Description

[Technical Field] The present invention relates to a resin composition containing a styrene-based copolymer and a norbornene-based polymer and use thereof. More specifically, the present invention relates to a styrene-based copolymer and a norbornene-based polymer which are excellent in transparency and are suitable for use in a resin composition produced by an optical film or the like, and a molded body and an optical body obtained from the resin composition. A film, an stretch film using the optical film, a polarizing plate, and a liquid crystal display device. [Prior Art] As a film such as polycarbonate or polyester used in the conventional optical film, since the photoelastic coefficient is large, the change in the micro stress is equal to the change in the phase difference due to the phase difference on the transmitted light. Further, a film such as cellulose triacetate has problems such as low heat resistance and water absorption deformation. The thermoplastic norbornene-based resin (cyclic olefin-based resin) has a high glass transition temperature and a high light transmittance, and has a small anisotropy of refractive index, so that it exhibits low birefringence and the like compared with the conventional optical film. Special features have been noted as transparent thermoplastic resins excellent in heat resistance, transparency, and optical properties. By using such a feature, for example, in the fields of optical discs, optical lenses, optical fibers, transparent plastic substrates, electronic materials such as low dielectric materials, and sealing materials such as optical semiconductor sealing, cyclic olefin resins can be used. Being reviewed. The resin of the above-mentioned cyclic olefin-based resin is a resin for an optical film, and it is a problem that the resin is improved in the past. Therefore, a film made of a hydrocarbon resin of the ring-like type-5-200838917 is used for various optical purposes. The technology used for the film has been proposed. For example, Patent Literatures 1 and 2 describe a phase difference plate using a film of a cyclic olefin resin. Further, in Patent Documents 3 to 5, a film of a cyclic olefin resin is used for a protective film of a polarizing plate. Further, Patent Document 6 describes a substrate for a liquid crystal display element formed of a film of a cyclic olefin resin. Generally, the retardation film has a function of imparting a phase difference (sub-refraction) to the transmitted light obtained by the extension alignment, and has a long wavelength which becomes a long wavelength with the wavelength of the transmitted light, and the absolute enthalpy of the phase difference (sub-refraction) of the transmitted light becomes small. Since the characteristics (positive wavelength dispersion) are in the visible light region (400 to 800 nm), it is extremely difficult to impart a specific phase difference such as a quarter wavelength to the transmitted light. In fact, the phase difference is in a wide range of wavelengths (400 to 800 nm), and it is necessary to function as a 1/4 wavelength for a reflective or transflective liquid crystal display or a disc for reading and writing. Further, in the liquid crystal projector, a phase difference of 1 / 2λ is necessary, and in the optical film formed by the conventional cyclic olefin resin, it is extremely difficult to laminate the film. In the lamination of the film, not only the steps of laminating, cutting, and adhering the film are complicated, but the thickness of the obtained optical film is also difficult to reduce, and the problem is solved. As the wavelength becomes a long wavelength, the phase difference of the transmitted light is absolutely The characteristic that 値 is also enlarged, that is, an optical film exhibiting reverse wavelength dispersion is necessary. In the optical film which exhibits the reverse wavelength dispersibility, Patent Document 7 and Patent Document 8 propose a blend of a retardation film made of a specific cellulose acetate-based resin, a polycarbonate resin, or a styrene resin. Program. However, in the film formed by the cellulose resin, there is a problem in the change of the properties of the -6 - 200838917 or the heat resistance caused by the water absorption. In the polycarbonate system, the glass transition temperature is high, and the elongation processing at a high temperature becomes necessary. Moreover, the photoelastic coefficient of the film is optically deformed due to the stress.

In addition, in a blended composition of a styrene resin and a cyclic cycloolefin resin, a solvent having a high volatility such as methylene chloride having a good film forming property at the time of film formation is phase-separated and cannot be used in almost all cases. And you must choose a specific solvent. Therefore, the drying time with a solvent is long, the productivity is extremely lowered, and it is difficult to obtain a film having a high transparency. Therefore, a resin composition capable of suppressing phase separation and easily obtaining a transparent optical film, and an optical film exhibiting reverse wavelength dispersibility and having high transparency when the resin composition is used as a main component are strongly expected.

