This was achieved using chloro-terminated PEG as a macroinitiator. Further, the ATRP was performed using 4-VP as a second forming block in the presence of CuCl/PMDETA as a catalyst system. The successful formation of MeOPEG-b-P4VP block copolymers was proved by 1H NMR with the presence of all characteristic signals arising from PEG and 4-VP units. The GPC results showed the preparation of well-defined block copolymers with low dispersity, which confirms the controlled character of radical polymerization. The thermal properties of thus prepared copolymers were characterized by TGA analysis.enArticle
