| abstract |
The present invention provides an analytical method capable of easily quantifying the content of structural units in a polyester that is hardly soluble in an organic solvent. A first step of depolymerizing a polyester which is hardly soluble in an organic solvent and is obtained by polymerizing a known monomer in bisulfuric acid, and a depolymerized product obtained in the first step are combined with nuclear magnetic resonance. A second step of measuring a 1 H-NMR spectrum by spectroscopy and quantifying the content of structural units in the polyester from the measurement results. [Selection] Figure 2 |