If the molecular weight is too large, the viscosity of the solution may be too high, and the productivity or workability of the resin composition used in the present invention may be deteriorated. Further, the molecular weight distribution (Mw/Mn) of the norbornene-based polymer (B) is usually from 1 to 5 to 10, preferably from 2 to 8, more preferably from 2 to 6. The glass transition temperature (Tg) of the norbornene-based polymer (Β) is generally from 100 to 250 t, preferably from 110 to 22 Torr, more preferably from 115 to 2001. When the Tg is too low, the heat distortion temperature is too low, and there is a problem that the heat resistance is caused, and the optical characteristics caused by the temperature of the obtained molded article or film are excessively large. On the other hand, when the Tg is too high, the processing temperature must be increased, whereby the resin composition is thermally deteriorated. &lt;Resin composition and optical film&gt; The resin composition and optical film of the present invention are composition ratios of the above styrene-based copolymer (A) and norbornene-based polymer (B) ((A) / (B)) When expressed by weight ratio, the styrene-based copolymer/norbornene-based polymer = 5/95 to 70/30, preferably 15/85 to 60/40, more preferably 20/8 0 ~5 0/50 range. When the amount of the styrene-based copolymer (A) to be added is in the above range, an optical film having reverse wavelength dispersion can be obtained by stretching after film formation. Moreover, the strength of the film can also be increased. When the amount of the styrene-based copolymer (A) added is less than the above lower limit, the stretched film obtained from the resin composition may not exhibit reverse wavelength dispersibility. When the amount of the styrene-based copolymer (A) added exceeds the above upper limit, the heat resistance of the obtained resin composition or optical film is lowered, or the strength of the optical film -51 - 200838917 is lowered. The resin composition and the optical film may further contain a smoky resin.

Examples of the ultraviolet absorber include 2,4-dihydroxybenzophenone, 2-52-200838917 hydroxy-4-methoxybenzophenone, and 2·(2Η-benzotriazol-2-yl). )_4,6_bis(1-methyl-1-phenylethyl)phenol, 2·(2H-benzotriazol-2-yl)-4,6-di-tert•pentylphenol, 2- Benzotriazol-2-yl 4,6-di-tert-butyl acid, 2,2'-methyl-bis[4-(1,1,3,3-tetramethylbutyl)-6- [(2H-benzotriazol-2-yl)phenol]] and the like. The amount of the additives to be added is usually from 0.01 to 5 parts by weight, preferably from 5.00 to 4 parts by weight, based on 100 parts by weight of the resin composition. In addition, additives such as a slip agent can be added for the purpose of improving the processability. &lt;Method for Producing Resin Composition&gt; The resin composition of the present invention can be obtained, for example, by the following methods (i) to (iii). (i) A method in which a styrene-based copolymer (A) and a norbornene-based polymer (B) are mixed in an arbitrary component using a biaxial extruder or a roll kneader. #( ϋ ) A method in which a norbornene-based polymer (B) is dissolved in a solution of a suitable solvent to add and mix a styrene-based copolymer (A). The (Hi) styrene-based copolymer (A) or the solution and the norbornene-based polymer (B) or the solution are mixed and dissolved, and then desolvated by a devolitizer or an extruder. As the solvent to be used in this case, a polymerization solvent used for the production of the styrene-based copolymer (A) or the norbornene-based polymer (B) or a general solvent used in the solvent casting method of the optical film can be used. Since the resin composition obtained by the above method contains a polymer having a high molecular weight, an optical film excellent in film strength can be obtained from -53 to 200838917. Further, the resin composition solution obtained by the above (π), (iii) or the like is introduced into an extruder, and the volatile component in the resin composition solution is removed in an extruder, and then molded into a film or a wire. After the shape, the melt extrusion molding (hereinafter, simply referred to as extrusion molding) is carried out to obtain a molded body or an optical film. &lt;Production Method of Optical Film&gt; The optical film of the present invention is obtained by forming a film by a melt forming method, a solution casting method (solvent casting method), or the like. The solvent casting method may, for example, be a liquid in which the resin composition of the present invention is dissolved or dispersed in a solvent to have a moderate concentration, and is injected into a suitable carrier, or coated and dried, and then