The synthetic route included AGET ATRP copolymerization of 2-acrylamido-2-methyl-N-propanesulfonic acid (AMPS) and 2-hydroxyethyl acrylate (HEA) followed by modification of HEA units in the copolymers by 2-bromoisobutyryl bromide yielding macroinitiators which served for “grafting from” AGET ATRP of AMPS. Composition of the final and intermediate products was determined by 1H-NMR spectroscopy, and molecular weight and polydispersity of the resulting polyelectrolytes were estimated by size exclusion chromatography (SEC). Anionic comb polyelectrolytes with relatively low density of the grafts (5 – 7 grafting sites per 100 monomeric units of the mainchain) and relatively short side chains (9 or 25 AMPS units) were synthesized and characterized.
