Description

TECHNICAL FIELD

[0001] The present application relates to a thermoplastic resin composition and the like. The present application particularly relates to a thermoplastic resin composition for optical materials, a molded body containing the thermoplastic resin composition, an additive to be added to a thermoplastic resin, a manufacturing method of a thermoplastic resin composition, and a transmittance improving method, and the like. BACKGROUND

[0002] At present, in thermoplastic resins used as optical materials, additives such as antioxidants, releasing agents, and the like are added to ensure stability at the time of processing, releasability.

[0003] For example, it is known to add an antioxidant to a resin to improve stability at the time of processing (for example, Patent Literatures 1 and 2).

[0004] However, sometimes the original resin properties are impaired due to the addition of these additives. For example, there is a problem that the transmittance in the short wavelength region, which is extremely important for thermoplastic resins as optical materials, is reduced due to the addition of additives.

[0005] A slight change in the transmittance in the short wavelength region of a thermoplastic resin as an optical material sometimes also has a large impact on a product for practical use. Therefore, although a resin composition that can maintain the original transmittance of a thermoplastic resin as an optical material after a product is manufactured is required, a resin composition that can reliably suppress changes in transmittance has not been realized.

[0107] In addition, in R1to R5of General Formula (1), preferably 2 to 4 are hydrogen atoms and 1 to 3 are alkyl groups, more preferably 3 are hydrogen atoms and 2 are alkyl groups.

[0108] In General Formula (1), R6to R9independently represent a hydrogen atom or an alkyl group having a total of 1 to 20 carbon atoms which can have a substituent.

[0109] In addition, in R6to R9of General Formula (1), preferably 1 to 3 are hydrogen atoms and 1 to 3 are alkyl groups, more preferably 2 are hydrogen atoms and 2 are alkyl groups.

R 10 is more preferably a hydrogen atom.

[0111] In General Formula (1), the carbon atom to which R 10 is bonded is a chiral carbon, but the complexing agent of General Formula (1) can be a racemate or an optically active body.

[0142] [1-4. Catalyst deactivator]

[0143] In the thermoplastic resin composition, a catalyst deactivator is preferably further contained as an additive. The catalyst deactivator deactivates a catalyst used for polymerization of the resin composition, thereby stopping the polymerization reaction. By adding the catalyst deactivator, depolymerization of the polymer contained in the resin composition can also be prevented. In addition, in order to prevent an increase in the thermal history of the resin composition due to the addition of the catalyst deactivator, the catalyst deactivator can also not be used.

[0144] As the catalyst deactivator, esters such as butyl benzoate; aromatic sulfonic acids such as p-toluenesulfonic acid; aromatic sulfonic acid esters such as butyl p-toluenesulfonate, hexyl p-toluenesulfonate; phosphoric acids such as phosphorous acid, phosphoric acid, phosphonic acid; phosphite esters such as triphenyl phosphite, monophenyl phosphite, diphenyl phosphite, diethyl phosphite, di-n-propyl phosphite, di-n-butyl phosphite, di-n-hexyl phosphite, dioctyl phosphite, mono-octyl phosphite; phosphoric acid esters such as triphenyl phosphoric acid ester, diphenyl phosphoric acid ester, monophenyl phosphoric acid ester, dibutyl phosphoric acid ester, dioctyl phosphoric acid ester, mono-octyl phosphoric acid ester; phosphonic acids such as diphenyl phosphonic acid, dioctyl phosphonic acid, dibutyl phosphonic acid; phosphonic acid esters such as diethyl phenyl phosphonic acid ester; phosphines such as triphenyl phosphine, bis(diphenylphosphino)ethane; boronic acids such as boric acid, phenyl boronic acid; aromatic sulfonic acid salts such as dodecylbenzenesulfonic acid tetrabutylphosphonium salt; organic halides such as stearoyl chloride, benzoyl chloride, p-toluenesulfonyl chloride; alkyl sulfates such as dimethyl sulfate; and organic halides such as benzyl chloride are preferably used. From the viewpoint of the effect of the deactivator, stability to the resin, and the like, dodecylbenzenesulfonic acid tetrabutylphosphonium salt, butyl p-toluenesulfonate, or p-toluenesulfonic acid is particularly preferred. These deactivators are preferably used in a range of 0.01 to 50 times the molar amount, and more preferably in a range of 0.3 to 20 times the molar amount, relative to the amount of the catalyst. When the amount of the deactivator is less than 0.01 times the molar amount relative to the amount of the catalyst, the deactivating effect becomes insufficient, and thus is not preferred. In addition, when the amount of the deactivator is more than 50 times the molar amount relative to the amount of the catalyst, the heat resistance of the resin decreases, and the molded body becomes likely to be colored, and thus is not preferred.

