摘要: Kraft lignin (KL) is extensively produced in industry but mainly burned as fuel. To broaden its use, KL was grafted with dodecyl glycidyl ether to alter thermal properties. The reaction of (DGE) analyzed using nuclear magnetic resonance (NMR), Fourier infrared spectroscopy (FT-IR) and elemental analysis. Alternatively, methylated mask phenolic hydroxy groups investigate how impact the grafting alkyl chain DGE onto (methylated lignin, MKL). methylation facilitated molecular weight enhancement stability reduction via DGE. influence chains on structural properties MKL studied thermogravimetric analysis differential scanning calorimetry Our data suggest that, due their high weights lower glass transition temperatures, derivatives may be promising feedstocks for composite production.
