Description

[Technical Field]

[0001] This invention relates to thermoplastic resin compositions, etc. In particular, this invention relates to thermoplastic resin compositions suitable for optical materials, molded articles containing thermoplastic resin compositions, methods for manufacturing thermoplastic resin compositions, methods for improving transmittance, etc. [Previous Technology]

[0002] Conventionally, in thermoplastic resins, additives such as antioxidants or release agents are added to ensure stability or release properties during processing. For example, it is known that adding antioxidants to resins improves stability during processing (e.g., Patent Documents 1 and 2). However, the addition of such additives can sometimes impair the properties of the resin itself. For example, in thermoplastic resins used as optical materials, there is still a problem that the addition of additives can lead to a decrease in transmittance in the extremely important short-wavelength region.

[0003] Even slight variations in the short-wavelength transmittance of thermoplastic resins, used as optical materials, can have a significant impact on commercially viable products. Therefore, there is a demand for resin compositions that maintain the inherent transmittance of thermoplastic resins as optical materials after product manufacturing, but a solution that reliably suppresses transmittance variations has not yet been achieved.

In the general formula (10) above, R 31 is hydrogen or methyl. R 32 is a hydrocarbon group having 1 to 18 carbon atoms, and may also have substituents selected from hydroxyl and alkoxy groups. Examples of R 32 include alkyl groups such as methyl, ethyl, butyl, lauryl, stearyl, cyclohexyl, and isoborneol; hydroxyalkyl groups such as 2-hydroxyethyl, 2-hydroxypropyl, and 2-hydroxy-2-methylpropyl; alkoxyalkyl groups such as 2-methoxyethyl, 2-ethoxyethyl, and 2-phenoxyethyl; and aryl groups such as benzyl and phenyl. It can also be an organic group formed by combining one or more of these groups. The carbon number of the alkoxy group is preferably 1 to 10, and more preferably 1 to 6. Examples of alkoxy groups include methoxy, ethoxy, and phenoxy. When a plurality of (meth)acrylate constituent units (constituent unit (a)) are present in the acrylic resin, the plurality of R 31 and R 32 can be the same or different. Among these, the preferred unit is a (meth)acrylate unit in which R 31 is methyl and R 32 is methyl and / or ethyl, and the more preferred unit is a methacrylate unit in which R 31 is methyl and R 32 is methyl.

[0082] The constituent unit (b) is derived from an aliphatic ethylene compound. In the general formula (11) above, R 33 is hydrogen or methyl. Also, R 34 is cyclohexyl or cyclohexyl having a substituent selected from hydrocarbon groups, hydroxyl groups, alkoxy groups, and halogen atoms with 1 to 4 carbon atoms. Specific examples of hydrocarbon groups as substituents include alkyl groups such as methyl, ethyl, propyl, and butyl. The number of carbon atoms of the alkoxy group of the substituent is preferably 1 to 10, and more preferably 1 to 6. Specific examples of alkoxy groups include methoxy, ethoxy, and phenoxy. The number of halogen atoms as substituents includes fluorine, chlorine, and bromine atoms, especially chlorine and bromine atoms. When there are multiple constituent units (b) in the acrylic resin, the multiple R 33 and R 34 may be the same or different. Among these, the preferred embodiment is that R 33 is hydrogen or methyl, and R 34 is a cyclohexyl aliphatic ethylene unit; even more preferred is that R 33 is hydrogen, and R 34 is a cyclohexyl aliphatic ethylene unit.

[0083] The aforementioned acrylic resin, which can be used in thermoplastic resins, preferably mainly comprises constituent unit (a) and constituent unit (b). The total percentage of the aforementioned constituent unit (a) and constituent unit (b) relative to the total constituent units of the acrylic resin is, for example, 85-100 mol%, preferably 90-100 mol%, more preferably 95-100 mol%, and even more preferably 98-100 mol%. Furthermore, the percentage of constituent unit (a) relative to the total constituent units of the acrylic resin is, for example, 55-80 mol%, preferably 56-79 mol%, more preferably 57-78 mol%, and even more preferably 58-77 mol%. Furthermore, the percentage of constituent unit (b) relative to the total constituent units of the acrylic resin is, for example, 10-45 mol%, preferably 11-44 mol%, more preferably 12-43 mol%, and even more preferably 13-42 mol%. If the proportion of constituent units (b) relative to the total constituent units of acrylic resin is less than 10%, the acrylic resin will have reduced heat resistance or reduced dimensional stability in high humidity environments, which will be undesirable.

