In a context of renewable molecules valorization, new molecular architectures and polyols have been developed from sorbitol and various biobased building-blocks with respect to the green chemistry principles. Several polyesters polyol have been synthesized from controlled esterification reactions in bulk conditions. Thanks to the used of variable size diols (C2 to C12) monomers, polyols final viscosity and hydroxyls values were tuned until the obtaining of suitable properties for polyurethanes foams elaborations. Thus, semi-flexible polyurethane foams and rigid polyisocyanurate foams were formulated with fast foaming kinetic profiles (less than 3 min). Rigids polyisocyanurates foams exhibit excellent mechanical and thermal properties, in g...