peeled off from the carrier. When the resin composition of the present invention is dissolved or dispersed in a solvent, the concentration of the resin composition is generally from 1 to 90% by weight, preferably from 5 to 50% by weight, more preferably from 1 to 35% by weight. . If the concentration of the resin is less than the above, it is difficult to ensure the thickness of the film, and foaming due to evaporation of the solvent may cause problems such as difficulty in obtaining surface smoothness of the film. On the other hand, when the above concentration is exceeded, the thickness or surface of the optical film obtained when the viscosity of the solution is too high is difficult to be uniform, which is not preferable. Further, the viscosity of the above solution at room temperature is generally 1 to 1, 〇00, 〇〇〇(mPa·s), preferably 10 to 500,000 (mPa-s), more preferably 100 to 200,000 (111?&amp;;3), particularly preferably from 1,000 to 100,000 (11^&amp;1 -54-200838917) The solvent used herein may, for example, be a hydrocarbon solvent such as cyclohexane, cyclopentane or methylcyclohexane. , an aromatic solvent such as benzene, toluene or xylene, methyl cellosolve, ethyl cellosolve, cellosolve such as 1-methoxy-2-propanol, diacetone alcohol, acetone, cyclohexane a ketone solvent such as a ketone, methyl ethyl ketone, 4-methyl-2-pentanol or methyl isopropanone; an ester solvent such as methyl lactate, methyl acetate, ethyl acetate or butyl acetate; The halogen such as chloroform contains a solvent, an ether solvent such as tetrahydrofuran, dioxane, dimethoxyethane or 1,3-dioxirane, or an alcohol solvent such as 1-butanol or 1-pentanol. The SP 値 (solubility parameter) other than the above is generally 1 〇 30 30 (MPa 1/2), preferably 10 〜 25 (MPa 172 ), more preferably 15 〜 25 ( MPa 1/2 ), and particularly preferably 17 〜 20 a solvent in the range of (MPa1/2), An optical film having excellent surface uniformity and optical characteristics can be obtained. The above solvents can be used singly or in combination of two or more kinds. When two or more kinds of solvents are used, it is preferred that the sp 値 as a mixture is in the above range. The SP 値 can be obtained from the weight ratio. For example, when the mixture of the two is used, the weight fraction of each solvent is represented by w 1w 2 , and when SP 値 is represented by S P1, SP 2 , the sp値 of the mixed solvent It can be obtained by the following formula: Calculating the obtained enthalpy. Preparation of the resin solution The temperature at which the composition of the thermoplastic resin-55-200838917 of the present invention is dissolved in a solvent may be room temperature or high temperature. A well-balanced solution can be obtained by thorough stirring, and a coloring agent such as a dye or a pigment can be appropriately added to the solution as necessary, and a leveling agent can be added to improve the surface smoothness of the optical film. It can be used as a general coating agent, and for example, a fluorine-based nonionic surfactant, a special acrylic coating agent, a decane-based coating agent, or the like can be used. The method φ produced by the solvent casting method can be applied to a metal drum, a steel strip, polyethylene terephthalate (PET) or polynaphthalene by using a mold extrusion die or applicator. A general method for drying and removing a solvent from a substrate such as a polyester film such as polyethylene terephthalate (PEN) or a polytetrafluoroethylene tape, and then using a spray, bristles, and roller coating. The resin composition solution is applied onto the substrate by means of cloth or dipping, and then the solvent is dried and removed, and then the film is peeled off from the substrate to be produced. The thickness or surface smoothness and the like can be controlled by repeating the coating. • When a polyester film is used as the substrate, a surface treated film can also be used. As a method of surface treatment, a hydrophilization treatment method which is generally performed, for example, an acrylic resin or a resin containing a sulfonic acid base or a method of laminating a laminate, or a corona discharge treatment may be mentioned. A method of increasing the hydrophilicity of the surface of the film, and the like. The drying (solvent removal) step of the solvent casting method is not particularly limited, and may be a method generally used. For example, a method in which a plurality of rolls are passed through a drying furnace may be performed, but the drying step may be caused by evaporation of a solvent. In the case of bubbles, the characteristics of the film are remarkably lowered. Therefore, in order to avoid this, the step of drying -56-200838917 is carried out in a plurality of steps of two or more stages, and it is preferred to control the temperature or the amount of air in each step. Further, the amount of the residual solvent in the optical film is usually 1% by weight or less, preferably 5% by weight or less, more preferably 2% by weight or less, and particularly preferably 1.