Description

1227247 A7 _____B7 V. Description of the invention (彳) Technical field (please read the notes on the back before filling out this page) This invention relates to aromatic polycarbonate, its composition and moldings, and more specifically, it applies to Aromatic polycarbonates and molded articles having the aforementioned characteristics are formed into molded articles with low molding strain and good durability and stability. In terms of moldability, mechanical strength, and transparent point, the current technology, because polycarbonate resin is superior to other resins, can be used for recording or reproducing information such as audio discs, laser discs, optical discs or magneto-optical discs using laser light Materials such as transparent substrates for recording media, or transparent sheets, lenses, etc. However, this excellent polycarbonate resin property is based on the non-crystalline nature of polycarbonate. When polycarbonate crystalline particles are mixed, the breaking strength of the molded product will be reduced, and the mechanical properties shown by the elongation will be lost. One of the characteristics of carbonate is its ductility and reduced impact strength. It also internally deforms optically, strains external images and impairs the perspective characteristics, and it is easy to hydrolyze under low temperature and high temperature to reduce low molecular weight. The polycarbonate resin printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is made of aromatic dihydroxy compounds and carbonate-forming precursors. Known manufacturing methods such as driving carbonate-forming Surface polycondensation method for direct reaction of phosgene, or melt polycondensation method for transesterification with carbonic acid diester under heating and reduced pressure. Among them, the melt polycondensation method has the advantages of being able to manufacture polycarbonate more cheaply than the surface polycondensation method. However, when the polycarbonate produced by the melt polycondensation method is used in molded articles, sheets or optical disc substrates, the paper size will be reduced due to the inclusion of crystalline particles in the paper. The Chinese standard (CNS) A4 specification (210X297 mm) is applicable. ）, -4-1227247 A7 ___B7 5. Description of the invention (2) (Please read the precautions on the back before filling this page) Low mechanical properties such as low elongation at break, so there is no extension of the characteristics of polycarbonate resin In addition, it will reduce the impact strength and damage the see-through characteristics, and the surface of the crystal particles under high temperature and high humidity tends to hydrolyze and tend to reduce the molecular weight. Even if a molded article is formed from a carbonate ester containing crystal particles that cannot be visually inspected, the mechanical properties tend to decrease. Japanese Unexamined Patent Publication No. 2 1 3 5 2 2 2 reviews foreign matter in polycarbonate. In this bulletin, the amount of gelation product remaining in the filter when filtering a dichloromethane solution of a polycarbonate with a 20 // m-sized filter was specified. It is also described that when the polycarbonate obtained by the surface polycondensation method is thermally decomposed during molding, a gel of up to 1 cm will be produced. When the amount of the gel is large, the polycarbonate sheet will be relatively small. Multiple refraction is abnormal. Compared with the surface polycondensation method, there are more types of polycarbonate foreign matter obtained by melting and condensing the thermal history with higher temperature and longer time. However, there is no information on the specific foreign body content of various foreign bodies that affect the polymer quality. The polycarbonate resin printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs contains an X-ray refraction diagram with a melting point of 3 1 0 t or more and a long diameter of 50; m or less (hardly containing coarse particles exceeding 50 // m, When it is difficult to remove fine crystalline particles with a general filter), the content of the fine crystalline particles is melt-condensation under the transesterification method and the transesterification catalyst is active. In addition, most of the other reactants have a temperature history lower than the specific temperature specified by the molecular weight. However, there is no technology or transparent resin application to produce molded articles with good mechanical properties by reducing the fine crystalline particles, which can improve the long-term reliability of optical disc substrates. -5- This paper standard applies to Chinese national standards (CNS ) A4 specification (210X297 mm) 1227247 A7 B7 V. Description of the invention (3) The invention was not disclosed in view of this. After intensive review of the problem, the present invention found that the polycarbonate