[0084] Without impairing optical properties, acrylic resins may also contain constituent units other than constituent units (a) and (b). Such constituent units are not particularly limited and may include, for example, constituent units derived from acrylonitrile, acrylic acid, methacrylic acid, anhydrous maleic acid, phenylmaleimide, cyclohexylmaleimide, etc.

[0085] There is no particular limitation on the manufacturing method of acrylic resin. For example, a method of copolymerizing (meth)acrylate monomer with an aromatic ethylene monomer having at least one benzene ring skeleton and then hydrogenating the benzene ring, or a method of copolymerizing (meth)acrylate monomer with an aliphatic ethylene monomer having at least one cyclohexyl ring skeleton, is suitable, with the former being particularly suitable.

[0086] As a monomer for (meth)acrylate, there is no particular limitation, and examples include methyl (meth)acrylate, ethyl (meth)acrylate, butyl (meth)acrylate, lauryl (meth)acrylate, stearyl (meth)acrylate, cyclohexyl (meth)acrylate, isoborneol (meth)acrylate, (2-hydroxyethyl) methacrylate, (2-hydroxypropyl) methacrylate, (2-hydroxy-2-methylpropyl) methacrylate, (2-methoxyethyl) methacrylate, (2-ethoxyethyl) methacrylate, (2-phenoxyethyl) methacrylate, benzyl (meth)acrylate, and phenyl (meth)acrylate. Among these, methyl methacrylate is preferred.

[0087] Specific examples of aromatic ethylene monomers include styrene, α-methylstyrene, p-hydroxystyrene, alkoxystyrene, chlorostyrene, bromostyrene, and their derivatives. Among these, styrene and α-methylstyrene are preferred.

[0088] Examples of aliphatic ethylene monomers include vinylcyclohexane, isopropenylcyclohexane, and 1-propenyl-2-methylcyclohexane. Among these, vinylcyclohexane and isopropenylcyclohexane are preferred.

[0089] The polymerization system of (meth)acrylate monomers and aromatic ethylene monomers can be manufactured using known methods, such as bulk polymerization, solution polymerization, suspension polymerization, and emulsion polymerization. Solution polymerization is carried out by continuously feeding a monomer composition containing a solvent, monomer, chain transfer agent, and polymerization initiator into a fully mixing tank and conducting continuous polymerization at 100-180°C.

[0090] Examples of solvents used in solution polymerization include hydrocarbon solvents such as toluene, dimethyl, cyclohexane, and methylcyclohexane; ester solvents such as ethyl acetate and methyl isobutyrate; ketone solvents such as acetone and methyl ethyl ketone; ether solvents such as tetrahydrofuran and dioxane; and alcohol solvents such as methanol and isopropanol.

[0091] The hydrogenation reaction following the polymerization of (meth)acrylate monomers with aromatic ethylene monomers is carried out in a suitable solvent. The solvent used in this hydrogenation reaction may be the same as or different from the aforementioned polymerization solvent. Examples include hydrocarbon solvents such as cyclohexane and methylcyclohexane; ester solvents such as ethyl acetate and methyl isobutyrate; ketone solvents such as acetone and methyl ethyl ketone; ether solvents such as tetrahydrofuran and dioxane; and alcohol solvents such as methanol and isopropanol.

[0092] There are no particular limitations on the method of hydrogenation, and well-known methods can be used. For example, it can be carried out in a batch or continuous flow manner at a hydrogen pressure of 3 to 30 MPa and a reaction temperature of 60 to 250°C. By setting the temperature above 60°C, the reaction time is not excessive, and by setting it below 250°C, the occurrence of molecular chain cleavage or hydrogenation of ester sites is minimized.

[0093] Examples of catalysts used in hydrogenation reactions include solid catalysts in which metals such as nickel, palladium, platinum, cobalt, ruthenium, and rhodium, or oxides, salts, or complexes of such metals are supported on porous carriers such as carbon, alumina, silica, silica-alumina, and diatomaceous earth.