[0145] In the thermoplastic resin composition, the catalyst deactivator is preferably contained in an amount of 1 to 1000 parts by weight, based on the total weight of the resin composition. The content of the catalyst deactivator in the thermoplastic resin composition is more preferably 3 to 500 parts by weight, still more preferably 5 to 100 parts by weight, and particularly preferably 10 to 50 parts by weight.

[0146] The catalyst deactivator is preferably added to the thermoplastic resin composition in the form of a solution, for example, in the form of an aqueous solution. In addition, the catalyst deactivator can also be added to the thermoplastic resin composition in the form of an alcoholic solution such as a methanol solution, an ethanol solution, or the like, or in the form of a solution of an organic solvent such as a phenol solution, or the like.

[0147] [1-5. Other additives]

[0148] In addition to the above-described compounding agents, antioxidants, release agents, and catalyst deactivators, an additive can be added to the thermoplastic resin composition. For example, as the additive that can be contained in the thermoplastic resin composition, heat stabilizers, plasticizers, fillers, ultraviolet absorbers, rust preventives, dispersants, antifoaming agents, leveling agents, flame retardants, lubricants, dyes, pigments, bluing agents, nucleating agents, transparency agents, and the like can be exemplified.

[0149] The content of the additive other than the antioxidants, the release agents, and the catalyst deactivators in the thermoplastic resin composition (hereinafter, also referred to as an additional additive) is preferably 10 ppm by weight to 5.0% by weight, more preferably 100 ppm by weight to 2.0% by weight, and even more preferably 1000 ppm by weight to 1.0% by weight, but is not limited thereto.

[0236] [2. Properties of the thermoplastic resin composition]

[0237] The thermoplastic resin composition of the present application with the complexing agent can maintain the transmittance (%) at a high level compared to the thermoplastic resin composition not containing the complexing agent.

[0238] For example, the value of the transmittance (%) in the wavelength of 370 nm to 400 nm measured according to JIS K7105 of the thermoplastic resin composition is greater than or equal to 2.0 (%) than that of the comparative resin composition having the same composition except that the complexing agent is not contained. That is, when the value of the transmittance (%) in the wavelength of 370 nm to 400 nm measured according to JIS K7105 of the comparative resin composition not containing the complexing agent is compared with that of the thermoplastic resin composition of the present application, the value of the transmittance of the thermoplastic resin composition is higher, and as the difference of these values, greater than or equal to 2.0 (%) can be achieved. The value of the transmittance of the thermoplastic resin composition is preferably greater than or equal to 3.0 (%) than that of the comparative resin composition, and more preferably greater than or equal to 4.0 (%).

[0239] In addition, for example, the value of the transmittance (%) in the wavelength range of 370 to 400 nm measured in accordance with JIS K7105 is 1.1 times or more in the thermoplastic resin composition than in a comparative resin composition having the same composition except that the compounding agent is not contained. That is, when the value of the transmittance (%) in the wavelength range of 370 to 400 nm measured in accordance with JIS K7105 is compared between the comparative resin composition in which the compounding agent is not contained and the thermoplastic resin composition of the present application, the value of the transmittance (%) of the thermoplastic resin composition is higher than that of the comparative resin composition, and is 1.1 times or more. The value of the transmittance of the thermoplastic resin composition is preferably 1.3 times or more, more preferably 1.5 times or more, of the value of the transmittance of the comparative resin composition.

[0240] When an additive such as a release agent, an antioxidant, or the like is added to the thermoplastic resin composition of the present application, there is a tendency that the value of the transmittance of the resulting thermoplastic resin composition decreases. However, in the thermoplastic resin composition to which the above-mentioned compounding agent is added, the decrease in the value of the transmittance can be prevented and suppressed.

[0241] In addition, the value of the haze measured in accordance with JIS K-7361 and JIS K-7136 is lower in the thermoplastic resin composition of one embodiment than in a comparative resin composition having the same composition except that the compounding agent is not contained, and a difference of 0.03 or more in the value of the haze is confirmed. In this way, it is confirmed that the above-mentioned compounding agent also has an effect of improving the transparency of the thermoplastic resin composition.

[0242] The difference in the value of the haze of the thermoplastic resin composition from that of the comparative resin composition is preferably 0.05 or more, more preferably 0.07 or more, still more preferably 0.10 or more, and particularly preferably 0.12 or more. In addition, the thermoplastic resin composition of one embodiment has a value of the haze that is 0.15 or more lower than that of the comparative resin composition, and the thermoplastic resin composition preferably has a value of the haze that is 0.18 or more lower than that of the comparative resin composition, or a value of the haze that is 0.20 or more lower than that of the comparative resin composition.

