text: Some notable observations can be made from the 31P NMR spectra of the starting material (L2) and the lignins treated with polyester polyol (PL2) and PEG (L2+PEG).
text: The 31P NMR spectral analysis of the lignin treated with PEG confirmed the presence of a signal (triplet) at 147.1 ppm with a J-coupling constant of 10.73 Hz, which was due to the primary hydroxyl group of the PEG recorded in the aliphatic region of the treated lignin.
text: Additionally, the 31P NMR chemical shift for the lignin treated with PEG (L2+PEG) was recorded at 147.1 ppm, while the signal for the lignin treated with polyester polyol was recorded at 147.0 ppm.
