AbstractPoly(ethylene oxide)-b-poly(2-hydroxyethyl methacrylate) (PEO-b- PHEMA) was synthesized by successive atom transfer radical polymerization (ATRP) of 2-hydroxyethyl methacrylate（HEMA） monomer using PEO-Br macroinitiator as initiator, CuBr/CuBr2 and 2,2‟-bipyridyl (bpy) as catalyst and ligand. IR, 1H NMR, and GPC analysis indicate that PEO-b-PHEMA block copolymer with low polydispersity index (Mw/Mn≈ 1.1) has been formed. Selfassembly of this double hydrophilic block copolymer in the selective solvent and water was also studied. Owing to the high hydrophilic nature of the PEO and PHEMA blocks, this double hydrophilic block copolymer cannot disperse well in water. So block copolymer was modified by part esterification of PEO-b-PHEMA with acetic anhydride, which increased the hydrophobic group of the PHEMA block. The TEM results show that this block copolymer spontaneously form well-defined micelles in water.

The well-defined block copolymer PMMA-b-PS was prepared by two-step ATRP in emulsion system. GPC results indicate that Mn increased linearly with conversion and polydispersity remained relatively narrow. It presents the characteristics of living polymerization in emulsion system. FT-IR demonstrated that block copolymer PMMA-b-PS could be successfully synthesized by ATRP with macroinitiator PMMA-Cl in emulsion system. The morphological characteristic of the self-assembly depends on the block copolymer concentration and transforms between spheres and rodlike micelles. The property indicates a perfect potential application in drug delivery materials.