[0243] In addition, the thermoplastic resin composition of one embodiment has a lower YI value than a comparative resin composition having the same composition as the thermoplastic resin composition except that the additive is not contained. Specifically, the YI value of the thermoplastic resin composition containing the additive described above, for example, the YI value measured in accordance with JIS K 7105, can be lower than the YI value of the thermoplastic resin composition having the same composition except that the additive is not contained, by 0.20 or more. The difference between these YI values can be, for example, 0.50 or more, 0.80 or more, 0.90 or more, 1.0 or more, or 1.1 or more.

[0244] As described above, the thermoplastic resin composition of one embodiment, which can achieve maintenance of high transmittance, improvement in hue represented by a low YI value, and the like, is suitable for use in applications such as optical materials. The thermoplastic resin composition of one embodiment is particularly suitable for use as an optical material.

[0245] Furthermore, the thermoplastic resin composition of one embodiment has high heat resistance and transparency, and can achieve an effect of reducing the amount of volatile components. In particular, the polyester resin composition of one embodiment, as described later, achieves an effect of reducing the amount of volatile components at high temperatures, and can suppress odor generated upon heating. Thus, the thermoplastic resin composition of one embodiment, particularly the polyester resin composition, is also useful as plastic for food container packaging, for example.

[0246] For example, the thermoplastic resin composition of one embodiment has the same or better effect of suppressing volatile components described later, as compared to a comparative resin composition having the same composition as the thermoplastic resin composition except that the additive is not contained. That is, the thermoplastic resin composition can suppress the amount of volatile components generated under a predetermined condition described later, such as heating at 250 °C for 5 minutes.

[0247] Specific examples of the volatile components include formaldehyde, acetaldehyde, acetone, 2,3-butanedione, acetic acid, formic acid, and the like.

[0248] [3. Method for manufacturing thermoplastic resin composition]

[0249] The method for manufacturing the thermoplastic resin composition for optical materials of one embodiment includes a step of adding the additive described above to a thermoplastic resin. By the step of adding the additive to the thermoplastic resin, the transmittance of the thermoplastic resin, particularly the value of the transmittance at a low wavelength, can be favorably maintained as compared to a thermoplastic resin to which the additive is not added.

[0250] [4. Method for improving transmittance of thermoplastic resin composition]

[0251] The method for improving the transmittance of the thermoplastic resin composition for optical materials of the present application includes a step of adding the above-described complexing agent to the thermoplastic resin. By the step of adding the complexing agent to the thermoplastic resin, the transmittance of the thermoplastic resin can be improved, and in particular, the value of the transmittance at a low wavelength can be improved. In particular, in the thermoplastic resin composition further added with the complexing agent, the value of the transmittance can be improved compared to the thermoplastic resin added with an additive other than the complexing agent.

[0252] [5. Method for reducing haze of thermoplastic resin composition]

[0253] The method for reducing the haze of the thermoplastic resin composition for optical materials of the present application includes a step of adding the above-described complexing agent to the thermoplastic resin. By the step of adding the complexing agent to the thermoplastic resin, the haze value of the thermoplastic resin can be reduced, and in particular, the haze value measured according to JIS K-7361 and JIS K-7136 can be reduced. That is, the haze value of the thermoplastic resin composition is smaller than the haze value of a comparative resin composition having the same composition as the thermoplastic resin composition except that the complexing agent is not contained, and the difference between these haze values is, for example, 0.03 or more, 0.05 or more, 0.07 or more, 0.10 or more, 0.12 or more, 0.15 or more, 0.18 or more, 0.20 or more, and can also be 0.30 or more, 0.40 or more.

[0254] [6. Molded body]

[0255] The thermoplastic resin composition of the present application can be used for extrusion molding, blow molding, injection molding, and the like.

[0256] As the obtained molded product, extrusion molded products, hollow molded products, precision parts, and thin-walled injection molded products can be listed.

[0257] The thermoplastic resin composition of the present application can maintain a good value of transmittance. Therefore, the thermoplastic resin composition of the present application is particularly suitable as an optical material. As a molded body manufactured using such a thermoplastic resin composition, optical lenses, optical films, transparent conductive substrates used for liquid crystal displays, organic EL displays, solar cells, and the like, optical discs, liquid crystal panels, optical cards, films such as sheets, phase difference films, optical fibers, connectors, vapor-deposited plastic mirrors, displays, touch panels, and the like can be listed. These optical molded bodies have high transmittance even if they contain additives added for respective uses.

[0259] As the molded article obtained from the thermoplastic resin composition of the present application, particularly preferable can be listed the following articles which require high heat resistance and high transparency. That is, headlamp lenses, instrument panels, sunroofs, and the like for vehicles, and substitutes for glass windows or outer panel components; various films, light guide plates, optical disc substrates, housings of electronic equipment such as liquid crystal displays and the like, and the like.

[0260] Further, even if the molded article which does not require the excellent transparency of the thermoplastic resin composition of the present application so much, since the raw material resin composition is highly transparent, the advantage that the coloring degree is easily controlled using a colorant such as a pigment, a dye, and the like is also confirmed.

