Mécanique des matériaux biosourcés. De l'extraction au recyclage, conséquences sur les propriétés effectives.

Current global stakes urge chemical industry to a sustainable chemistry and particularly to a double substitution: the use of renewable resources instead of fossil resources and the substitution of harmful reactants by less-harmful ones. We developed a real chemical toolbox based on thiol-ene coupling, ring opening reaction, amidification/esterification to synthesize a library of biobased building blocks with various functions and functionality from vegetable oils and natural phenols. The synthesized building blocks reported in this contribution led to polymers with various properties: low Tg polymers for coating or higher Tg polymers for composites.
