Controlled free radical polymerization of a sugar‐carrying acrylate, 3‐ O ‐acryloyl‐1,2 : 5,6‐di‐ O ‐isopropylidene‐α‐ D ‐glucofuranoside (AIpGlc), was achieved in p ‐xylene at 100°C by using a di‐ tert ‐butyl nitroxide (DBN)‐based alkoxyamine as an initiator and dicumyl peroxide (DCP) as an accelerator. The polymerization gave low‐polydispersity (1.2 < M w / M n < 1.6) polymers with predicted molecular weights. The same approach with a DBN‐capped polystyrene (PS‐DBN) as an initiator afforded block copolymers of the type PS‐ b ‐PAIpGlc. The acidolysis of the homopolymers and block copolymers gave well‐defined glucose‐carrying polymers PAGlc and PS‐ b ‐PAGlc, respectively. These amphiphilic PS‐ b ‐PAGlc block copolymers were observed to exhibit microdomain surface morphologies that differ for different copolymer compositions. This success opens up a new, simple route to the synthesis of well‐defined sugar‐carrying polymers of various architectures.