[0094] In the hydrogenation reaction, it is preferable that more than 70% of the aromatic rings in the aromatic ethylene monomer are hydrogenated. That is, the proportion of unhydrogenated aromatic rings in the aromatic ethylene constituent unit is preferably less than 30%. If the proportion of unhydrogenated aromatic rings exceeds 30%, the transparency will decrease when used as an acrylic resin. The proportion of unhydrogenated aromatic rings is preferably less than 10%, more preferably less than 5%, and especially preferably less than 1%. However, it is not necessary to achieve 0% when considering production efficiency.

[0095] The polymerization system of (meth)acrylate monomer and aliphatic ethylene monomer can be carried out by known methods, such as those described in Japanese Patent Application Publication No. 63-3011 and Japanese Patent Application Publication No. 63-170475.

[0096] The glass transition temperature of acrylic resin is preferably in the range of 110~160℃, and more preferably 115~150℃.

[0097] Furthermore, acrylic resins can be used alone or in combination with two or more types.

[0098] The weight-average molecular weight (Mw) of the thermoplastic resin, converted from polystyrene, is, for example, 10,000 to 500,000, preferably 10,000 to 300,000, more preferably 15,000 to 100,000, and even more preferably 20,000 to 50,000. Furthermore, the above-mentioned range of the weight-average molecular weight (Mw) of polystyrene is mainly related to polycarbonate resins, polyester resins, and polyester-carbonate resins. On the other hand, the acrylic resin included in the thermoplastic resin may have a weight-average molecular weight (Mw) of polystyrene within the above-mentioned range, but 100,000 to 200,000 is preferred, and more preferably 110,000 to 170,000.

[0099] [2. Properties of the thermoplastic resin composition] Compared with thermoplastic resin compositions that do not contain admixtures, the thermoplastic resin composition of the present invention containing admixtures can maintain a high level of transmittance (%).

[0100] For example, compared with a target resin composition having the same composition without admixtures, the transmittance (%) of the thermoplastic resin composition at a wavelength of 370nm to 400nm according to JIS K7105 is greater than 1.0 (%), and preferably greater than 2.0 (%). That is, among the transmittance (%) of the target resin composition without admixtures at a wavelength of 370nm to 400nm according to JIS K7105 and the transmittance (%) of the thermoplastic resin composition of the present invention at a wavelength of 370nm to 400nm according to JIS K7105, when comparing the values ​​(%) at the same wavelength, the transmittance value of the thermoplastic resin composition is higher, and as a difference of these values, it will achieve 1.0 (%) or more, preferably 2.0 (%) or more. Preferably, the transmittance value of the thermoplastic resin composition is greater than 3.0% or more, and more preferably greater than 4.0% or more, than the transmittance value of the resin composition used in the application. Furthermore, the difference in transmittance (%) can be confirmed, for example, according to JIS K7105 at wavelengths of 380 nm to 400 nm.

[0101] Furthermore, for example, the transmittance (%) of the thermoplastic resin composition at wavelengths of 370 nm to 400 nm, according to JIS K7105, is at least 1.1 times higher than that of the target resin composition which does not contain any admixtures and has the same composition. That is, when comparing the transmittance (%) of the target resin composition which does not contain any admixtures at wavelengths of 370 nm to 400 nm according to JIS K7105 with the transmittance (%) of the thermoplastic resin composition of the present invention at wavelengths of 370 nm to 400 nm, the transmittance (%) of the thermoplastic resin composition is higher than that of the target resin composition, and is at least 1.1 times higher. It is preferable that the transmittance of the thermoplastic resin composition is at least 1.3 times that of the target resin composition, and more preferably at least 1.5 times higher.

[0102] When additives, such as release agents and antioxidants, are added to the thermoplastic resin composition of the present invention, the transmittance value of the obtained thermoplastic resin composition tends to decrease. However, by adding the above-mentioned admixtures to the thermoplastic resin composition, the decrease in transmittance value can be prevented and suppressed.

