Abstract	A new heterobifunctional initiator, 2,3-bis(2-bromo-2-methylpropionyloxy) succinic acid, was synthesized and used in preparation of A2B2 miktoarm star copolymers, (polystyrene)2(poly(ε-caprolactone))2, by combination of atom transfer radical polymerization (ATRP) and Controlled ring-opening polymerization (ROP). The structures of products were confirmed by the 1H NMR, 13C NMR, FT–IR, elemental analysis, differential scanning calorimetry (DSC), and gel permeation chromatography (GPC). GPC traces show that the obtained polymers have a relatively narrow molecular weight distribution. The compositions of resulting miktoarm star copolymers were very close to theoretical.A new heterobifunctional initiator was synthesized and successfully used in the preparation of miktoarm star block copolymers via a combination of Controlled ring-opening polymerization and atom transfer radical polymerization, in a sequential process.
