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: 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.
text: Much like the lignins treated with polyester polyol, the content of several hydroxyl units in the treated lignin with PEG decreased considerably.
