Abstract: The present invention relates to a method of making a foamed cellulosic fiber-thermoplastic composite article. The method includes the steps of providing a copolymer composition, combining the copolymer composition and cellulosic fibers, applying heat, mixing energy and pressure to form a foamable mixture, and forming the foamable article in a molding or extruding operation. The method is characterized in that at least 10% of the cellulosic fibers have been thermally modified prior to being combined with the copolymer composition.

Abstract: An object of the present invention is to provide a technology of dispersing cellulose readily in a hydrophobic substance such as a resin by treating cellulose being a hydrophilic substance in a system that contains water as a main medium with a polymer dispersant, which has been developed for dispersing a fine and hydrophobic substance such as a pigment, in a simple and efficient manner without conducting surface modification of nanocellulose or other treatments. The object is solved by a process for producing a readily dispersible cellulose composition, the process including dissolving a polymer dispersant having a block copolymer structure having a resin-affinitive segment A and a cellulose-adsorptive segment B in a hydrophilic organic solvent solution, adding a surface active agent to the resultant solution, thereafter adding water to the resultant mixture to prepare an aqueous dispersion treatment agent containing the polymer dispersant, and adding the obtained aqueous dispersion treatment agent to cellulose in a water-containing state or in a dry state, thereby obtaining a readily dispersible cellulose composition. The object is also solved by a process for producing an aqueous dispersion treatment agent for use in the process for producing a readily dispersible cellulose composition, the readily dispersible cellulose composition, and a cellulose-dispersed resin composition using the readily dispersible cellulose composition.

Abstract: The lubricious hydrophilic coatings of the invention are significantly more lubricious when wet than when dry, are adherent to a variety of substrates, and are resistant to removal by wet abrasion. In one embodiment, the coatings include a hydrophilic polyolefin such as polyvinyl-pyrrolidone and a water-insoluble stabilizing polymer such as a cellulose ester. The coatings may also include an adherent polymer and a plasticizing agent. The coating may be applied by preparing a solution of the stabilizing polymer and a solution of the hydrophilic polyolefin, and coating the substrate first in one then the other. Alternatively, both the stabilizing and hydrophilic polymers may be dissolved in a single solvent system and applied to the substrate in a single step. In another embodiment, only a solution of a hydrophilic polyolefin is applied directly to the substrate. In this embodiment, the solution of the hydrophilic polyolefin includes a cosolvent which acts as a solvent for both the hydrophilic polyolefin and the substrate. The coatings of the invention may be applied to biomedical devices and implants such as catheters, condoms, and nasogastric and endotracheal tubes.