[0103] Furthermore, compared to a target resin composition having the same composition as the thermoplastic resin composition except for the absence of admixtures, the YI value of a certain type of thermoplastic resin composition is lower. Specifically, the YI value of the aforementioned thermoplastic resin composition containing admixtures, for example, according to JIS K 7105, is at least 0.20 lower than the YI value of a thermoplastic resin composition without admixtures but with the same other components. The difference in these YI values ​​is, for example, 0.50 or more, 0.80 or more, 0.90 or more, 1.0 or more, and can also be 1.1 or more. It is preferable that the YI value of the aforementioned thermoplastic resin composition containing admixtures, for example according to JIS K 7105, is less than 1.2 or more compared to the YI value of a thermoplastic resin composition without admixtures but with the same other components. Furthermore, the difference in YI values ​​is preferably 1.5 or more, 1.80 or more, or 2.0 or more, and more preferably 2.2 or more, 2.5 or more, 2.7 or more, or 3.0 or more. Also, the YI value of the thermoplastic resin composition containing the admixture shown in general formula (1), for example according to JIS K 7105, is preferably less than 0.2 compared to the YI value of a thermoplastic resin composition containing only the same amount of monomers corresponding to the admixture shown in general formula (1) (for example, compounds common to general formula (1) except that R1 to R5 in general formula (1) do not contain the cyclic structure of general formula (1-1)). Furthermore, the difference in YI values ​​is preferably 0.3 or more, 0.4 or more, or 0.5 or more, and more preferably 0.6 or more, 0.7 or more, 0.8 or more, 0.9 or more, or 1.0 or more.

[0104] As described above, the thermoplastic resin composition of the present invention, which can maintain high transmittance and improve hue as indicated by low YI values, is suitable for applications such as optical materials. The thermoplastic resin composition of the present invention is particularly suitable for use as an optical material. Furthermore, the thermoplastic resin composition of the present invention has high heat resistance and transparency, and is expected to reduce the amount of volatile components. In particular, among the polyester resin compositions of the present invention, a reduction in the amount of volatile components at high temperatures has been confirmed, as detailed later, and the generation of odors can be suppressed when heated. Therefore, the thermoplastic resin composition of the present invention, mainly a polyester resin composition, is also useful as, for example, a plastic for food container packaging. For example, compared to a target resin composition having the same composition as the thermoplastic resin composition without the presence of admixtures, a certain thermoplastic resin composition exhibits an evaporation suppression effect equal to or greater than that described later. That is, the thermoplastic resin composition system can suppress the amount of volatile components generated under the specified conditions described below when heated at 250°C for 5 minutes. Specific examples of volatile components include formaldehyde, acetaldehyde, acetone, 2,3-butanedione, acetic acid, formic acid, etc.

[0105] [3. Method for manufacturing thermoplastic resin composition] The method for manufacturing thermoplastic resin composition of the present invention includes the step of adding the above-mentioned admixture to a thermoplastic resin. By adding an admixture to the thermoplastic resin, the transmittance of the thermoplastic resin can be well maintained compared with the thermoplastic resin without the addition of an admixture, especially the transmittance value at low wavelengths.

[0106] [4. Method for Improving the Transmittance of a Thermoplastic Resin Composition] The method for improving the transmittance of a thermoplastic resin composition according to the present invention includes the step of adding the above-mentioned admixture to a thermoplastic resin. By adding the thermoplastic resin to the admixture, the transmittance of the thermoplastic resin can be improved, especially the transmittance value at low wavelengths. In particular, compared with thermoplastic resins containing additives different from the admixture, thermoplastic resin compositions with added admixtures can further improve the transmittance value.

[0107] [5. Method for Improving the Hue of a Thermoplastic Resin Composition] The method for improving the hue of a thermoplastic resin composition according to the present invention includes the step of adding the aforementioned admixture to the thermoplastic resin. By adding the admixture to the thermoplastic resin, the hue of the thermoplastic resin can be improved or enhanced, and the transparency of the thermoplastic resin can be increased. As described above, compared to the YI value of a thermoplastic resin composition that does not contain the admixture but has the same components as the others, the YI value of the thermoplastic resin composition containing the admixture is, for example, 0.2 or more lower according to JIS K 7105. Therefore, thermoplastic resin compositions containing the admixture are generally found to have a tendency to suppress yellowish tints and have excellent hue. That is, by adding an admixture to a thermoplastic resin composition, the YI value of the thermoplastic resin composition can be reduced. The difference in YI value resulting from the presence or absence of an admixture is, for example, 0.20 or more, 0.50 or more, 0.80 or more, 0.90 or more, 1.0 or more, as described above, and can also be 1.1 or more. When the above-mentioned admixture is added to a thermoplastic resin composition, for example, according to JIS K 7105, the YI value compared with the YI value of a thermoplastic resin composition without an admixture but with the same other components is preferably less than 1.2 or more. Furthermore, the difference in these YI values ​​is preferably 1.5 or more, 1.80 or more, or 2.0 or more, and more preferably 2.2 or more, 2.5 or more, 2.7 or more, or 3.0 or more. Furthermore, by adding the admixture shown in the general formula (1) to the thermoplastic resin composition, for example according to the YI value of JIS K 7105, the YI value can be preferably reduced by 0.2 or more compared to the thermoplastic resin composition that only includes the monomers corresponding to the admixture shown in the general formula (1) (for example, compounds common to the general formula (1) except that R1 to R5 in the general formula (1) do not contain the cyclic structure of the general formula (1-1)). The difference in these YI values ​​is preferably 0.3 or more, 0.4 or more, or 0.5 or more, and more preferably 0.6 or more, 0.7 or more, 0.8 or more, 0.9 or more, or 1.0 or more.

