Description

1251608 Ministry of Economic Affairs Intellectual Property Office a (Industrial Consumer Cooperatives Printed A7 B7 V. INSTRUCTIONS (i) The present invention relates to a polycarbonate composition having a good mold release property, a substrate for an optical recording medium, and an optical recording medium. In the technology, polycarbonate has a good color, transparency, and mechanical strength of engineering plastics. In recent years, its use is a processor of a variety of molded products, which has good mechanical strength, and thus serves as a support for optical disk substrates and electrochemical products. It is used in a large number of molded materials which are light and thin and have a high surface area ratio. The molded article is generally molded by injection molding using a mold, but in the molding method, when the molded article is demolded, the molded product is removed. The poor moldability and the hindrance to production efficiency are the doubts of the prior art. The larger the scale of production, the more serious the problem. Especially the optical disc substrate is usually used to make the signal imprinted on the printer correctly copied on the polycarbonate substrate, so that the injection molding machine After the temperature of the cylinder is made at a high temperature of 3 5 0 to 400 ° C, the fluidity of the resin is improved. Therefore, the printer of the device is The mold temperature must also be set at a high temperature of 80 ° to 120 ° C. However, when the mold temperature is high, the mold release property of the polycarbonate molded product is lowered, the mold release is incomplete, and the printing property is poor. In order to prevent this problem, it is necessary to sufficiently cool the mold, and before the mold release, however, the molding cycle becomes longer and the productivity is lowered. For this reason, in recent years, it has been strongly expected to be shot. A polycarbonate which develops a good mold release property during molding. An effective method for adding a release agent to improve the mold release property of polycarbonate is known in the prior art. As a release agent, a so-called lubricant is generally known. Various compounds are disclosed in Japanese Patent Publication No. 4-7 - 4 1 0 9 2 for the use of higher aliphatic carboxylic acids, higher aliphatic alcohols, or esters with polyols or paper grades for Chinese national standards (CNS).

The addition of the release agent is not ideal as the known cost surface and the number of steps are increased.

Invention description (7) (Please first Read the precautions on the back and fill out this page.) When the number of people jumps out of this range, the optical deviation caused by changes in fluidity, etc., is not ideal. In other words, the substrate for an optical recording medium using the aromatic polycarbonate in the range of (μz / Mw) can be used as a substrate having excellent optical characteristics and reproducibility as a substrate for an optical recording medium. The adjustment of the molecular weight distribution (M z / M w ) can be adjusted by the addition of the terminal blocking agent and the polymerization conditions. For example, in the case of melt polymerization, the molar ratio of the aromatic dihydroxy compound to the carbonic acid diester of the raw material is changed, and the polymerization condition (temperature/vacuum degree/residence time) is changed, and the molecular weight distribution (M z / M w ) can be changed. . The average molecular weight of the ruthenium is determined by the molecular weight distribution measured by the gel permeation color. Further, the aromatic polycarbonate has a melt viscosity stability of 5% or less. Melt viscosity stability refers to the cutting speed of 1 r a d / s e c under nitrogen flow, and the change of melt viscosity measured at 30 ° C for 30 minutes is evaluated by absolute enthalpy, and the rate of change of 1 minute represents the number. This melt viscosity stability can be obtained by adding a melt viscosity stabilizer to the polycarbonate after polymerization. Printed by the Intellectual Property Office of the Intellectual Property Office of the Ministry of Economic Affairs. The melt viscosity stabilizer also has the effect of deactivating some or all of the polymerization catalyst used in the manufacture of polycarbonate. As a method of adding the melt viscosity stabilizer, the polycarbonate of the reaction product may be added in a molten state, and the polycarbonate may be granulated and then melted and then added. In the former, the reaction product polycarbonate in the reaction tank or in the extruder may be added in a molten state, and the polycarbonate obtained after the polymerization is passed through the extruder through the reaction vessel, and then granulated, and then added. After the melt viscosity stabilizer is mixed, the paper can also be applied to the Chinese National Standard (CNS) A4 specification (210X 297 mm). -10- 1251608 A7 B7 Ministry of Economic Affairs Intellectual Property Bureau employee consumption cooperative printing 5, invention description (8) 0 As a melt viscosity stabilizer, any known agent may be used, but the improvement in physical properties such as color tone, heat resistance, and boiling water resistance of the polymer can be maximized. It is preferred to use an organic sulfonate, an organic extended acid ester, an organic sulfonate anhydrate, and a sulfonic acid compound such as an organic sulfonic acid betaine. Further, it is preferably a user of a sulfonic acid scale salt and/or a sulfonic acid ammonium salt. In particular, tetrabutylammonium laurylbenzenesulfonate (hereinafter referred to as D B S P ), tetrabutylammonium p-toluenesulfonate and the like are preferred examples. In the present invention, the amount of the melt viscosity stabilizer used is selected from the group consisting of alkali metals and alkaline earth metals used as catalysts, and 化学 5 to 20 times the chemical equivalent. In the polycarbonate, the terminal hydroxyl group concentration is 5 to 100 equivalents of 1 ton of polymer, preferably 5 to 80 equivalents, more preferably 5 to 60 equivalents, especially 5 to 5 0 equivalent is optimal. This amount is judged to be a good controllability of mold release by the adhesion of the surface of the mold to the surface of the molded article by containing a terminal hydroxyl group. The less the terminal hydroxyl group is, the better the mold release property is. However, when the terminal hydroxyl group concentration is reduced to 5 equivalents or less, the degree of reproducibility cannot be further improved. Further, when the concentration of the terminal hydroxyl group of 100 or more equivalents is introduced, it is presumed that an oxidation reaction is likely to occur during molding, and incineration of the molded article occurs, which is disadvantageous for the purpose of the present invention. The polycarbonate composition produced by the injection molding of the present invention can be produced by any method, but the cost surface of the engineering and raw materials can be completed without using a polymerization solvent containing a halogen-containing solvent, and the like. It can be completed by the harmful compounds such as phosgene of carbonate-forming compounds. It can be melted (please read the notes on the back and fill out this page).

The reaction temperature varies depending on the boiling point of the product, etc., and the alcohol or phenol which is produced by the removal reaction is usually in the range of from 1 2 〜 to 3,500 °C. When the polycarbonate is produced by the melt method in the first step, the temperature is gradually increased in the temperature range of 1 800 to 2200 ° C in the initial stage of the reaction, and the pressure in the reaction system is gradually reduced to 10 0 1 〇〇 mm H . g 'only, in the manufacture of the polycarbonate of the present invention, the specific component content of the component of the contact surface of the mold polymer attached to the continuous injection molding is in a specific range, especially in the initial stage of the reaction from 1 800 to 2 2 0 ° In the temperature range of C, the temperature is gradually increased, and the reaction is carried out in the range of 40 to 150 mm H g and the internal pressure is higher than the normal pressure, and the reaction time is longer than usual.
