Abstract: PROBLEM TO BE SOLVED: To obtain a (meth)acrylic acid copolymer low in the content of highly hygroscopic impurities and preventing a powdery detergent including the copolymer from discoloration, and to provide a method for producing the copolymer. SOLUTION: The method for producing the (meth)acrylic acid (co)polymer comprises polymerizing a monomer, essentially i.e. acrylic acid, methacrylic acid or salt(s) thereof using a persulfate and bisulfite in the presence of a water-soluble metal salt at ≤50°C. The (meth)acrylic acid copolymer thus obtained has the following characteristics: the content of a byproduct formed by addition of the bisulfite to the (meth)acrylic acid ( salt ) is ≥1 pt. mass based on 100 pts. mass of the (co)polymer, the content of a hydroquinone compound is ≥0.02 pt. mass based on 100 pts. mass of the (co)polymer, and the drying characteristic parameter defined by a specific formula is ≤75%.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an acrylic acid-based polymer which is not colored, even when subjected to a heat history comprising heating and drying the acrylic acid-based polymer obtained by a polymerization in the presence of a redox initiator and an alkali preparation solution containing an inorganic salt such as sodium carbonate, sodium sulfite, sodium sulfate, zeolite, or sodium chloride in a process for producing a detergent composition.
SOLUTION: This method for producing the acrylic acid-based polymer comprises polymerizing monomers containing acrylic acid or its salt containing a quinone compound as a polymerization inhibitor in the presence of a redox initiator, and then reducing the content of the quinone compound until the content of the quinone compound contained in the obtained acrylic polymer becomes ≤20 mg per kg of the acrylic acid constituting the acrylic polymer.

Abstract: PROBLEM TO BE SOLVED: To provide a method for easily producing a polymer particle dispersion in which the polymer particles are dispersed in a non-aqueous solvent. SOLUTION: This method for producing a polymer particle dispersion in which the polymer particles are dispersed in a non-aqueous solvent comprises subjecting a polymerizable monomer having a vinyl group to a suspension polymerization in the presence of an ammonium salt type surfactant as a dispersing agent in an aqueous solvent, subjecting the obtained polymer suspension to the addition of the non-aqueous solvent and the ammonium salt-removing treatment of the ammonium salt type surfactant, and dehydrating the product before, after or during the ammonium salt-removing treatment.

Abstract: PROBLEM TO BE SOLVED: To obtain particles having a narrow particle diameter distribution and each having a hydrophobic surface by subjecting a vinyl monomer to dispersion polymerization in at least one solvent selected from the group consisting of hydrocarbon solvents and silicone solvents in the presence of a dispersant comprising an aminated silicone. SOLUTION: The dispersant used comprises an aminated silicone having a modifying group represented by the formula (wherein n is 3 to 20; and A and B are each H, a 1-22C hydrocarbon group, a 1-22C aminoalkyl, etc.), such as a 3-aminopropyl group, with an amine equivalent of 300-50,000 g/mol and a viscosity (25 deg.C) of 50-100 cSt. At least one solvent selected from hydrocarbon solvents, such as hexane and toluene, and silicone solvents is mixed with a vinyl monomer, such as an alkyl acrylate, in an amount sufficient to provide a concentration of 2-30 wt.%, an aminated silicone dispersant in an amount of 0.1-20 wt.% based on the monomer, a polymerization initiator comprising, e.g. lauroyl peroxide in an amount of 0.1-10 wt.%, and a chain transfer agent, and the mixture is subjected to dispersion polymerization at room temperature to 150 deg.C to give polymer particles having a diameter of 0.3-20 μm.

Abstract: PROBLEM TO BE SOLVED: To obtain a cosmetic excellent in emulsion stability, having a refreshing feeling in use free from greasiness, comprising a component containing an oil phase, a lower alcohol and water and a preferably polymer compound as an emulsifying agent or an emulsifying auxiliary. SOLUTION: This cosmetic is obtained by adding a polymer compound having orientation to a system composed of an oil phase (preferably silicone oil), a lower alcohol and water. A copolymer containing both a hydrophilic segment and a segment of an organopolysiloxane is preferable as the polymer compound. An end-blocked Nacylalkyleneimine, polyalkylene glycol, acrylic acid, etc., are preferable as hydrophilic segment. Preferably, the weight ratio of the hydrophilic segment and the segment of the organopolysiloxane is 1/50 to 20/1 and the weight-average molecular weight of the polymer compound is 500 500,000. Preferably, the composition comprises 10-90wt.% of the oil component, 0.05-10wt.% of the polymer compound and 1-40wt.% of the lower alcohol.
