摘要： PURPOSE:To provide an essential recycling process whereby the aromatic dihydroxy compound and the diaryl carbonate obtained by the decomposition of a waste aromatic polycarbonate resin can be utilized again as starting materials for an aromatic polycarbonate resin. CONSTITUTION:This recycling process comprises step 1 of transesterifying a waste aromatic polycarbonate resin with an aromatic monohydroxy compound, step 2 of distilling off the aromatic monohydroxy compound from the product obtained by step 1, step 3 of distilling and recovering the diaryl carbonate compound from the high-boiling mixture as the residue from step 2, and step 4 of distilling and recovering the aromatic dihydroxy compound from the still- higher-boiling mixture as the residue from step 3.

摘要： PURPOSE:To again use decomposed aromatic polycarbonate resin as a raw material by specifying a length of a tube for a bore of the tube at a predetermined temperature, and decomposing the resin by a tube type reactor under conditions for holding a liquid state in a coupling manner. CONSTITUTION:A tube type reactor (pipe reactor) decomposes to react aromatic polycarbonate resin with aromatic monohydroxy compound has a length L [m] of a tube, L=-10D to 50,000D or preferably L=20 to 10,000D or particularly preferably L-50 to 5,000D, where an inner diameter of the tube of the reactor is D [m]. In this case, a decomposing reaction temperature is 300 to 300 deg.C, or preferably 240 to 280 deg.C. The resin can be continuously decomposed under conditions for holding a liquid state in this reactor.

摘要： PURPOSE: To recover a polycarbonate resin of good quality in high yield from waste of a photomagnetic recording disk (MOD) having a polycarbonate resin substrate. CONSTITUTION: Waste of a photomagnetic recording disk (MOD) having a polycarbonate resin substrate is subjected to wet grinding while brought into contact with a base aq. soln. or water to obtain flakes with an average particle size of 0.5-10mm. These flakes are brought into contact with a base aq. soln. with a concn. of 9wt.% or less to be treated within a temp. range of 30 - below 75 deg.C and the treated flakes are neutralized by an acid aq. soln. to be washed and dried to efficiently recover a polycarbonate resin of high quality.

摘要： PURPOSE: To easily produce the subject particles having high flowability, bulk density, remeltability and solubility, handleability, transportability, etc., and useful for lens, etc., on an industrial scale by contacting a polycarbonate solution with hot gas while keeping the solution in the form of filaments and cutting the product. CONSTITUTION: The objective particles can be produced by contacting (A) a methylene chloride solution of a polycarbonate resin with (B) a hot gas such as steam while keeping the solution in a filament form and cutting the product. For example, a methylene chloride solution having a polycarbonate resin concentration of 5.0-50wt.% is prepared at 30-100 deg.C and extruded through a spinneret having an average nozzle diameter of 0.5-5mm in the form of continuous filaments into steam as the hot gas atmosphere while keeping the filament form. The filament is brought into contact with the gas for 1-15min and the solidified filaments are cut with a rotary cutter having metal blades, a pressurized water cutter, etc., to obtain the objective particles.

摘要： PURPOSE:To make the substrate lightweight, to simplify the product process, to improve yield and to reduce the cost by successively laminating a polarizing film, a phase-contrast film and a transparent conductive film such as ITO film to integrate the substrate. CONSTITUTION:A polarizing film, phase-contrast film and transparent conductive film are successively laminated and integrated to for the electrode substrate. A thin film layer of indium oxide (ITO) added with tin as the impurity is preferable as the transparent conductive film from the standpoint of transparency and conductivity. Meanwhile, when a supporting film is interposed between the phase-contrast film and transparent film, handling is facilitated in the production process of the substrate, and a degree of freedom in production is favorably increased. In this case, the polarizing film, phase-contrast film and supporting film are firstly laminated, and then the transparent conductive film is formed on the supporting film. Furthermore, the reliability of the liq. crystal display panel is improved by laminating a protective film on the surface of the phase- contrast film or supporting film to be coated with the transparent conductive film.
