摘要

Method for producing a modified surface cellulosic material, method of drying a modified cellulosic material, modified surface cellulosic material, modified cellulosic material, uses of modified surface material, hydrophobic materials, solven Not polar, methods to produce enhanced hydrophobic material, methods to produce a non -polar solvent modified by reology,And hydrophobic cellulosic material are provided with modified cellulosic materials with a surface modifier to promote compatibility with a hydrophobic material and methods to produce modified surface cellulosic materials. Methods include providing a fluid pulp from a cellulosic material and adding a surface modifier to the PAIt's fluid. The surface modifier can be added to the fluid folder in a soluble and precipitated form by adjusting pH. The modified surface cellulosic material can be dried by solvent and /or dry using conventional drying methods to increase hydrophobicity. To dry the surface -modified cellulosic material with solventA solvent is added to an aqueous fluid paste of the modified surface cellulosic material to form an azerop. Azerop has a boiling point which is smaller than the boiling point of the solvent. The fluid paste is distilled to remove the azerop from the modified surface cellulose material. The solvent is removed from the modified surface cellulose material.
