processo de tratamento quÍmico de materiais lignocelulàsicos e peÇa À base de fibras de material lignocelulàsico.

摘要

Chemical treatment of lignocellulosic material, particularly wood, by submitting the material to impregnation by an agent comprising hydrocarbon chains, chosen from mixed anhydrides (except mixed acetic/benzoic anhydride).The agent is adapted to ensure grafting by covalent bonding of many hydrocarbon chains to the material. An independent claim is also included for the treated material obtained.
