AB block copolymers of 2‐(2′,3′,4′,6′‐tetra‐ O ‐acetyl‐ β ‐D‐glucopyranosyloxy)ethyl acrylate (AcGEA) with styrene (St) have been synthesized by atom transfer radical polymerization using well‐defined bromo‐terminated polystyrene as a macroinitiator. An O ‐deacetylation of the precursor copolymers affords amphiphilic block copolymers, PSt‐ b ‐PGEA, with well‐defined glycopolymer segments and narrow molecular weight distributions ( M w / M n < 1.4). The examination of the aqueous solution of these amphiphilic block copolymers revealed the formation of ordered aggregates.