% by weight or less. In the case where the amount of the residual solvent is 1% by weight or more, when the optical film is actually used, the dimensional change becomes large over time. Further, since the residual solvent lowers the Tg, the heat resistance is also lowered, which is not preferable. Further, in order to smoothly carry out the stretching step described later, it is necessary to appropriately adjust the amount of the residual solvent to be within the above range. Specifically, the phase difference in the extension alignment is stabilized so as to be uniformly expressed, and the residual solvent amount is usually from 10 to 0.1% by weight, preferably from 5 to 0.1% by weight, more preferably from 1 to 0.1% by weight. The residual processing can be easily performed or the control of the phase difference can be facilitated by the residual trace amount of solvent. The thickness of the optical film of the present invention is generally from 0.1 to 3,000 μm, more preferably from 1 to 1, 〇〇〇 μπι, more preferably from 1 to 5 00 μπι, most preferably from 5 to 300 μπι. When the thickness of 〇·1 μπι is not reached, the treatment is substantially difficult. On the other hand, when it is 3,000 μπ or more, it is difficult to roll into a roll shape. The thickness distribution of the optical film of the present invention is generally within 20% of the average enthalpy, preferably within 10% of the soil, more preferably within 5% of the soil, and particularly preferably within ±3%. Further, the variation in thickness per icm is generally 1% by mole or less, preferably 5% or less, more preferably 1% or less, and particularly preferably 0.5% or less. By performing the relevant thickness control, it is possible to obtain a homogeneous optical film while preventing uneven phase difference of transmitted light when extending the alignment. -57- 200838917 As an extrusion molding method, the resin can be melted by an extruder, and the gear pump is used for quantitative supply, and the metal filter is filtered to remove impurities. The mold is used to impart a film shape, and is generally used. The puller cools the film and uses a coiler for winding. As the extruder used for extrusion molding, any one of a single shaft, a two shaft, a star type, a melt kneader, and a Banbury mixer type can be used, and a uniaxial extruder is preferably used. Further, the spiral shape of the extruder may be a discharge port type, a Durum head type, a double spiral type, a full spiral type, a barrier type, or the like, and a compression type may be a slow compression type or a rapid compression type, and may be a full spiral. A slow compression type or a barrier type is preferred. Regarding the gear pump used for metering, the resin that is returned from the downstream side between the gears is loaded into the internal lubrication method in the system and the external lubrication method that is discharged to the outside, but the thermal stability is not good. The case of the polymer is preferably an external lubrication method. The gear teeth of the gear pump are divided in such a way that, for the shaft, the spiral pattern is better from the viewpoint of metering stability than the parallel direction. Examples of the filter used for foreign matter filtration include an active disk type, a candle filter type, a movable type, and a sieving, and it is preferable that the distribution of the residence time is small, and the active disk type which can enlarge the filtration area is preferable. Examples of the filter element include a metal fiber sintered type, a metal powder sintered type, and a metal fiber/powder laminated type. The shape of the center hole of the filter may be an outflow type, a hexagonal column internal flow pattern, or a cylindrical internal flow pattern, but the retention portion may have a small shape, and any shape may be selected. -58- 200838917 The molten resin is discharged from a mold and formed into a target film after the cooling drum is cured by adhesion. Regarding the shape of the mold, it is necessary to make the resin inside the mold flow uniformly, and to maintain the uniformity of the thickness of the film, the pressure distribution inside the mold near the mold must be constant in the width direction. Further, ^ the flow rate of the resin in the width