چکیده
Synthesis and characterization of block copolymer PEG114-b-P4VP58 and PNIPAM93-b-P4VP58. Materials. Polyethylene glycol methyl ether (CH3O-PEG114-OH, Mn ~ 5000 and the polydispersity index, PDI = 1.05) was purchased from Fluka. The monomer 4-vinyl pyridine (Acros Organics, 95%) was purified by vacuum distillation. N-isopropylacrylamide (NIPAM, Acros Organics, 99%) was purified by recrystallization in a benzene/n-hexane mixture and dried in vacuum. CuCl was purchased from Aldrich and purified according to ref. ] 1
