Polyvinyl acetate-co-polyvinyl tosylates and polyethylene-co-polyvinyl tosylates were synthesized via tosylation of poly(vinyl acetate-co-vinyl alcohol) and poly(ethylene-co-vinyl alcohol). Grafting of 2-methyl-2-oxazoline and 2-phenyl-2-oxazoline was performed using polytosylates as macroinitiators. Appropriate hydrolyzed analogues were prepared. The swelling properties and sorption capacity towards Cu2+ and Fe3+ of the graft copolymers and their corresponding hydrolyzed products were investigated.
