POROUS CELLULOSE AGGREGATE AND MOLDING COMPOSITION THEREOF

摘要

A porous cellulose aggregate characterized by having a secondary aggregate structure resulting from aggregation of cellulose primary particles, having an intraparticulate pore volume of 0.265 to 2.625 cm³/g, containing I-type crystals and having an average particle diameter of over 30 to 250 µm, a specific surface area of 0.1 to less than 20 m²/g, a repose angle of 25° to less than 44° and a swelling degree of 5% or more, and characterized by having the property of disintegrating in water.
