A PSaMA sodium salt solution
13% (Mw 350,000), PScMA partial isobutyl
ester (Mw 65,000 g·mol–1), polyethylene glycol (PEG) (Mw 200
g·mol–1, PEG 200; Mw 400 g·mol–1, PEG 400; Mw 600 g·mol–1, PEG 600; Mw 1500 g·mol–1, PEG 1500; Mw 2000 g·mol–1, PEG 2000),
and polyethyleneimine (PEI), branched (Mn 600 g·mol–1, PEI 600) were purchased from
Sigma-Aldrich. N-(3-Dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (EDC), N-hydroxysuccinimide (NHS), atenolol, atrazine, bezafibrate,
bisphenol A, bromothymol blue, naproxen, phenolphthalein, sulphamethoxazole,
oil red EGN, n-hexadecane, magnesium sulfate, magnesium
chloride, sodium sulfate, sodium dodecyl sulfate (SDS), sodium hydroxide,
glacial acetic acid, sodium phosphate monobasic dihydrate, phosphoric
acid 85%, and hydrochloric acid 37% were bought from Sigma-Aldrich.
Ethanol of 100% technical grade was bought from Boom B.V. n-Hexane 99+% was purchased from Acros Organics. Sodium
chloride (Sanal P) was received from AkzoNobel. Deionized water (DI,
1.0 μS·cm–1) was used for the preparation
of coagulation baths and Milli-Q water (Millipore, 0.6 μS·cm–1) was used to prepare solutions. The PSaMA solution
was dried for 16 h at 100 °C to obtain the solid polymer which
was used without further purification. All other chemicals were used
as received.
