA) from regenerated cellulose of MWCO 3500 and a diameter of 22 mm were purchased from SERVA, Heidelberg, Germany.