obtained by melt polycondensation with a transesterification catalyst exists In terms of esters, the reason for reducing the mechanical properties such as the breaking elongation of the molded product is that it can be captured by a 3 // m filter and has a fine crystalline substance with an X-ray refraction pattern. Among them, the focus is on fine crystalline particles that are insoluble in dichloromethane solvents and have a melting point of 3]-° or more. In the following, if there is no need to specifically explain the above-mentioned fine crystalline particles having an X-ray refraction pattern, they are briefly described as fine crystals or fine crystalline particles. Because the fine crystalline particles are insoluble in dichloromethane and have a melting point of 3 1 0 ° C or higher, they are different from the current phosgene method that is easily soluble in dichloromethane and has a melting point of 2 40 ° C, or a melting point of 2 8 0 Crystal powders obtained by solid phase polymerization at ° C. Because the content of fine crystalline particles in the polycarbonate resin is 50 particles / kg or less, the mechanical property represented by the breaking strength and elongation of the molded product formed by the resin can be improved to a state of ductile failure. To obtain a molded article with high impact strength, one of the characteristics of polycarbonate. In addition, it can significantly reduce the number of deformation points contained in substrates, sheets, and lenses in transparent molded products and "effectively control deterioration such as molecular weight reduction under high temperature and high humidity. Therefore, for example," if the optical disc can be maintained at a high level for a long time Reliability, or other molded parts of optical parts to obtain its good transparency and transparency. The method of measuring the content of fine crystalline particles captured by a nominal pore size / m filter and having an X-ray refraction pattern is to dissolve 1 kg of polycarbonate resin in 20% in a sterile room with a level of 1,000 or more for eliminating interference. < The size of this paper is applicable to Chinese National Standards (CNS) M specifications (210X 297 mm) (Please read the precautions on the back before filling out this page) Order printed by the Intellectual Property Bureau of the Ministry of Economic Affairs Consumer Cooperatives 1227247 A7 B7 5 (4) Description of the invention (4) After methane filtering with a 3 // m Millipore filter under pressure, the number of fine crystalline particles on the filter was calculated by observing at 100 times under a polarizing microscope.

The present invention is the mechanical properties shown by the breaking elongation of a molded product made of polycarbonate and the transparent sheet, lens, or optical product of an optical molded product.

Brief Description of Drawings Fig. 1 is an X-ray refraction pattern of fine crystalline particles. Fig. 2 is a graph showing the relationship between the viscosity average molecular weight Mη of the aromatic polycarbonate and the minimum temperature (Tc) at which fine crystalline particles are not formed. The preferred embodiment of the invention firstly explains the above characteristics (f) of the aromatic polycarbonate of the present invention. Among the polycarbonate resins printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs, the polycarbonate resin has an X-ray refraction pattern and a nominal aperture of 3 // When the content of fine crystalline particles trapped by the filter (the following size is 3 // m or more) exceeds 50 particles / kg, for example, the breaking and elongation of the molded product indicating brittle failure of the molded product formed by the resin will be reduced. In addition, when the disc substrate is formed, the particles and the optical strain induced by the particles in the information recording medium using the substrate will become the cause of the error, which will reduce the reliability of the disc substrate. The fine crystalline particles can be specified as follows: the refraction angle in the X-ray refraction chart, such as the refraction angle, and the paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) 1227247 A7 ____B7 _ V. Description of the invention (7) (2θ) ΐ7 · 2 ° ± 0.3 ° with main peak. (Please read the precautions on the back before filling in this page) The content of fine crystalline particles is preferably 50 particles / kg or less, more preferably 30 particles / kg or less, and more preferably 10 particles / kg or less. When the stomach content is reduced to this range, the mechanical properties of the molded product and the reliability of the optical medium substrate can be improved. In addition, the content of the fine crystalline particles, which is insoluble in a dichloromethane solvent and has a melting point of 3 110 ° C or higher, is preferably reduced to 40 pieces / kg or less, and 30 pieces / kg or less is 隹When it is particularly preferably 10 pieces / kg or less, the mechanical properties of the molded product and the reliability of the optical medium substrate can be improved. When polycarbonate is produced by the melt polymerization method, in order to reduce the content of organic and inorganic foreign substances contained in fine crystalline particles, a filter can be generally used to remove it. However, polycarbonate resin has a high melt viscosity. The initial pressure needs to be increased, and the continuous filtration pressure needs to be raised to the next highest when continuing to filter. In addition, if the filtration pressure exceeds 2000 atmosphere, the filter needs to be exchanged. 