The ABC miktoarm star terpolymer MPEG-PTHF (-PDMA) was synthesized by the combination of click chemistry, atom transfer radical polymerization (ATRP) and cationic ring opening polymerization (CROP). A block copolymer of poly(ethylene glycol) (PEG) and poly(N,N-dimethylaminoethyl methacrylate) (PDMA) which bears an azido at diblock junction (MPEG-N3 (-PDMA)) was first prepared by atom transfer radical polymerization. Then, an alkynyl-terminated narrow distributed polytetrahydrofuran (PTHF-Alk) was synthesized as another building block via cationic ring opening polymerization. The well-defined ABC miktoarm star shaped terpolymer was afforded by clicking MPEG-N, (-PDMA) onto the chain end of PTHF-Alk. The structure of the star terpolymer was characterized by the FTIR,NMR and SEC/MALLS. The self-assembly behavior of the polymer were investigated by dynamic light scattering (DLS) and transmission electron microscopy (TEM). This star shaped terpolymer consists of a hydrophobic PTHF chain, a hydrophiphilic PEG chain and another stimuli-responsive PDMA chain. It can self-assemble into micelles with different sizes and morphologies at various pH values, such as 5. 0,7. 4 and 9. 5. The micellar size also exhibits temperature-dependence at pH 7. 4 and 9. 5. The variation of size and morphology of the micelles with the solution pH and temperature is ascribed to the pH- and thermo-responsive properties of the PDMA block.

polymer materials are a class of materials of great importance for their peculiar chemical-physical properties. The basic principles of X-ray absorption fine structure (XAFS) which is promoted by synchrotron radiation, including extended X-ray absorption fine structure (EXAFS) and X-ray absorption near-edge structure (XANES) were introduced. Various XAFS methods were reviewed for applications in studies of polymers and related materials, including usual polymers, organometallic polymers, Pd-droped polymers, ionomers, carbon based materials, etc. These mentioned applications have showed the significance and advantage of XAFS in polymers and related materials field. It is confident that the promotion and growth in XAFS would bring more benefits in scientific research of polymers.