[0108] [6. Method for reducing haze of thermoplastic resin composition] Furthermore, by adding the above-mentioned admixture to the thermoplastic resin, the haze value of the thermoplastic resin can also be reduced, for example, according to the haze values ​​of JIS K-7361 and JIS K-7136. That is, the haze value of the thermoplastic resin composition tends to be smaller than the haze value of an object resin composition that has the same composition as the thermoplastic resin composition but does not contain the admixture, and the difference in such haze values ​​is, for example, 0.01 or more, 0.02 or more, 0.03 or more, 0.04 or more, or 0.05 or more.

[0109] [7. Molded Article] The thermoplastic resin composition of the present invention can be used in extrusion molding, blow molding, injection molding, etc. Examples of the obtained molded articles include extruded articles, hollow articles, injection molded articles of precision parts or thin articles. The thermoplastic resin composition of the present invention can maintain a good transmittance value. Therefore, the thermoplastic resin composition of the present invention is particularly suitable as an optical material. Examples of molded articles manufactured using this thermoplastic resin composition include transparent conductive substrates used in optical lenses, optical films, liquid crystal displays, organic EL displays, solar cells, optical discs, liquid crystal panels, optical cards, thin films, phase reversal films, optical fibers, connectors, vapor-deposited plastic reflectors, displays, touch panels, etc. Even if these optical molded articles contain additives added for various purposes, they will still have high transmittance. Specific examples of molded articles using the thermoplastic resin of this invention as an optical material and in its related fields include optical media products such as optical discs or digital image discs, mini discs, magneto-optical discs, etc.; optical communication media such as optical fibers; optical components such as headlight lenses for vehicles or lenses for cameras, etc.; alarm lamp covers, lighting lamp covers; substitutes for window glass for trams or automobiles, etc.; substitutes for window glass for homes; lighting components such as skylights or greenhouse roofs, etc.; goggles or sunglasses; lenses or frames for eyeglasses; housings for photocopiers or fax machines, OA machines such as personal computers, housings for home appliances such as televisions or microwave ovens, etc.; electronic components such as connectors or IC disks, etc. Other examples include protective equipment such as helmets, protective gear, protective masks, etc.; household items such as nursing bottles, tableware, trays, etc.; medical supplies such as artificial dialysis kits or dentures, etc.; packaging materials; notebooks, stationery, etc., etc., but are not limited to these. Molded articles derived from the thermoplastic resin composition of this invention are particularly preferred for those possessing high heat resistance and high transparency. These include automotive components such as headlight lenses, dashboards, sunroofs, and replacements or outer panel parts for glass windows; various films for liquid crystal displays, light guide plates, optical disc substrates, and housings for electronic devices such as smartphones; and building materials such as transparent sheets. Furthermore, even molded articles for which the excellent transparency of the thermoplastic resin composition of this invention is not urgently needed will find that the high transparency of the raw resin composition makes it easier to control the color intensity caused by pigments, dyes, and other colorants.

[0110] Furthermore, the surface of the optically shaped body may also be coated with a layer called an anti-reflective layer or a hard coating layer, as necessary. The anti-reflective layer may be a single layer or multiple layers, and may be organic or inorganic, but inorganic materials are preferred. Specific examples include oxides or fluorides of silicon oxide, aluminum oxide, zirconium oxide, titanium oxide, cerium oxide, magnesium oxide, and magnesium fluoride.

