Développement de nouveaux produits de traitement du bois basés sur l'utilisation de polycarbonates cycliques dérivés du glycérol

Abstract : The studies conducted during this thesis focuses on the development of various wood treatments based on the use of cyclic carbonates derived from glycerol, renewable source of raw materials in order to develop new methods of chemical modification of wood materials. The work proceeded in two stages: the first part of this work was to directly use the glycerol carbonate to develop treatments in the aqueous phase followed, after impregnating the wood product, a polymerization reaction for fixing the last to avoid leaching. The results have proved difficult to apply because of the reaction conditions too harsh, inconsistent with the thermal stability of wood. The second part related to the formation of polyurethanes in the wood without resorting to the use of isocyanates using condensation reactions of amines on cyclic di or polycarbonates. Various ways have been explored for the development of cyclic di or polycarbonate involving either the use of glycerol carbonate in a suitable junction module, or the action of dimethyl carbonate of polyglycerol. The formation of polyurethanes has been studied in a homogeneous phase and then applied to the treatment of wood. The results indicate, for the treatments performed, an increase of dimensional stability and resistance to wood brown rot fungus Poria placenta.
