Filed: 1994-05-31
Abstract: PURPOSE:To produce a high-molecular-weight aromatic polycarbonate improved in hue and excellent in heat stability by distilling off the by-product alcohol compound out of the reaction system under specified conditions. CONSTITUTION:An oligomer is formed by the melt reaction of an aromatic diol compound and a carbonic diester compound under ordinary or enhanced pressure at 100-200 deg.C in the presence of a transesterification catalyst. The temperature of the reaction system is then raised to 180-250 deg.C, and the pressure of the reaction system is gradually reduced by suction so that 50% of the by- product alcohol compound formed under a pressure of 400 to 1Torr is distilled out of the reaction system, giving a prepolymer. This prepolymer is subjected to melt polycondensation at 250-330 deg.C under a pressure of 1Torr or lower to produce an aromatic polycarbonate having a weight-average molecular weight of 10,000 to 60,000. The evacuation for removing the by-product alcohol compound out of the reaction system then is controlled so that the distillation rate may be 0.1-5% per min until 50% of the by-product alcohol compound is distilled off.

Title: Optical information recording medium
Inventor: KOBAYASHI TERUO
IPC: G11B7/24035
Filed: 1988-05-16
Abstract: PURPOSE:To prevent the oxidation corrosion of a thin recording film and to enable exact recording and reproducing of information for a long period of time even when the recording medium is rested in high-temp. and high-humidity environment by forming the thin recording film of a thin film which consists essentially of GeTe added with nitrogen and adjusting the nitrogen content in the optical thin recording film to the ratio lower than the average nitrogen content on the substrate side. CONSTITUTION:The GeTe material added with nitrogen is used as the essential component of the optical thin recording film 12 and the nitrogen content in the thin recording film 12 is adjusted to the ratio smaller than the average nitrogen content on the substrate 11 side. The oxidation corrosion of the thin recording film 12 progressing from a protective film 13 side is thereby powerfully prevented. Recording and reproducing of information are generally executed by allowing a light beam to enter the medium from the substrate 11 side and, therefore, the recording and reproducing characteristics of the optical information recording medium depend strongly on the properties of the thin recording film 12 on the substrate 11 side. The quantity of the deposited nitrogen which is a noise component on the substrate 11 side decreases and the good recording and reproducing characteristics are maintained if the nitrogen content of the thin recording film 12 on the substrate side is lower than the average nitrogen content.