direction is almost constant, and the fine adjustment of the flow rate at the exit of the mold is performed by the lip opening degree, and when it is kept constant within an adjustable range, it is necessary for obtaining thickness uniformity. . The Φ manifold shape to satisfy the above conditions is preferably a hanger type, and the straight manifold, the fishtail type, and the like are less likely to be distributed in the width direction. Further, in order to make the thickness distribution of the film uniform, it is important that the temperature at the exit of the mold is distributed in a wide direction, and the temperature distribution is preferably ±1 ° C or less, more preferably ± 0.5 ° C or less. . When the temperature exceeds U°C, temperature unevenness occurs in the width direction, and the melt viscosity of the resin is poor, resulting in uneven thickness and uneven stress distribution. In the process of performing the stretching operation, the phase difference is less likely to occur. • The lip opening of the mold exit (hereinafter referred to as “lip gap”) is generally 0.3 to 1.5 mm, preferably 0.3 to 1.2 mm, more preferably 〇·35 to 1.0 mm. . If the lip gap is less than 0.3 mm, • If the resin pressure inside the mold is too high, the resin may be poorly leaked from the outside of the molded lip. On the other hand, when the lip gap exceeds 1.5 mm, the resin pressure of the mold hardly rises, so that the thickness uniformity in the width direction of the film is deteriorated. Examples of the method of adhering and curing the film extruded from the mold include a nip roll method, an electrostatic addition method, an air knife method, a vacuum method, and a calendering method of -59 to 200838917. The film thickness can be selected according to the application. It is preferable to perform various surface treatments on the surface of the cooling roll for which the film extruded from the mold is to be solidified, similarly to the inner cylinder of the extruder, the inner surface of the extrusion die, and the like. Examples of the material of the extruder (a cylinder, a spiral, etc.) and a mold extrusion die include stainless steel materials such as SCM steel shovel and SUS, but are not limited thereto. Further, on the inner surface of the extruder measuring cylinder, the mold extrusion die, and the spiral surface of the extruder, TiN, TiAIN, and the like are formed by applying a plating method such as chromium, nickel, or titanium to a PVD (Physical Vapor Deposition) method. A film such as TiCN, CrN, or DLC (diamond-like carbon), a tungsten-based material such as WC, or a ceramic such as cermet is sprayed, and the surface is nitrided. Such a surface treatment is preferred from the viewpoint of reducing the coefficient of friction with the resin and obtaining a molten state of the uniform resin. The resin temperature (extruder cylinder temperature) at the time of producing the optical film of the present invention is usually 200 to 350 ° C, preferably 220 to 320 ° C. If the resin temperature is less than 200 ° C, the resin composition cannot be uniformly melted, and when the other surface exceeds 350 ° C, the resin composition is thermally deteriorated during melting, and it is difficult to produce a high-quality film excellent in surface properties. Further, in the above temperature range, the glass transition temperature (Tg) of the resin composition is particularly preferably in the range of Tg + 120 ° C to Tg + 160 ° C. For example, the resin composition has a Tg of only 130 ° C, and a particularly favorable temperature range for the film production is from 2 50 ° C to 290 ° C. The resin composition of the present invention can suppress the crystallization (white turbidity) of the film at a high temperature as described above and has excellent compatibility, so that the extrusion moldability is good. As an index of the extrusion characteristics, the resin composition used has a melt flow rate (MFR) of -60 to 200838917 at 260 ° C of from 10 〇 20 〇 g/10 min, preferably from 15 to 150 g/10 min. Good for 30~120g/10min. Further, the melt flow rate is preferably ≤ when the total amount of the resin composition is constant, and the deviation is preferably within ±10%, particularly preferably within 5%. When the melt flow rate is set to a predetermined timing, the pressure fluctuation during the extrusion processing can be suppressed, and a film having excellent film thickness uniformity can be obtained. Further, the shearing speed at the time of melt extrusion is generally 1 to 500 (?/sec), preferably 2 to 350 (?