Until recently the large majority of chemistry building-blocks are stemmed from petroleum resources. However, due to increasing scarcity of oil resources leading to a surge in raw materials prices combined to environmental concern and impact on human health, renewable and viable alternatives are urgently needed. In this purpose, the use of naturally-occurring and renewable building blocks for the chemistry in general and for the polymer science, in particular, is of great interest. Specifically, polysaccharides, such as cellulose and lignin, that are found in all plants cell are particularly good candidates for the replacement of fossil-based raw materials through their multifunctionality and are already considered as a versatile chemical platform. Among these interesting sources of raw materials, hemicelluloses represent 15% to 35% of plants and wood but is nevertheless an underexploited source of bio-based building blocks due to difficult extraction from the cell wall. Furthermore, a great majority of the extracted hemicelluloses are low-molecular-weight oligomers and cannot be valorized as such. In the present work, we relate the use of low-molecular-weight hemicelluloses as a renewable building-block and its use for the design and the synthesis of new biopolymers through chain extension. Molecular, thermal and thermo-mechanical characterizations of the obtained polymers will be detailed.
