A simple preparative‐scale adsorption chromatographic method for separating a commercially available polyethylene mono‐alcohol from its non‐functional polyethylene impurities has been established using silica as the stationary phase and toluene at 75°C as the isocratic eluant. Characterization of the chromatographic fractions by 1 H‐NMR spectroscopy also provided unexpected comprehensive information on the molecular structure and molar mass distribution of the polyethylene mono‐alcohol. © 2012 Wiley Periodicals, Inc.