/sec), more preferably 5 to 200 (1/sec). When the shearing speed at the time of extrusion is less than 1 (1/sec), the resin composition cannot be uniformly melted, and an extruded film having a small thickness unevenness cannot be obtained. On the other hand, when it exceeds 500 (1/sec), The shearing force is too large, and the resin and additives may decompose and deteriorate, causing defects such as foaming, molding lines, and deposits on the surface of the extruded film. The thickness of the optical film of the present invention is generally from 1 〇 to 8 00 μηη, preferably from 20 to 500 μηη, more preferably from 40 to 500 μπι. When the thickness is less than 10 μm, the mechanical strength is insufficient, and post-processing such as stretching processing is difficult. On the other hand, when the thickness exceeds 800 μm, it is difficult to produce a uniform film such as thickness or surface properties. The film is also difficult to take up. The thickness distribution of the roll film (ROLLED WEB FILM) of the present invention is generally within 5% of the average enthalpy, preferably within ± 3%, more preferably within 1% of the soil. When the thickness distribution exceeds ± 5 %, when the stretching treatment is performed as an optical film, phase difference unevenness is likely to occur. &lt;Extended Film&gt; -61 - 200838917 The stretched film of the present invention can be obtained by further subjecting the optical film of the present invention obtained by the above method to heat stretching, and can be used as a film which imparts a phase difference to light transmission. Specifically, it can be produced by a known shaft stretching method, a biaxial stretching method, or a Z-axis stretching method. It is possible to use a transverse one-axis extension method by a tenter method, a roll-to-roll compression extension method, a vertical axis extension method using a circumferential speed difference, or a two-axis extension method in which a horizontal axis and a vertical axis are combined. The extension method by the blow molding method and the like. In the case of the Φ one-axis stretching method, the stretching speed is usually from 1 to 5,000%/min, preferably from 50 to 1,000%/min, more preferably from 1 to +1, 〇〇〇%/min. The biaxial stretching method is a case where the stretching is performed in the two directions at the same time, or the stretching is performed in the direction different from the initial extending direction after the one-axis stretching. At this time, the angle of intersection of the two extension axes for controlling the shape of the refractive index 楕 round body is not particularly limited as long as it depends on the desired characteristics, and is generally in the range of 120 to 60 degrees. Further, the stretching speed is the same or different in each extending direction, and is generally 1 to 5,000%/min, preferably 50 to 1,000%/min, more preferably 1 to 1%, 〇〇〇%/ Minutes, especially good for 1〇〇~500%/min. The elongation processing temperature is not particularly limited, and the glass transition temperature Tg of the resin composition containing the styrene-based polymer (A) and the norbornene-based polymer (B) is used as a reference. It is usually Tg ± 30 ° C, preferably Tg ± 15 ° C, more preferably in the range of Tg - 5 to Tg + 15 ° C. When it is within the above range, generation of phase difference unevenness can be suppressed. Further, the glass transition temperature of the resin composition in the present specification is the external glass transition starting temperature obtained according to Japanese Industrial Standard K7 121 'The resin composition of the present invention is benzene-62-200838917 ethylene-based polymer (A) It has excellent compatibility with the norbornene-based polymer (B), and is solid and measurable. Further, even if the resin composition of the present invention is subjected to elongation processing at such a high temperature, by controlling the content ratio of each structural unit constituting the styrene-based copolymer (A), it is possible to suppress the film caused by crystallization or phase separation of the film. The transmittance is lowered and the turbidity is imparted, and excellent compatibility is imparted, and the heat extension workability is also good. The stretching ratio is not particularly limited depending on the desired characteristics, and is generally 1.0 1 to 10 times, preferably 1.03 to 5 times, more preferably 1.03 to 3 times. When the extension ratio is 1 〇 or more, the control of the phase difference is difficult. The stretched film may be directly cooled, but is preferably set to a heating system of at least 10 seconds, preferably 30 seconds to 60 minutes, more preferably 1 minute to 60 minutes, in a temperature range of Tg-20 °c to Tg. Thereby, the