titleOfInvention | Method for producing granular polyarylate |
abstract | (57) [Summary] [Problem] To recover a fine powder of polyarylate from a fine powder of polyarylate using an inexpensive apparatus without mixing the recovered fine powder of the polyarylate into the product as it is and without re-dissolving the fine powder in an organic solvent. The present invention provides a method for producing a polyarylate. A water-methylene chloride mixed solution containing methylene chloride which is kept at a temperature of 10 to 60 ° C. and is not liquid-liquid phase-separated under normal pressure or reduced pressure in a stirring tank, and has a particle diameter of 100 μm. The polyarylate fine powder is supplied to form a slurry, and the fine powder is aggregated in the slurry to obtain particles having an average particle diameter of 500 μm or more. |
