    Abstract: A method of separating hemicellulose and cellulose by dissolution of hemicellulose from a hemicellulose-rich source, such as a pulp of any origin or from holocellulose. In the method, hemicellulose is dissolved in a solvent system comprising a cellulose solvent, which is either a ionic liquid or another direct cellulose solvent, and a molecular solvent (co-solvent), wherein said co-solvent does not dissolve cellulose, and wherein the solvent basicity and acidity of said ionic liquid or other direct cellulose solvent are adequately adjusted by the co-solvent. The present invention enables quantitative separation of cellulose and hemicellulose without any depolymerization and yield losses as occurring during conventional dissolving pulp manufacturing processes.

    Abstract: A method is conceived for producing hydrophobic lignocellulosics based on the graft copolymerisation of vinyl-type monomers onto the lignocellulosic backbone initiated by a redox couple initiator in aqueous medium. The green modification process can be carried out on any lignocellulosic material, for example, chemical, chemi-thermo-mechanical or thermo-mechanical pulps, bleached or unbleached. The technology disclosed in this invention yields individual lignocellulosic entities, for instance, hydrophobic pulp fibres, that can be used in combination with other fibres or polymers to produce nonwoven fibrous materials or composites. A significant aspect of the invention is that the modified lignocellulosic material possesses an efficient hydrophobic barrier and minimum interfacial energy to generate optimum adhesion when introduced to polymer resins. Hydrophobic lignocellulosics can have wide applications in products requiring high dimensional stability and excellent adhesion as in fibre-based packaging, decorative laminates, furniture and non-structural biocomposites.
