Abstract: An oxidized β-1,4-oligoglucuronic acid, and a preparation method therefor and uses thereof. By using abundant cellulose in the natural world as the raw material, all 6-site hydroxyl groups of the cellulose β-1,4-polyglucose is oxidized into carboxyl groups to form glucuronic acid under the action of a sodium bromide (NaBr)-2,2,6,6-tetramethyl piperidine oxide (TEMPO)-sodium hypochlorite (NaClO) oxidation system, and the oxidized oligoglucuronic acid having an open ring at an end is prepared by controlling reaction conditions. The compound has obvious anti-cerebral ischemia activity, and can be developed into a potential anti-cerebral ischemia drug.

Abstract: A fine cellulose fiber composite containing fine cellulose fibers and a polymer having an ethylene oxide/propylene oxide (EO/PO) copolymer moiety or a propylene oxide (PO) polymer moiety, the fine cellulose fibers being connected with the polymer via an amide bond. The fine cellulose fiber composite of the present invention has high dispersibility in the resin and can exhibit an effect of increasing strength, so that the fine cellulose fiber composite is suitably used as various fillers, and the like. Also, the resin composition of the present invention containing a dispersion of the fine cellulose fiber composite can be suitably used in various industrial applications such as daily sundries, household electric appliance parts, wrapping materials for household electric appliance parts, and automobile parts.

Abstract: A process for manufacturing particles of water-absorbing material is provided. The process includes providing a powder bed composed of an absorptive powder comprising a water-absorbing polysaccharide onto a surface; releasing an aqueous solution from a solution dispenser so as to contact the powder bed, 5 thereby forming a solution-impregnated humid material; letting the solution-impregnated humid material agglomerate in substantially shear-less conditions to form an agglomerated humid material, the solution-impregnated humid material being supported by the surface; and drying the agglomerated humid material, thereby forming the particles.