[0111] [7-1. Optical Lens] Optical lenses manufactured using the thermoplastic resin composition of the present invention not only have excellent transmittance characteristics, but also, due to their high refractive index, low Abbe number, and high resistance to damp heat, are extremely useful in fields such as telescopes, binoculars, and television projectors, where expensive, high-refractive-index glass lenses have been previously used. It is preferable to use them in the form of aspherical lenses if necessary. Aspherical lenses can achieve virtually zero spherical shrinkage with only one lens, thus eliminating the need for a combination of multiple spherical lenses to eliminate spherical shrinkage, thereby achieving weight reduction and lower production costs. Therefore, aspherical lenses are particularly useful as camera lenses among optical lenses. Optical lenses are formed by any method, such as injection molding, compression molding, or injection compression molding. The present invention provides a simpler way to obtain high-refractive-index, low-complexity aspherical lenses, which are technically difficult to process in glass lenses. To minimize the risk of foreign matter entering the optical lens, the forming environment must be a low-dust environment, preferably level 6 or below, and ideally level 5 or below.

[0112] Optical lenses manufactured using the thermoplastic resin composition of the present invention can be obtained by injection molding the polycarbonate copolymer of the present invention into a lens shape using an injection molding machine or an injection compression molding machine. There are no particular limitations on the injection molding conditions, but a molding temperature of 180~280°C is preferred. Furthermore, an injection pressure of 50~1700 kg / cm² is preferred. To minimize the contamination of the optical lens with foreign matter, the molding environment must be a low-dust environment, preferably with a dust level of 1000 or lower, and more preferably with a dust level of 100 or lower. Optical lenses containing the thermoplastic resin composition of the present invention are suitable for use in aspherical lens shapes when necessary. Aspherical lenses achieve virtually zero spherical shrinkage with only one lens, eliminating the need for a combination of multiple spherical lenses to remove spherical shrinkage, thus achieving weight reduction and lower production costs. Therefore, aspherical lenses are particularly useful as camera lenses among optical lenses. The astigmatism of an aspherical lens is preferably 0-15 mλ, more preferably 0-10 mλ. The thickness of the optical lens manufactured using the thermoplastic resin composition of this invention can be set in a wide range according to the application and is not particularly limited, preferably 0.01-30 mm, more preferably 0.1-15 mm. The surface of the optical lens of this invention may also be provided with a coating layer called an anti-reflective layer or a hard coating layer, as necessary. The anti-reflective layer can be a single layer or multiple layers, and can be organic or inorganic, but inorganic materials are preferred. Specific examples include oxides or fluorides of silicon oxide, aluminum oxide, zirconium oxide, titanium oxide, cerium oxide, magnesium oxide, and magnesium fluoride. Among these, silicon oxide and zirconium oxide are preferred, and a combination of silicon oxide and zirconium oxide is even more preferred. Furthermore, regarding the anti-reflective layer, there are no particular limitations on the combination of single or multiple layers, or on the combination of its components and thickness. A two-layer or three-layer structure is preferred, with a three-layer structure being particularly desirable. Also, the overall thickness of the anti-reflective layer is preferably 0.00017 to 3.3% of the thickness of the optical lens, specifically 0.05 to 3 μm, and preferably 1 to 2 μm.

[0113] [7-2. Optical Thin Film] Optical thin films manufactured using the thermoplastic resin composition of the present invention are suitable for use in liquid crystal substrate films, optical memory cards, etc., due to their excellent transparency and heat resistance. To minimize the contamination of the optical thin film with foreign matter, the forming environment must be a low-dust environment, preferably level 6 or lower, and more preferably level 5 or lower. [Example]

[0114] Hereinafter, embodiments are shown to illustrate the present invention in more detail. However, the present invention is not limited to the following embodiments, and can be implemented in any way without departing from the spirit of the present invention.

(1-1) Transmittance (spectral transmittance) [%] For Example 1, Comparative Example 1, Comparative Example 2 and Reference Example 1 described in detail later, the transmittance was measured by the following operation. After drying the particles of the thermoplastic resin composition obtained by the following method at 120°C in a hot air circulating dryer for 5 hours, a flat test piece with a width of 40 mm × length of 40 mm and a thickness of 3 mm was formed by an injection molding machine (ROBOSHOT S-2000i30A manufactured by FANUC) under the conditions of resin temperature of 260°C, mold temperature of 130°C and molding cycle of 30 seconds. According to JIS K7105, for the 3mm thick portion of the flat test piece, the transmittance (%) at wavelengths of 370nm, 380nm, and 400nm was measured using a spectrophotometer (Hitachi High Technology Co., Ltd. "U-4100"). Furthermore, in Examples 2-5, Comparative Examples 3 and 4, the resin temperature was set to 280°C, and a spectrophotometer (Nippon Denshoku Kogyo Co., Ltd. SH7000) was used. Except for wavelengths of 380nm, 390nm, and 400nm, the transmittance (%) was measured under the same conditions as in Example 1, etc.

