Abstract

The graft copolymers poly[(isobutene-co-(m,p)-chloromethylstyrene)-g-ethyleneimine)] HPG1 and poly((m,p)-chloromethylstyrene-g-ethyleneimine) HPG2 were obtained through the alkaline hydrolysis of the amphiphilic graft copolymers poly[(isobutene-co-(m,p)-chloromethylstyrene)-g-2-methyl-2-oxazoline] and poly((m,p)chloromethylstyrene-g-2-methyl-2-oxazoline), respectively. The subsequent quaternization of HPG1 and HPG2 with methyl iodide resulted in new polyelectrolyte graft copolymers which are soluble in water despite of the hydrophobic backbone.
