摘要: The present invention provides a method for producing resin beads which can provide various types of products, such as cosmetics, imparted with superior tactile impression, spreadability on the skin, transparency, and product stability, and which can be substituted for resin particles composed of a synthetic material derived from petroleum. The method is a method for producing resin beads containing a cellulose derivative as a main component. The production method includes: a suspension preparation step of mixing an oil phase containing the cellulose derivative and an organic solvent that dissolves the cellulose derivative, the organic solvent having a water-solubility of 0.1 to 50.0 g, and an aqueous phase containing a dispersion stabilizer, thereby preparing a suspension containing oil droplets containing the cellulose derivative and the organic solvent; and an oil droplet contraction step of adding water to the suspension, thereby contracting the oil droplets, wherein the water is added to the suspension in such a way as to satisfy the following expression (A) until a content of the organic solvent in the suspension becomes equal to or less than the water-solubility of the organic solvent. (W/S)/T≤1.00 (A), wherein W: an addition amount of water (parts by mass),
S: an amount of the suspension (parts by mass), and
T: a time (minutes) required for addition.-

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.
