摘要： 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.

摘要： Disclosed are an aqueous pigment dispersion containing at least a pigment, water, a high-molecular dispersant, and an alkali. The high-molecular dispersant is a diblock polymer having a formula (1) of A-B or a triblock polymer having a formula (2) of A-B-C. The diblock or triblock polymer is a diblock or triblock polymer obtained by polymerizing addition-polymerizable monomers with a radical generator while using an organic iodide as a polymerization initiating compound and an organic phosphorus compound, organic nitrogen compound or organic oxygen compound as a catalyst. Also disclosed are a production method and use of the aqueous pigment dispersion. With the high-molecular dispersant obtained by a simple living radical polymerization process free of the problems of conventional living radical polymerization and having a precisely-controlled molecular structure, the aqueous pigment dispersion can be obtained with the pigment dispersed in it.

摘要： An object of the present invention is to provide a high-performance polymer dispersant that can be applied to cellulose being a hydrophilic substance, and another object of the present invention is to provide a technology for practical application of obtaining a cellulose-dispersed resin composition that realizes stable dispersion of cellulose in a simpler manner and in an environmentally conscious manner that never uses a large amount of organic solvents when the polymer dispersant for cellulose is applied to cellulose and disperses the cellulose in a thermoplastic resin. These objects are achieved by providing a polymer dispersant for cellulose, being a polymer compound including a block copolymer structure having a resin-affinitive segment A and a cellulose-adsorptive segment B, the polymer compound synthesized by a reversible chain transfer catalyzed polymerization (RTCP) method not using any of a heavy metal, a nitroxide compound, and a sulfur-based compound, using an organic iodine compound as an initiation compound, and using a phosphorus compound, a nitrogen compound, an oxygen compound, or a carbon compound as a catalyst.

摘要： Provided is an electrically conductive resin composition with which the characteristics inherent in a thermoplastic resin are easily retained and which exhibits more excellent electrical conductivity even if the blending amount of an electrically conductive filler is small. This electrically conductive resin composition contains a thermoplastic resin, such as a polycarbonate or a polyolefin, and an electrically conductive filler, such as a carbon nanotube. This electrically conductive resin composition further contains a dye, such as a perinone-based dye or a disazo-based dye, which is a component for improving electrical conductivity, and this electrically conductive resin composition can be obtained by kneading or molding a raw material mixture containing a thermoplastic resin, an electrically conductive filler, and a dye under a condition of a temperature equal to or higher than the melting point of the thermoplastic resin.
