Abstract: A method for producing a rubber composition include a mixing step, a drying step, and a dispersion step. In the mixing step, an aqueous solution that includes at least one of oxycellulose fibers and cellulose nanofibers is mixed with rubber latex to obtain a first mixture. In the drying step, the first mixture is dried to obtain a second mixture. In the dispersion step, the second mixture is tight-milled using an open roll to obtain a rubber composition. The rubber composition does not include an aggregate that includes at least one of the oxycellulose fibers and the cellulose nanofibers, and has a diameter of 0.1 mm or more.

Abstract: In a method for preparing nanofibrillar cellulose, fibrous dispersion of ionically charged cellulose is repeatedly passed through a mechanical process of disrupting fibers into fibrils until the viscosity starts to decrease. The number average diameter of the nanofibrillar cellulose after the mechanical process is in the range of 2-10 nm, and the zero-shear viscosity is below 10 Pa·s, preferably below 1 Pa·s, when measured in the concentration of 0.5 wt-%. The nanofibrillated cellulose is low aspect ratio nanofibrillated cellulose (NFC-L).

Abstract: The present invention relates to an enhanced starch resin composition, methods of making the enhanced starch resin composition using environmentally benign, water-based processes, and products produced using the enhanced starch resin composition. The enhanced starch resin composition comprises a native starch and/or a waxy starch crosslinked with a multi-functional polycarboxylic acid. The starch resin composition is formed by a water-based reaction comprising using a non-toxic, water-soluble catalyst to catalyze esterification of the native starch and/or the waxy starch with the multi-functional polycarboxylic acid, thereby yielding a crosslinked starch resin composition having at least one enhanced mechanical property and/or reduced moisture absorption as compared to the native starch and/or the waxy starch.