0 When the printing industry operation of the consumer cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is printed, the operation must be interrupted in order to exchange the filter. Therefore, the polycarbonate quality may be uneven before and after. Big problem. Furthermore, in order to remove the fine crystalline particles, a high-efficiency filter 埘 is used, and polymer flow deviations occur in the filter box, and it is easy to cause side reactions such as deviations, hue changes, and cross-linking within the filter time. An effective method for reducing the content of fine crystalline particles having an X-ray refraction pattern and a melting point of 3 1 0 t or more when manufacturing polycarbonate by melt polycondensation method is to use, for example, when melt polycondensation and the molecular weight of the reaction mixture is set to a specific range The temperature specified by the average molecular weight without lowering the temperature of the reaction mixture. The size of this paper applies the Chinese National Standard (CNS) A4 (210X 297 mm) -10- 1227247 A7 B7 V. Description of the invention (8) and the overall polycarbonate The temperature in the low-temperature part of the polymerization device in direct contact is not lower than a specific temperature specified by the average molecular weight. (Please read the notes on the back before filling this page.) Although there are various proposals for high-melt viscosity polycarbonate polymerization devices for melt polymerization, any type of polymerization device is focused on having good stirring efficiency and high polymerization speed. However, most of these high-viscosity polymerization devices have internal temperature differences, and the temperature difference between the low temperature part and the high temperature part can reach 20 ° C to 50 °. . . Since the temperature in the low-temperature portion of the polymerization apparatus is maintained above the minimum temperature specified by the average molecular weight of the reaction mixture, the number of the above-mentioned finely crystalline particles having an X-ray refraction pattern and a melting point of 3 10 ° C or more can be greatly reduced. The graph with the viscosity average molecular weight of the reaction mixture as M η and the above minimum temperature as T c, with T c (° C) as the vertical axis and M η as the horizontal axis, M η is 3, 0 0 0 In the domains up to 18,000, the points (Tc, Mn) = (220, 4, 00 0), (234, 4, 810), (2 4 4, 6, 510), (Ministry of Economic Affairs) Printed by the Intellectual Property Bureau's Consumer Cooperatives 2 4 5, 7, 4 0 0), (2 4 4, 9, 2 1 0), (236, 12, 050), (2 26, 17,000) dot links · The resulting sliding curve (Figure 2). In order to reduce the content of fine crystalline particles, it is important that the temperature T c of the low-temperature part in the reaction system during the polymerization is not in the range between the above curve and the horizontal axis, and the lowest temperature from the low polymerization degree to the middle polymerization degree is located in this range. The curve is better. The upper limit of the minimum temperature during polymerization can be appropriately selected from the general polymerization temperature. However, when the polymerization temperature is high, the low-polymerization area may be volatile monomers. 210 parent 297 mm) ~ " 1227247 A7 ____B7 _ V. Description of the invention (9) (Please read the precautions on the back before filling this page) and destroy the Mohr equilibrium, and there will be side reactions at high polymerization, Therefore, the upper limit temperature is preferably 270 ° C when Mn < 6,000, 3 10 ° C when 6,000 S Mn $ 10,000, and 3 3 0 when Mn > 10,000. . . When the viscosity average molecular weight is 3,000 to 18,000, once fine crystalline particles are formed, the fine crystalline particles will rapidly increase the melting point due to the heat treatment of the reaction temperature, and the melting point will rise to the extent that it cannot be melted in the general melt polymerization temperature range. . Although it is easy to crystallize the reaction mixture when the viscosity average molecular weight is low, when the viscosity average molecular weight is less than 3,000, the reaction temperature of the general melt polymerization is still very high at the melting point of the relatively fine crystalline particles, so there is no reaction mixture. The problem of crystallization to produce fine crystalline particles. