Popis:	Amidoalkylation of polysulfone (PS) with N-chloromethylphthalimide (CMPi) to polymer 2/2a (PiPs), followed by hydrazinolysis of PiPs in CHCl3 with neat N2H4 + H2O (RT 3 days) to aminomethylpolysulfone (3, AMPS). Condensation of AMPS with 4-chlorosulfonylbenzo-18-crown-6 produced B18C6AMPS. Okawara-type condensations with diglycydyl glycols (5) led to azacrown polysulfone polymers 6d, and polystyrene azacrown polymers 6a–6c. Products were characterized by 270 MHz 1H-NMR, thermogravimetric (TGA) and DSC analysis. Insoluble aminomethylpolystyrene beads were used as model supports to study the Okawara-type reaction with diglycydyl ethers and the products showed thermoregulated complexation of alkali salts on polymers 6b and 6c. Polysulfone membranes were prepared from B18C6AMPS and transport of K+ in a liquid membrane-type experiment was demonstrated.
