| Abstract: | The amphiphilic copolymer monomethoxy poly(ethylene glycol)-poly(tert-butyl acrylate)(mPEG-b-PtBA) was synthesized via ATRP(atom transfer radical polymerization) with mPEG-Br as macroinitiator and CuBr/PMDETA as catalyst system.The structures of the synthesized copolymer were characterized by FT-IR,1H-NMR,and GPC.The influences of process conditions,such as the molar ratio of the monomer to macroinitiator,reaction time,reaction temperature and the molar ratio of catalyst to ligand,on polymerization were eva... |
