Synthesis, thermal, rheological characteristics, and enzymatic degradation of aliphatic polyesters with lignin‐based aromatic pendant groups
(2019) In Journal of Polymer Science. Part A, Polymer Chemistry 57(23). p.2314-2323- Abstract
- This research aims to produce lignin‐based biodegradable polyesters with improved thermal quality. A series of aliphatic polyesters with lignin‐based aromatic side groups were synthesized by conventional melt‐polycondensation. Decent molecular weight (21–64 kg mol−1) was achieved for the polymerizations. The molecular structures and thermal and mechanical properties of the obtained polyesters were characterized. As a result, the obtained polyesters are all amorphous, and their glass‐transition temperature (Tg) depends on the size of the pendant aromatic group (31–51 °C). Furthermore, according to the TGA results, the thermal decomposition temperatures of the polyesters are all above 390 °C, which make them superior compared with commercial... (More)

Finally, rheological characteristics and enzymatic degradation of the obtained polyesters were also measured. (Less)
