Description

[Technical Field]

[0001] The present invention relates to a thermoplastic resin, particularly a polyester resin, a polyester carbonate resin, The present invention relates to a thermoplastic resin such as a polycarbonate resin, and a method for producing the same. The present invention also relates to optical lenses comprising thermoplastic resins. [Background technology]

[0002] Optical fibers used in the optical systems of various cameras, including cameras with integrated film and video cameras Optical glass or optical resin is used as the material for optical lenses. It has excellent heat resistance, transparency, dimensional stability, and chemical resistance, but the material cost is high and it is difficult to mold. This has the problem of poor workability and low productivity.

[0003] On the other hand, optical lenses made from optical resins can be mass-produced by injection molding. For example, thermoplastic resins are used in camera lenses. However, in recent years, the trend toward lighter, thinner, and smaller products has led to a demand for the development of resins with higher refractive indices. Generally, when the refractive index of an optical material is high, it is difficult to obtain a high refractive index from a lens having the same refractive index (Patent Documents 1 to 4). Since the lens element can be realized on a surface with a smaller curvature, the amount of aberration generated by this surface can be reduced. As a result, it is possible to reduce the number of lenses, reduce the sensitivity of the lenses to decentering, and This makes it possible to reduce the thickness and weight.

[0004] Generally, lenses used in camera optical systems have a high refractive index and a b value of It is required that the level is not too high and that chromatic aberration is suppressed. can be. However, thermoplastic resins with sufficiently high refractive index and low b-values ​​and optical The lens was not yet available.

[0005] Furthermore, in recent years, various electronic devices have been required to be water-resistant and heat-resistant. The "PCT test" (pressure cooker test) is an environmental test to evaluate the water resistance and heat resistance of equipment. This test is a moisture and heat resistance test, and measures the penetration of moisture into the sample. Therefore, the optical components made of optical resins used in electronic devices are evaluated. The lenses not only have a high refractive index and a low b value, but also high heat resistance and durability. It is also required to have water decomposability.

[0104] In the X-ray powder diffraction pattern recorded using Cu Kα radiation at 22 °C, M The EK solvate typically has the following three reflection peaks at 2θ values: 7.0±0. 2°, 16.8±0.2° and 23.4±0.2°; and At least three, particularly at least five, at least seven of the following 2θ values: Or all reflection peaks: 5.0±0.2°, 7.5±0.2°, 12.6±0.2°, 13.4±0.2°, 14.5±0.2°, 15.4±0.2°, 15.7±0.2°, 18.3±0.2°, 19.4±0.2°, 20.6±0.2°, 21.5±0.2°, 22.7±0.2°, 24.1±0.2°, 25.6±0.2°, 26.2±0.2°, 26.6±0.2° and 30.8±0.2°;

[0105] The MEK solvate is also characterized by an endothermic peak indicating its decomposition. K solvate was measured according to ISO 11357-3:2018 at a heating rate of 20 K / min. When analyzed by DSC, the MEK solvate typically exhibits a temperature range of 87-91 °C. It shows an endothermic peak with an onset point at 95 to 100°C, and the maximum value of the peak is in the range of 95 to 100°C. The reaction point is usually in the range of 94 to 98°C.

[0106] The MEK solvate is a high temperature MEK solvate of 6,6'-DPBHBNA containing more than 5% by weight of 6,6' from solutions of other organic solvents, especially MEK, which does not contain more than 0.5% by weight of methanol. To obtain the desired MEK solvate, the crystallization step The target 6,6'-DPBHBNA is at least 97% by weight of organic matter other than solvents. % purity. 6,6'-DPBHBNA having a purity of at least 97% by weight is It is preferably dissolved in hot MEK. Usually, a hot solution of 6,6'-DPBHBNA The temperature of the solution is at least 60°C and may be as high as reflux. The concentration of 6'-DPBHBNA usually does not exceed 50% by weight, and is usually between 10 and 40% by weight. Crystallization of MEK solvates from hot solutions is usually carried out at temperatures below 50°C, e.g., -1 This is achieved by cooling the hot solution to a temperature ranging from 0 to less than 50°C, from -5 to 40°C. Seed crystals may be added at temperatures below 50°C, for example in the range of -5 to 40°C. The amount of seed crystals is usually determined based on the amount of 6,6'-DPBHBNA to be crystallized as the MEK solvate. Based on the above, the concentration is 0.05 to 2% by weight, particularly 0.1 to 1% by weight. The time to completion depends on the concentration of 6,6'-DPBHBNA and the temperature applied. The crystallization time can vary, but is typically in the range of 4 to 24 hours. This can also be achieved by concentrating the hot solution or by a combination of concentrating and cooling. Condensation can be achieved by distilling off a portion of the MEK.

