Provided is a method of producing a polycarbonate resin pellet containing a polycarbonate resin serving as a component (A), a silicone compound serving as a component (B), and an ester of an aliphatic carboxylic acid having 12 to 22 carbon atoms and glycerin serving as a component (C), the production method including a step including introducing a blend containing the component (A), the component (B), and the component (C) into an extruder, and melt-kneading the blend in the extruder under such a condition that a temperature of a molten resin at an outlet of the extruder is 260&#xb0; C. or more and 325&#xb0; C. or less, followed by extrusion molding to provide a polycarbonate resin pellet, the resultant polycarbonate resin pellet containing 0.01 part by mass or more and 0.25 part by mass or less of the component (B), and 0.015 part by mass or more and 0.25 part by mass or less of the component (C) with respect to 100 parts by mass of the component (A).

Method of manufacturing polycarbonate resin pellets

Provided is a polycarbonate resin, including, as a raw material, a bisphenol A having 100 ppm by mass or less of isopropenylphenol and 250 ppm by mass or less of 2-(2-hydroxyphenyl)-2-(4-hydroxyphenyl)propane, each detected after heating in air at 175&#xb0; C. for 1 hour.

Polycarbonate resin, and polycarbonate resin composition

An extrusion pelletizer for a polycarbonate resin includes: an extruder; a cooling unit; and a cutter. The extruder includes a cylinder top, a first adapter, a polymer filter unit, a second adapter, and a die head. The polymer filter unit includes a plurality of stick-shaped filter elements therein. A temperature of the second adapter is set to be lower than a temperature of the polymer filter unit. The cooling unit and the cutter are disposed under an atmosphere in which air cleanliness defined in accordance with JIS B 9920 is any one of class 1 to class 7.

Extrusion pelletizer for polycarbonate resin and method for extrusion-pelletizing polycarbonate resin

Provided is a polycarbonate-based resin composition, including: (A) a polycarbonate-based resin including 10 mass % to 100 mass % of a specific polycarbonate-polyorganosiloxane copolymer (A-1) and 0 mass % to 90 mass % of a polycarbonate (A-2) except the copolymer (A-1); and (B) an additive, the polycarbonate-based resin composition containing sodium at a content of 0.5 ppm or less.

Polycarbonate-type resin composition and molded article

A windowis a two-color molding comprising a transparent sectionand a frame sectionintegrated with the transparent section, the frame sectionand the transparent sectionare formed with a first material and a second material respectively, and the first material is a thermoplastic resin with the linear thermal expansion coefficient in the MD direction lower by 1&#xd7;10to 3&#xd7;10(mm/(mm.K)) than that of the second material, and also with the MD/TD ratio for the linear thermal expansion coefficient in the range from 0.6 to 1.
