Abstract
This paper describes an RP-HPLC method to characterize the ozonation products of polyethylene glycols (PEGs) (general formula HO(CH2CH2O)n-H) with original mass 5000. Samples with different pH and ozonation times were studied. The amounts of individual products up to n = 56, the percentage of PEGs as a final product and the molecular distribution (Mw/Mn) were calculated. The samples were concentrated by liquid-liquid extraction.