phase difference of the transmitted light is less with time, and a stable optical film can be obtained. The dimensional shrinkage rate by heating of the optical film of the present invention which is not subjected to the stretching process is generally 5% or less, preferably 3% or less, more preferably 1% or less, when heated at 100 ° C for 500 hours. It is 0.5% or less. Moreover, the dimensional shrinkage rate by heating of the stretched film of the present invention is generally 10% or less, preferably 5% or less, more preferably 3% or less, when heated at 1 ° C for 500 hours, particularly preferably 1% or less. In order to make the dimensional shrinkage ratio within the above range, in addition to the selection of the monomer (6) or the selection of other copolymerizable monomers in the present invention, it is also a powerful means to adjust the conditions of the stretching method. The stretched film obtained as described above is such that the molecules are aligned by stretching and the phase difference is imparted by the transmitted light, and the phase difference can be controlled by the stretching ratio, the stretching temperature of -63 to 200838917, or the film thickness. For example, when the film thickness before stretching is the same, the film having a larger stretching ratio tends to have a larger absolute phase difference of the transmitted light. Therefore, by changing the stretching ratio, an optical film that imparts a transmitted light having a desired phase difference can be obtained. . On the other hand, when the stretching ratio is the same, the thicker the film thickness before stretching, the greater the absolute difference in the phase difference of the transmitted light tends to be. Therefore, by changing the thickness of the film before stretching, the transmission of the desired phase difference can be obtained. Optical film of light. Further, in the extended processing temperature range, the lower the stretching temperature, the greater the absolute difference in the phase difference of the transmitted light. Therefore, by changing the stretching temperature, an optical film which imparts a transmitted light having a desired phase difference can be obtained. The extension film imparts a phase difference to the transmitted light, and is not particularly limited depending on the application. When used in a liquid crystal display element, an electroluminescence display element, or a wavelength plate of a laser optical system, it is generally 1 to 1 0,000 nm, preferably 10 to 2,000 nm, more preferably 15 to 1,000 nm. Further, the uniformity of the phase difference of the light transmitted through the stretched film is preferably high, and the variation of the phase difference at a wavelength of 550 nm is generally ±20% or less, preferably 10% or less, more preferably ±5. %the following. That is, the phase difference at a wavelength of 550 nm is 20% or less, preferably 10% or less, more preferably 5% or less, of the average average enthalpy. When the deviation of the phase difference exceeds 20%, when used in a liquid crystal display element or the like, color unevenness occurs, and the performance of the display body is deteriorated. Further, in the optical film of the present invention, the ratio of the phase difference Re (650) at a wavelength of 650 nm to the phase difference Re (450) at a wavelength of 450 nm (Re(650) / Re(450)) is 1.8 to 1 Preferably, it is 1.7 to 1, -64 to 200838917, more preferably in the range of 1.6 to 1. In the optical film satisfying such conditions, when the phase difference of the wavelength λ is Re ( λ ), the Re of Re (λ) /λ can be made almost constant in the entire wavelength range of 400 to 800 11111. &lt;Polarizing Plate&gt; The optical film of the present invention can be used not only as a single layer but also as a polarizing plate. Further, the polarizing plate can be laminated to other films, sheets, and substrates. When laminating, an adhesive or an adhesive can be used. As these adhesives and adhesives, those having excellent transparency are preferable, and specific examples thereof include mixed natural rubber, synthetic rubber, vinyl acetate/vinyl chloride copolymer, polyvinyl ether, acrylic, and denatured polyolefin, and A curing adhesive such as a curing agent such as an isocyanate, a dry laminating adhesive for a polyurethane resin solution and a polyisocyanate resin solution, a synthetic rubber-based adhesive, and an epoxy-based adhesive are added thereto. Further, the polarizing plate is intended to improve the layering property with other film sheets, substrates, etc., and the adhesive layer or the adhesive layer may be laminated in advance.

