dc.description.abstract	Lignin derivative (the commercial product -Protobind 2000) offered by the Granit Recherche Developement S.A. company, Lausanne-Schwitzerlandwas synthesized from annual plants. The present study’s aim was tomodify commercial lignins by the reaction of hydroxymethylation (produced in alkaline medium) and epoxydation (reaction with epichlorohydrin was performed in basic catalysis, aiming at increase the functionality) and to characterize the lignin derivatives chemical, spectral (1H NMR) and thermogravimetric analysis (TG). Studies have revealed some functional changes related to the difference in reactivity and reaction conditions.	en_US