YI rise rate (%) = (YI value after weathering test - YI value before weathering test (0 hours of radiation)) / (YI value before weathering test (0 hours of radiation)) × 100 (1-4b) Lightfastness test: The lightfastness test is performed using the same 3mm thick sample used to measure the YI value as described above. The test conditions are shown below. Apparatus: Atlas Weatherometer Ci4000 manufactured by Toyo Seiki Co., Ltd. Inner filter of lamp: Type S Outer filter of lamp: Type S Irradiance: 60W / m2 (300-400nm) Black panel temperature: 63℃ Humidity: 50% Operating conditions: 18 minutes of water spray within 120 minutes Irradiation time: 0 hours (no radiation), 400 hours, 800 hours

[0119] [Evaluation Method 2] The evaluation method in the examples of polyester resins and polyester resin compositions described in detail later is as follows.

[0120] (2-1) The ratio of diol units with a cyclic acetal skeleton to alicyclic diol units in polyester resin was calculated using 1H-NMR measurement. The measuring apparatus was a Bruker BioSpin KK Ascend™ 500. Deuterated chloroform was used as the solvent.

[0121] (2-2) The glass transition temperature (Tg) of the polyester resin was measured using a scanning calorimeter (model: DSC / TA-50WS) manufactured by Shimadzu Corporation. Approximately 10 mg of the sample was placed in an aluminum non-sealed container and measured in a nitrogen gas flow (30 ml / min) at a heating rate of 20°C / min. The temperature at which the difference between the baselines of the DSC curve before and after the glass transition only changed by 1 / 2 was taken as the glass transition temperature.

[0122] (2-3) The YI value of the particles was measured according to JIS K-7105 using the "ZE2000" manufactured by Nippon Denshoku Kogyo Co., Ltd.

[0123] (2-4) The amount of volatile components will be determined by converting the peak area of ​​low molecular weight compounds (volatile components) into a GC-MS (Head Space) value per unit weight of the sample. That is, the relative value of the peak area of ​​volatile components in other examples, etc., when the peak area of ​​volatile components in Comparative Example 5 or Comparative Example 8 described below is set to 100%, and the amount of volatile components is taken as the percentage. Specifically, it is as follows. 0.3 g of dry granules was placed in an HS vial bottle and sealed with a gap in air. After heating at 250°C for 5 minutes using a block heater, analysis was started using the Head Space-GC-MS apparatus.

The mixture was heated to 180 °C under a nitrogen atmosphere of 760 mmHg. After 30 minutes of heating, the raw materials were confirmed to be completely dissolved, and then stirred for 120 minutes under the same conditions. Subsequently, the pressure was adjusted to 200 mmHg, and the temperature was increased to 200 °C at a rate of 60 °C / hr. At this point, the by-product phenol was confirmed to begin distillation. Subsequently, the reaction was maintained at 200°C for 20 minutes. Then, the temperature was increased to 230°C at a rate of 75°C / hr, and after 10 minutes of heating, it was maintained at this temperature for 2 hours to reduce the pressure to below 1 mmHg. Afterward, the temperature was increased to 245°C at a rate of 60°C / hr, and stirring was performed for another 40 minutes. After the reaction was complete, nitrogen was introduced into the reactor to return it to atmospheric pressure. The resulting resin was then granulated and removed, yielding a thermoplastic polycarbonate resin (PC1: BPEF homopolymer resin).

