These samples were depolymerized with various oxide catalysts such as MgO, ZnO, Sn02 and SbfDs. The resulting glycolide was analyzed by gas chromatography in different eluents - acetonitrile and hexafluoroisopropanol. It was shown that modification of glycolic acid oligomers by polyhydric alcohols reduces the content of hydroxyl containing impurities in raw glycolide.