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs. When the viscosity average molecular weight exceeds 18,000, in order to ensure the polymerization rate, when the polymerization reaction is performed at more than 2 5 5 t, the crystallization speed of the polycarbonate reaction mixture can be reduced. It can reduce the problem of crystallization even when exposed to a low temperature, that is, the reaction mixture is low temperature. However, in general molding, fine crystalline particles are produced. That is, the fluidity of the polymer retained in the processing apparatus causes the content of bisphenol A in the polycarbonate to promote the production of fine crystalline particles. Therefore, in order to suppress the formation of fine crystalline particles during the molding process, the content of bisphenol A can be suppressed to 10 to 50 p p m, and further preferably 10 to 40 ppm, particularly preferably 10 to 30 ppm. When the content of bisphenol A is reduced to 10 p pm or less, the effect of suppressing the generation of fine crystalline particles is reduced. In order to achieve the content of bisphenol A, it can be used in the final stage of the polycondensation reaction, that is, after adding the melt viscosity stabilizer, for a short time, the paper size can be adjusted to the Chinese National Standard (CNS) A4 (210X29 * 7mm)- 12- 1227247 A7 B7 V. Description of the invention (10) (Please read the precautions on the back before filling in this page) Vacuum treatment, for example, a high vacuum below 13 · 3Pa (0 · 1 mmHg) for 30 minutes is better, more A high vacuum treatment of 1 3 to 3 Pa to 6 7 Pa (0 to 1 to 0.05 mmHg) is preferably 1 to 20 minutes. Fine crystalline particles with an X-ray refraction pattern and a melting point of 3 1 0 ° C, which are generated from a reaction mixture with an average molecular weight of 3,000 to 18,000, can be molded and processed after polymerization. When the polycarbonate processing temperature is increased to an equilibrium melting point of 3 2 7 ° C or more, it is removed by melting. However, when this method is used to form a molded article containing fine crystalline particles, it has a problem that the fracture elongation at the bottom of a molded article formed of a material which is relatively free of fine crystalline particles is low. When the aromatic polycarbonate of the present invention is (g) made into a dichloromethane solution, the long diameter of light emitted under the irradiation of ultraviolet rays with a wavelength of 3 0 8 nm captured by a filter with a nominal pore size of 10 # m 1 0 // The particle content of m or less is preferably 100 particles / kg or less of the polymer. When the content of the above light-emitting particles in the aromatic polycarbonate printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is lower than the above value, the mechanical properties such as the impact strength and elongation of the molded product and the long-term temperature and humidity can be further reduced. The degree of physical properties, or to prevent the substrate, transparent sheet, lens, optical disc substrate substrate from flowing alignment abnormality, refractive index difference and 1¾ temperature and high humidity conditions to generate water decomposition and reduce molecular weight, impact strength control to a degree The smallest range. In aromatic polycarbonates, when the content of substances with a long diameter of 1 0 0 // m that emits light under ultraviolet light at a wavelength of 380 nm exceeds 100 pieces / kg, for example, a molded article made of the resin may be reduced. -13- The paper size is in accordance with Chinese National Standards (CNS) A4 specifications (210X297 mm) 1227247 A7 B7 V. Description of the invention (彳 彳) Mechanical properties such as degree and elongation are high and long-term. Under wet conditions, the degree of mechanical and physical properties will increase, and the transparent sheet, lens, and optical disc substrate will have abnormal flow alignment points and refractive index differences. The content of the particles is preferably 80 particles / k g or less, and more preferably 5 q particles / k g or less. Reducing the content can further enhance the reliability of the optical media substrate. When a polycarbonate is produced by the melt polymerization method, the amount of light-emitting particles as described above can be reduced by the following method. i) Reduce the polymerization temperature, and reduce the temperature difference between the overall polycarbonate temperature and the heating part in the polymerization device; Π) As previously proposed by the inventors, the surface of the device of the polycarbonate