Abstract

Poly(styrene-b-2-vinyl-1-methylpyridinium iodide-b-ethylene oxide) (PS-PVMP-PEO) was synthesized by quaternizing poly(2-vinyl pyridine) block of poly(styrene-b-2-vinyl pyridine-b-ethylene oxide) with iodomethane. Then, PS-PVMP-PEO/ tungstate hybrid micelles were prepared by binding tungstate to the PVMP block at neutral pH in aqueous solutions. The hybrid micelles were characterized by various techniques like dynamic light scattering, scanning electron microscopy, transmission electron microscopy, and zeta-potential measurements. It was found that the PS-PVMP-PEO/tungstate hybrid micelles have a spherical structure with a hydrodynamic diameter ranging from 80 to 120 nm depending on the amount of the incorporated tungstate.
