摘要：

Alkyloxy and aryloxy terminated polyethylene oxides are analyzed with respect to their terminal groups by liquid chromatography at the critical point of adsorption. The molar mass distribution of the main functional fraction is determined by a modified size-exclusion chromatography technique using matrix assisted laser desorption/ionization mass spectrometry as an additional detector. The results are correlated with data obtained by supercritical fluid chromatography and mass spectrometry.
