METHOD FOR MANUFACTURING MOLDED ARTICLE

摘要

A molded article that improves heat resistance of a polycarbonate resin during molding and has excellent hue and transparency; specifically, a method for manufacturing a molded article, wherein a powder and granular material is melted at a temperature of 280-380°C and formed into a molded article. The method is characterized in that the powder and granular material satisfies the following conditions (I) and (II). (I) When 100 parts by weight of the powder and granular material is cleaned with 100 parts by weight of 1N nitric acid aqueous solution, the Fe compound eluted into the cleaning solution of the 1N nitric acid aqueous solution is 1-100 ppb, in terms of the Fe atom relative to the powder and granular material. (II) The powder and granular material, (A) with respect to 100 parts by weight of a polycarbonate resin (component a), (B) contains 0.00010-0.5 parts by weight of a specific phosphorus compound (component b).
