| 20100291398 | METHOD FOR TREATING LIGNOCELLULOSIC MATERIALS, IN PARTICULAR WOOD AND MATERIAL OBTAINED BY SAID METHOD - Process for the chemical treatment of lignocellulose materials, in particular of at least one piece of wood, characterized in that said materials are subjected to impregnation by a chemical agent comprising hydrocarbonaceous chains, this agent being chosen from mixed anhydrides, except for the mixed anhydride of acetic/benzoic acid, said agent being suitable for providing covalent grafting of a plurality of hydrocarbonaceous chains to said materials. | 11-18-2010 |
| 20100215863 | USE OF A MATERIAL RESISTANT TO THE DEVELOPMENT OF MICROORGANISMS - Use of a material based on lignocellulose materials, in particular a piece of wood or sawdust, subjected to a process of chemical treatment of said lignocellulose materials, consisting in subjecting said materials to a treatment with a chemical agent comprising hydrocarbon-based chains, this agent being chosen from mixed carboxylic anhydrides, said agent being suitable for ensuring grafting by covalent bonding of a plurality of hydrocarbon-based chains onto said materials, as a material which reduces or even prevents the development of microorganisms, such as fungi or molds, capable of degrading said lignocellulose materials. | 08-26-2010 |
| 20090280261 | USE OF A MATERIAL RESISTANT TO ATTACKS BY XYLOPHAGOUS INSECTS - Use of a material based on lignocellulose materials, in particular a piece of wood or sawdust, subjected to a process of chemical treatment of said lignocellulose materials, consisting in subjecting said materials to a treatment with a chemical agent comprising hydrocarbon-based chains, this agent being chosen from mixed carboxylic anhydrides, said agent being suitable for ensuring grafting by covalent bonding of a plurality of hydrocarbon-based chains onto said materials, as a material resistant to xylophagous insects. | 11-12-2009 |
| 20080311415 | Use of a Latex Composition Having at Least One Ureido Function For Adhering to Wood - The present invention concerns the use, in the surface treatment of waterproofed wood, of an aqueous dispersion comprising at least one latex obtained by emulsion polymerization of a mixture of monomers comprising at least one acrylic monomer B comprising at least one ureido function. | 12-18-2008 |