[0125] <Synthesis of Thermoplastic Resin: PC2> 3634 g (15.92 moles) of 2,2-bis(4-hydroxyphenyl)propane and 30 g of bisulfite were dissolved in 40 liters of 5% (w / w) sodium hydroxide aqueous solution. 17 liters of dichloromethane were added to the solution and stirred, maintaining the temperature at 15°C, while simultaneously blowing in 2100 g (21.23 moles) of phosgene over 15 minutes. After the phosgene blowing was completed, 91.63 g (0.61 moles) of p-tert-butylphenol as a molecular weight regulator was added to the reaction solution, along with 10 liters of 5% (w / w) sodium hydroxide aqueous solution and 20 liters of dichloromethane. The mixture was stirred vigorously to emulsify the reaction solution. Subsequently, 20 mL of triethylamine was added, and the reaction was carried out by stirring at 20°C to 25°C for approximately 1 hour. After polymerization, the reaction solution was separated into an aqueous phase and an organic phase. The organic phase was neutralized with phosphoric acid and then washed with water. The obtained polymer solution was dripped into warm water maintained at 50°C. While evaporating to remove the solvent, the solids were pulverized to obtain a white powdery precipitate. The precipitate was filtered and dried at 120°C for 24 hours to obtain polymer powder (thermoplastic polycarbonate resin (PC2: bisphenol A PC resin)).

[0126] <Synthesis of Admixture (A) (Dimer)> Admixture (A) of the dimer shown in the following formula was synthesized by the following operation. 21.3 parts by mass of 2,4-di-tert-butylphenol (manufactured by Tokyo Chemical Co., Ltd.), 10.4 parts by mass of glyoxylic acid monohydrate (manufactured by Fujifilm and Wako Pure Chemical Co., Ltd.), 0.051 parts by mass of p-toluenesulfonic acid monohydrate (manufactured by Tokyo Chemical Co., Ltd.), and 40 parts by mass of 1,2-dichloroethane (manufactured by Tokyo Chemical Co., Ltd.) were measured in a flask. Next, the measured flask was placed in an oil bath at 105°C, and the distillate was removed using a Dean-Stark tube. The internal temperature was continuously heated to 86°C by adding the same amount of 1,2-dichloroethane as the amount removed. Then, the oil bath was heated to 120°C, and concentration was carried out until the remaining amount of 1,2-dichloroethane was less than 10 parts by mass. Subsequently, the reaction solution was cooled to room temperature (23°C), and 100 parts by mass of hexane and 100 parts by mass of water were added to the reaction solution and stirred. The hexane layer was then recovered, and 100 parts by mass of saturated brine was added to the reaction solution and stirred. The hexane layer was then recovered, and 1 part by mass of magnesium sulfate (manufactured by Fujifilm and Koko Pure Chemical Industries, Ltd.) was added to the reaction solution and dried for 1 hour. Next, the magnesium sulfate was filtered, and the hexane layer was concentrated and dried using an evaporator to obtain 27.0 parts by mass of a brown viscous substance (1) containing the compound shown in formula (1a). Next, 4.41 parts by mass of ethylene glycol diphenyl ether (manufactured by Tokyo Chemical Industry Co., Ltd.), 15.88 parts by mass of tin(IV) pentahydrate (manufactured by Tokyo Chemical Industry Co., Ltd.), and 81 parts by mass of 1,2-dichloroethane (manufactured by Tokyo Chemical Industry Co., Ltd.) were weighed into the brown viscous substance (1), and it was refluxed in an oil bath at 105°C for 4 hours. Next, after distilling off 40 parts by mass of 1,2-dichloroethane, the reaction solution was cooled to room temperature (23°C), and 200 parts by mass of ethyl acetate and 200 parts by mass of water were added to the reaction solution. The ethyl acetate layer was then recovered, and 200 parts by mass of saturated brine was added to the reaction solution and stirred. The ethyl acetate layer was then recovered, and the solution was purified by repeated separation using 200 parts by mass of saturated brine until the pH of the brine layer reached 6. The ethyl acetate layer was then recovered, and 1 part by mass of magnesium sulfate was added to the reaction solution and dried for 1 hour. The magnesium sulfate was then filtered through diatomaceous earth, and the ethyl acetate layer was concentrated and dried using an evaporator to obtain 21 parts by mass of a brown viscous substance (2). The obtained brown viscous substance (2) was purified by column chromatography to obtain a dimer admixture (A) as shown in formula (A). The 1H-NMR (nuclear magnetic resonance) data and their assignments for the obtained dimer admixture (A) are shown below.1HNMR (CDCl 3=7.26ppm)δ (ppm)=1.29 (18H, s), 1.43 (18H, S), 4.31 (4H, s), 4.78 (2H, s), 6.94 (4H, d), 7.04 (2H, s), 7.16 (4H, d), 7.32 (2H, s).
