    • Provided is a low-cost, highly active, environmentally friendly living radical polymerization catalyst which does not require a radical initiator. An organic compound having an oxidation-reduction capability is used as a catalyst. Even if a radical initiator is not used, a monomer can be subjected to a radical polymerization to obtain a polymer having narrow molecular weight distribution. The cost of the living radical polymerization can be remarkably reduced. It is made possible to prevent adverse effects of using a radical initiator. The present invention is significantly more environmentally friendly and economically excellent than conventional living radical polymerization methods, due to advantages of the catalyst such as low toxicity of the catalyst, low amount of the catalyst necessary, high solubility of the catalyst, mild reaction conditions, and no coloration/no odor (which do not require a post-treatment for a molded article), etc.

    • 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.