Both of the Tg from the individual polymers disappeared, and a single peak was confirmed, and it was judged that the styrene-based copolymer 7 A and the norbornene-based resin 5 B were all dissolved in any of the compositions. The Tg in Example 10 was 128 ° C, and the Tg in Example 11 was 124. Hey. The composition of Example 1 was formed into a film in a melt extrusion apparatus having a polymer filter of 5 μm, and the film was formed at a speed of 10 μm/min at 260 ° C. The subsequent pressure difference is a film having a lower film thickness of 2 MPa, a width of 500 mm, and a film thickness of 250 μm. It is a relatively small coloring transparent film of ΗΑΖΕ = 0.33 and ΥΙ = 0·3. From the individual peaks of the Tg of 2 2 8 ° C of the film, it was judged that the styrene-based copolymer 7 a and the ice-89-200838917 olefinic resin 5B were not separated after the film formation. The film was cut out to 10 cm x 10 cm, and the width in the lateral direction was maintained at a constant i 〇 cm for wide extension. Extension conditions. Extension temperature = 1 3 3 C (T g + 5 °C), elongation speed = 300 mm/min, and stretching ratio in the longitudinal direction = 3.0 times. After stretching, the film thickness = 80 μπι. The phase difference between 5 5 0 nm and 650 nm is 140 nm, 145 nm, and the phase difference ratio (wavelength dispersion) of 65 0 nm to 5 50 nm (wavelength dispersion) = 1.036. The birefringence at 550 nm and 650 nm is caused by phase difference/film Calculated by thickness, each is 0.001 75,0·00181. Also, the NZ coefficient is 1.025. The result is a watch! Shown. Further, the composition of Example 11 was molded into a molded article having a thickness of 3 mm at 28 ° C using an injection molding machine. The phase difference of the molded article is a very small number of 2 nm, and the low birefringence, YI II. 7 and coloring are also small. [Example 12] The styrene-based copolymer 10A synthesized in Production Example 10 and the norbornene-based resin 5B before desolvation obtained in Production Example 15 were prepared and adjusted at a ratio of 6 g/14 g. Filming was carried out in the same manner as in Example 1 to obtain a film having a thickness of 190 μm and Haze = 〇·3. The results are shown in Table i. [Comparative Example 1] A substituted film of a mixture of -90-200838917 of the polymer 1B obtained in Production Example i was carried out in the same manner as in Example 1 except that the substituted polymer 1A was made of PS Japan. As a result, a transparent film could not be obtained regardless of whether or not a solvent was used. Further, after the evaluation of the compatibility under heating, phase separation of the island structure at 280 °C was observed. The results are shown in Table 2. [Comparative Example 2] Polymer 1 B obtained in Production Example 1 was used in the same manner as in Example 1 except that the substituted polymer 1 A was used as a maleic anhydride/styrene copolymer (DYLARK232) manufactured by N 〇 vachemica 1 s. Casting of the mixture into a film. As a result, when dichloromethane was used as the solvent, a transparent film could not be obtained. On the other hand, when toluene is used as a solvent, a transparent film can be obtained, but the drying speed is very slow and it cannot be used in industrial production. Further, the compatibility of the cast film obtained by using toluene was evaluated for the compatibility under heating, and microphase separation at 280 ° C was observed. Further, it was examined by melt-kneading using a two-axis extruder, and it was found that only white turbid particles at 290 ° C were obtained. The results are shown in Table 2. [Comparative Example 3] A polymer was synthesized in the same manner as in Production Example i except that p-isopropenylphenol was used instead of styrene acetate. The molecular weight of the obtained polymer was Mw = 20,000 (Mw/Mn = 2.2), and the reaction rate was 57%. When the obtained polymer was cast into a film of a mixture of the polymer obtained in Production Example 5, the film strength was low, and the degree of characteristic evaluation could not be achieved. The results are shown in Table 2, 0 - 91 - 200838917 [Comparative Example 4] The polymer 1B 2 〇g obtained in Production Example 11 was cast into a film in the same manner as in Example 1 to obtain a thickness of 140 μΠ1, HaZe=〇·3. The film obtained by the film 与 was similar to that of Example 1 and was extended to 2 times at the free end 1 axis of 1771. The maximum stress during extension is 40 kgf/cm2. The film thickness of the obtained film was 100 μm, and the phase difference (Re) was measured to obtain Re45 〇 = 396 nm, Re550 = 388 nm, and Re6 5 0 = 3 84 nm. Also, the NZ coefficient is 1. The results are shown in Table 2.