[0107] The MEK solvate crystallizes into compact crystals with low aspect ratios. The aspect ratio of the MEK solvate is usually less than 5, and even between 1 and 5. The crystal size is usually in the range of 1-300 μm. MEK solvent Crystals of the dihydrate tend not to trap significant amounts of mother liquor. The crystalline solvate of BNA with MEK has a solubility of at least 99%, and even at least 99.5%. % or more, even up to 99.7% or more, to improve the purity of 6,6'-DPBHBNA Makes the above possible.

[0108] Despite the high purity of the crystalline forms of 6,6'-DPBHBNA mentioned above, they are amorphous. It can be converted to (amorphous) Form B. Amorphous Form B is stable and remains stable even after long-term storage. Even after being broken down by grinding, it does not tend to crystallize. Amorphous Form B can be obtained by dissolving either of the crystalline forms and then rapidly cooling them. Preferably, each crystalline form is completely melted to form a clear solution. It is heated to a temperature at least 5 K above its melting point until a liquid is obtained. When a solvate is used as a starting material for the preparation, preferably any solvent The solution is preferably subjected to a vacuum of at least 5 K / min. The cooling rate is rapid, for example, at a rate of 5 to 50 K / min. is obtained as a solid amorphous (glass). This amorphous material can be used to obtain a powder, e.g. It can be crushed by grinding, etc. To prevent crystallization, ) is carried out at temperatures significantly lower than 100°C, for example in the range of 5 to 40°C. In this powder, the particles are still present as amorphous Form B.

[0109] In the X-ray powder diffraction pattern recorded using Cu Kα radiation at 22°C, the shape Form B usually exhibits reflection peaks as 2θ values ​​at multiple diffraction angles in the range of 5° to 40°. Rather, a broad halo was observed, indicating the substantial absence of a crystalline layer. will be done.

[0110] Form B also conforms to ISO 11357-3:2018 at a heating rate of 20 K / min. When analyzed by DSC using the same method, it was found that no endothermic peak was observed in the range of 80 to 200°C. Rather, under these conditions, amorphous Form B is characterized by a 105 to 150% solubility in water. It may exhibit a glass transition temperature of 125°C.

[0111] The amorphous form B of 6,6'-DPBHBNA is typically at least 99%, and even less. The purity of the above-mentioned fluorine-containing compound is at least 99.5% or more, and even 99.7% or more. This means that the total amount of impurities other than the solvent in Form B does not exceed 1% by weight. In particular, it means that the content does not exceed 0.5% by weight, and even more particularly 0.3% by weight. 2-(2-hydroxyethoxy)-2'-hydroxy-6,6'-diphenyl-1 ,1´-Binaphthalene, 2,2´-bishydroxy-6,6´-diphenyl-1,1´- Binaphthalene and 2-(2-hydroxyethoxy)-2'-(2-(2-hydroxy (ethoxy)-ethoxy)-6,6'-diphenyl-1,1'-binaphthalene The total amount of impurities selected from the above is the single 6,6'-DPBHBNA contained in the crystals of Form B. On a parts by weight basis, it is often at most 5000 ppm or less, preferably at most The maximum concentration is 4000 ppm or less, and in particular, the maximum concentration is 3000 ppm or less. In particular, the weight of each of these impurities is less than 2000 ppm at most. Based on 1 part by weight of 6,6'-DPBHBNA contained in the crystals of Form B, at most 2 000 ppm or less, and even a maximum of 1500 ppm or less, and even a maximum of Preferably, the content of the amorphous form B is 1000 ppm or less. 1-[2-(2-hydroxyethoxy)-6-phenyl-1-naphthyl]-6-phenyl If it contains amorphous 2-naphthyloxyethyl carbonate, the amount is usually Based on 1 part by weight of 6,6'-DPBHBNA contained in the crystals of Form B, ppm, and often a maximum of 1500 ppm or less.

[0112] Surprisingly, 2,2'-bis(2-hydroxyethoxy)-6,6'-diphenyl Crystallization of 6,6'-DPBHBNA from ethanol solution of 1,1'-binaphthalene It is not an ethanol solvate, but a novel polymorph of 6,6'-DPBHBNA. This gave rise to a polymorph, hereinafter referred to as Form C. Form C does not contain significant amounts of solvent and is therefore suitable for use in the present invention. It is particularly useful in the production of thermoplastic resins in the light.

[0113] Form C typically contains more than 0.1 moles of 6,6'-DPBHBNA per mole of 6,6'-DPBHBNA. The total amount of organic solvent in Form C is: It is usually less than 1% by weight, in particular at most 0.5% by weight or at most 0.1% by weight. %.

