This work describes a synthesis of linear diblock and triblock copolymers of 2-vinyl pyridine (2VP) and ethylene oxide (EO). The overall synthetic approach involved polymerization of 2VP, followed by polymerization with EO. Neutralization of the reactive end-groups of the living diblock P2VP-b-PEO(-)K(+) produced the diblock copolymer P2VP-b-PEO. Reaction with dibromoxylene in the presence of CsI led to the triblock copolymer, P2VP-b-PEO-b-P2VP. The triblock copolymers were separated by fractionation at 40 degreesC. Copolymers were characterized by size exclusion chromatography, light scattering and nuclear magnetic resonance spectroscopy. Characterization showed that the materials have high molecular and compositional homogeneity.