[0261] Further, on the surface of the optical molded body, a coating layer such as an antireflection layer or a hard coat layer can also be provided as necessary. The antireflection layer can be either single layer or multiple layers, and can be either organic or inorganic, and is preferably inorganic.

[0262] [6-1. Optical lens]

[0263] The optical lens manufactured using the thermoplastic resin composition of the present application not only has excellent characteristics in transmittance, but also has a high refractive index, a low Abbe number, and high heat and humidity resistance, and thus can be used in telescopes, binoculars, television projectors, and the like, which are currently using expensive high-refractive glass lenses, and is very useful. As necessary, it is preferable to use in the form of an aspherical lens. Since the aspherical lens can substantially bring the spherical aberration to zero using one lens, it is not necessary to combine a plurality of spherical lenses to eliminate the spherical aberration, and thus can achieve weight reduction and reduction of production cost. Therefore, the aspherical lens is very useful in optical lenses, particularly as a camera lens.

[0264] The optical lens can be molded by any method such as injection molding, compression molding, injection compression molding, etc. With the present application, a high refractive index, low birefringence aspherical lens that is difficult to process with a glass lens in terms of technology can be obtained more easily.

[0265] In order to avoid foreign matter from being mixed into the optical lens as much as possible, the molding environment also needs to be a low-dust environment, preferably a Class 6 or less, more preferably a Class 5 or less.

[0266] The optical lens manufactured using the thermoplastic resin composition of the present application can be obtained by injection molding the polycarbonate copolymer of the present application described above into a lens shape using an injection molding machine or an injection compression molding machine. The molding conditions for injection molding are not particularly limited, and the molding temperature is preferably 180 to 280°C.

[0267] In order to avoid foreign matter from being mixed into the optical lens as much as possible, the molding environment also needs to be a low-dust environment, preferably a Class 1000 or less, more preferably a Class 100 or less.

[0268] The optical lens containing the thermoplastic resin composition of the present application is suitably used in the form of an aspherical lens as needed. Since an aspherical lens can substantially achieve zero spherical aberration with one lens, it is not necessary to combine multiple spherical lenses to eliminate spherical aberration, and weight reduction and reduction of production costs can be achieved. Therefore, aspherical lenses are particularly useful in optical lenses, especially as camera lenses. The astigmatism of the aspherical lens is preferably 0 to 15 mλ, more preferably 0 to 10 mλ.

A coating layer such as an antireflection layer or a hard coat layer can also be provided on the surface of the optical lens of the present application as needed.

Specific examples include oxides or fluorides of silicon oxide, aluminum oxide, zirconium oxide, titanium oxide, cerium oxide, magnesium oxide, magnesium fluoride, etc. Of these, silicon oxide, zirconium oxide are more preferred, and a combination of silicon oxide and zirconium oxide is even more preferred. In addition, the antireflection layer can be a combination of single-layer / multi-layer, and the combination of their components, thickness, etc. are not particularly limited, and is preferably 2 layers or 3 layers, and is particularly preferably 3 layers. In addition, as a whole of the antireflection layer, it is preferably formed to be 0.00017 to 3.3% of the thickness of the optical lens, and specifically can be formed to be 0.05 to 3 μm, and is particularly preferably formed to be 1 to 2 μm in thickness.

[0270] [6-2. Optical film]

[0271] The optical film manufactured using the thermoplastic resin composition of the present application is excellent in transparency and heat resistance, and is thus suitable for use in a film for liquid crystal substrate, an optical memory card, or the like.

[0272] In order to avoid as much as possible the mixing of foreign matter into the optical film, the molding environment is of course required to be a low-dust environment, and is preferably a Class 6 or less, and more preferably a Class 5 or less.

[0384] [Synthesis of polyester resins (PEs-1 and PEs-2)]

[0385] A 30L polyester manufacturing unit, equipped with a packed column distillation column, a partial condenser, a total condenser, a cold trap, a stirrer, a heating device, and a nitrogen inlet pipe, was introduced with the raw material monomers listed in Table 5 below. Tetra-n-butoxytitanium and potassium acetate (0.005 mol%) were added relative to the dicarboxylic acid composition. The mixture was heated to 225°C under a nitrogen atmosphere to carry out a transesterification reaction. After the conversion rate of the dicarboxylic acid composition reached over 90%, germanium dioxide (0.025 mol%) and triethyl phosphate (0.05 mol%) were added relative to the dicarboxylic acid composition. The temperature was gradually increased and the pressure reduced, ultimately undergoing polycondensation at 280°C and below 0.1 kPa. The reaction was terminated when a suitable melt viscosity was reached, synthesizing polyester resins PEs-1 and PEs-2, respectively.