polymerization device is covered with an inactive oxide layer Xun) Use high-purity raw materials, etc. to reduce the content of metal impurities in polycarbonate. There are various proposals for a polymerization device for melt polymerization of high-melt polycarbonate, and the polymerization device is focused on having good stirring efficiency and increasing the polymerization speed. However, the high-viscosity polymerization device may cause severe shearing due to high-efficiency stirring between the stirring wings or between the stirring wings and the main body of the polymerization device. Therefore, compared with the whole polycarbonate, the high temperature of the cut part can reach above 100 ° C. It is preferable to make the temperature of the sheared portion low, so that the overall temperature of the polycarbonate is as low as possible. For example, reducing the general polymerization temperature from 2 50 to 3 5 0 to 2 50 to 3 3 0 t: and preferably from 2 50 to 3 0 0 ° C, particularly preferably from 2 50 to 2 8 0 ° C. . Reduced shearing when lowering the polymerization temperature This paper applies Chinese National Standard (CNS) A4 specifications (210X297 mm) (Please read the precautions on the back before filling out this page) System 1227247 A7 A7 B7 V. Description of the invention (12) (Please read the precautions on the back before filling this page) It is better to have some heat. In addition, it is preferable to control the stirring speed as a way to reduce the heat generated by the shearing portion. That is, when producing a polycarbonate, when the viscosity average molecular weight reaches at least 8,000 and its higher resin melt viscosity stage, the temperature of the sheared portion is checked and the stirring speed is controlled. Before using the melt viscosity stabilizer to deactivate the transesterification catalyst, it is better to avoid the polycarbonate from contacting the high-temperature metal surface above 350 ° C, more preferably to avoid the high temperature above 3 3 0 t, especially to avoid 3 2 High temperature above 0 ° C. In addition, it is preferable that the polycarbonate is not in contact with the surface of such a high temperature active metal. Metal surfaces can easily cause other side reactions such as decomposition of polycarbonate under high temperature conditions. A preferred method of deactivating a metal active surface is, for example, forming an oxide film on the metal active surface. The reason for the generation of most of the luminous objects in the shearing heating domain under the irradiation of 38 nm light is that the metal surface or the metal ion mixed into the polycarbonate act as a catalyst. Therefore, an effective method for suppressing the generation of the luminescent substance under the reaction mechanism is to cover the surface of the polymerization device with an inactive oxide layer as described above, or reduce the content of metal impurities in the polycarbonate.

The method of printing the melt polymerization method by the Employee Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs is to heat the aromatic dihydroxy compound and carbonic acid diester as described above in the presence of the above-mentioned transesterification catalyst in an atmospheric and / or reduced pressure environment. With stirring, the alcohol or aromatic monohydroxy compound formed is distilled off. The reaction temperature varies depending on the boiling point of the product, etc., but in order to remove the alcohol or aromatic monohydroxy compound produced by the reaction, it is generally 120 to 350 t, and to reduce the fine crystals in the polycarbonate. When the molecular weight of the reaction mixture exceeds 7,000, in order to prevent the temperature T c of the reaction mixture from falling and avoid direct contact with the reaction device part below T c is the key point. In addition, in order to reduce the generation of fine crystalline particles during molding, the content of bisphenol A that promotes the production of fine crystalline particles can be suppressed to 10 to 40 p P m.

Therefore, it is preferable to use a melt viscosity stabilizer after polymerization to stabilize the melt viscosity. The melt viscosity stabilizer of the present invention has the effect of deactivating all or part of the polymerization catalyst activity when manufacturing polycarbonate. The method of adding the melt viscosity stabilizer may be adding the polymer in a molten state after polymerization, or dissolving and adding after the polycarbonate is pelletized. For example, the melt viscosity stabilizer is added to a polycarbonate reaction product in a molten state in a reaction tank or an extruder, or the melt viscosity stabilizer is added to a reaction tank and granulated and polymerized through an extruder. The obtained polycarbonate is re-kneaded. The melt viscosity stabilizer used for printing by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs may be a known agent.