[0114] In the X-ray powder diffraction pattern recorded using Cu Kα radiation at 22°C, the shape Form C usually has the following three reflection peaks at 2θ values: 5.1±0.2°, 7 0.6±0.2° and 21.0±0.2°; and At least three, particularly at least five, at least seven of the following 2θ values: Or all reflection peaks: 8.2±0.2°, 9.2±0.2°, 10.4±0.2°, 10.8±0.2°, 11.6±0.2°, 12.8±0.2°, 13.4±0.2°, 14.5±0.2°, 15.2±0.2°, 15.6±0.2°, 16.6±0.2°, 17.4±0.2°, 17.9±0.2°, 18.5±0.2°, 19.2±0.2°, 19.9±0.2°, 20.4±0.2°, 21.8±0.2°, 22.2±0.2°, 22.6±0.2°, 13.4±0.2°, 24.0±0.2°, 25.7±0.2°, 27.3±0.2° and 27.9±0.2°;

[0115] The X-ray powder diffraction pattern of Form C is comparable to that of the toluene solvate. The pattern was almost identical to that of the 6,6'-DPBHBNA in Form C. This shows that the molecules are arranged in the same way as in the crystal lattice in the toluene solvate.

[0116] Form C is also characterized by an endothermic peak indicating its melting. DSC recorded according to ISO 11357-3:2018 with a heating rate of K / min When analyzed, Form C typically exhibits an endothermic peak with an onset in the range of 115-118°C. The maximum value of the peak is in the range of 124 to 126°C. The temperature (temperature point) is usually in the range of 120 to 122°C.

[0117] Form C is the 6,6'-DPBHB produced by the hot ethanol treatment of 6,6'-DPBHBNA. To obtain the desired Form C, the 6,6'-NA is crystallized. DPBHBNA typically has a purity of at least 97% by weight with respect to organic matter other than the solvent. 6,6'-DPBHBNA having a purity of at least 97% by weight is obtained by high-temperature ethanol It is preferable that the 6,6'-DPBHBNA solution is dissolved in a solution of 1000 kJ / L. The temperature is at least 45°C and may be as high as reflux. The concentration of BHBNA usually does not exceed 30% by weight, and is usually between 2 and 25% by weight. Crystallization of Form C from a solution is typically carried out at temperatures below 40°C, e.g., from -10 to below 40°C, e.g., - This is achieved by cooling the hot solution to a temperature in the range of 5 to 30°C. Seed crystals may be added at a temperature in the range of -5 to 30°C. The amount of seed crystals is usually 0.05 to 2% by weight based on the amount of 6,6'-DPBHBNA crystallized as Form C; In particular, it is 0.1 to 1 wt. %. The time to complete the crystallization of Form C is 6,6'-D Typically, 4-24 h is used, although this may vary depending on the concentration of PBHBNA and the temperature applied. The crystallization of Form C occurs by concentrating a hot solution or by a combination of concentration and cooling. Concentration of the solution can also be achieved by evaporating off part of the solvent. It can be done.

[0118] Form C is obtained by crystallization as a compact crystalline form with a low aspect ratio. The aspect ratio of Form C is typically less than 5 and even in the range of 1 to 4. The crystal size is usually in the range of 2-250 μm.

[0119] Form C crystals tend not to trap significant amounts of mother liquor. The crystalline form C of BHBNA is at least 99%, and even at least 99.5%. or more, and even up to at least 99.7% or more of 6,6'-DPB As mentioned above, this allows for an improvement in the purity of the HBNA. The total amount of impurities should not exceed 1% by weight, in particular 0.5% by weight, and even more particularly 0.3% by weight. In particular, in Form C, 2-(2-hydroxyethoxy)-2' -Hydroxy-6,6'-diphenyl-1,1'-binaphthalene, 2,2'-bishydro 6,6'-diphenyl-1,1'-binaphthalene and 2-(2-hydroxyethoxy) (2-(2-hydroxyethoxy)-ethoxy)-6,6'-diphenyl The total amount of impurities selected from the group consisting of 1,1'-dibenzo-1,1'-binaphthalene in the crystals of Form C is Based on 1 part by weight of the 6,6'-DPBHBNA contained, it is often at most 500 0 ppm or less, preferably at most 4000 ppm or less, in particular at most The maximum concentration is 2000 ppm or less, and even 1000 ppm or less. The weight of each of these impurities is 1 / 2 of the weight of 6,6'-DPBHBNA contained in the crystals of Form C. On a weight basis, the maximum is 2000 ppm or less, and even more so, the maximum is 1500 ppm pm or less, and preferably at most 1000 ppm. However, bis[2-[[1-[2-(2-hydroxyethoxy)-6-phenyl-1-naphthyl phenyl-6-phenyl-2-naphthyl-oxy-ethyl carbonate, The amount is usually based on 1 part by weight of 6,6'-DPBHBNA contained in the crystals of Form C.
