Synthesis of copper complexes of poly 2-(dimethylamino ethyl methacrylate)-b-poly (oligo (ethylene glycol) monomethylether methacrylate-b-poly 2-(dimethylamino ethyl methacrylate)

摘要

Three different ratios of double hydrophilic block copolymers poly [2-(dimethylamino) ethyl methacrylate]-b-poly(oligo(ethylene oxide) monomethyl ether methacrylate)-b-poly [2-(dimethylamino) ethyl methacrylate] (PDMAEMA-b-POEOMA-b-PDMAEMA) were synthesized by reversible addition fragmentation chain-transfer polymerization (RAFT), which was one of the controlled/living radical polymerization. The chain structure and component of such copolymers were characterized by spectroscopic studies (FTIR, ~1H NMR). The interaction of PDMAEMA-b-POEOMA-b-PDMAEMA copolymers with copper sulfate and copper chloride solution was studied. It was found that the anion (SO_4)~(2-), Cl~(-1) could have an effect on the structure and coordination of the Cu(II) complexes, which were confirmed by FTIR and scanning electron micrographs (SEM).
