Description of the Invention (1) Invention of Europium This invention is about a syndiotactic polystyrene oriented film. In particular, the invention refers to a syndiotactic polystyrene oriented film, regardless of the thickness of the film, which has a smooth surface and good handling properties, that is, the invention relates to a kind of Oriented film composed of styrene polymer with regular structure has excellent flatness, printability, heat resistance, scratch resistance and wear resistance, and can have satisfactory mechanical properties and electrical properties. Transparency and chemical resistance. It has various applications such as packaging materials, industrial materials, magnetic tapes, capacitors, dielectric films, photographic manufacturing technology film, adhesive tape base film, and flexible printed circuit base film. In recent years, a styrene-type polymer having a syndiotactic structure has been developed (see, for example, JP-A 62-104818), and many efforts have been made to produce an oriented film using this styrene-type polymer (see For example, JP-A 1-110122, JP-A 1-1 68709, JP-A 1-1 82346, JP-A 2-27973 1, JP-A 3 -74437, JP-A 3-1 09453, JP-A 3-99828, JP-A 3-124427, JP-A 3-131644). Syndiotactic polystyrene type biaxially oriented film has excellent heat resistance, electrical properties and transparency, so it is expected to be found in, for example, Various applications such as magnetic tapes, film for photographic production and sale, dielectric films for capacitors, and packaging materials. When this film is used for these purposes, the surface of the film needs to be smooth. Its thickness is thin, and it can achieve excellent flatness, printability, and resistance -3-{Please read the precautions on the back before filling this page ) This paper scale is applicable to China National Standard (CNS) A4 specifications (210x297 mm) A6 B6 Printed by the Employee Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs V. Invention description (2) Thermal, scratch resistance and abrasion resistance. However, if the surface of the syndiotactic polystyrene intercalated biaxially oriented film is smoothed and the thickness of the film is further reduced, the handling during film preparation and conversion will deteriorate. Regarding a film with good slip properties, it is known to add inorganic particles to make it have a surface roughness (Ra) within a specific range and a limited static friction coefficient (see, for example, JP-A 3 -74437). A conventional film having good slippage as described above can exhibit excellent handleability when the conversion process is performed at a low speed, but when the conversion processing rate is increased, the handleability of the film will significantly deteriorate. When the thickness of the syndiotactic polystyrene-type biaxially oriented film is reduced, the handleability tends to deteriorate. What's more, the film made by adding inorganic particles to make the surface roughness (Ra) and the static friction y number fall within a specific range also has the tendency as described above. For this reason, even if a film having a certain thickness can show excellent handleability, when the thickness of the film changes, the desired handleability becomes worse. Fa Rong said that under these circumstances, the present invention has made intensive and in-depth research on syndiotactic polystyrene oriented films, and found that regardless of the thickness of the film, by adjusting the surface roughness of at least one side of the film Degree SAa and air escape rate can obtain excellent handleability, and it is found that excellent flatness can be obtained by adjusting the emission rate N z (refractive index) in the thickness direction of the film and the heat shrinkage at a specific temperature, and thus completed this invention. —4— ..............

Description of invention (5) The styrene-based polymer with a minimum of 10,000 cannot provide any Stretching film with excellent heat resistance. Although the upper limit of the weight average molecular weight is not particularly limited, it is preferably 1,500,000. Molecules larger than 1,500,000 are undesirable because increasing the orientation tension may cause the film to break. The syndiotactic polystyrene oriented film of the present invention has a three-dimensional surface on at least one side and a roughness SAa of from 0.004 to 0.04. If the roughness of the three-dimensional surface is less than 0.004, the handling will be worse. On the other hand, if the surface roughness of Sanxian is greater than 0.04, the film will have various shortcomings: for example, when used as a magnetic tape, its electromagnetic conversion processability will be deteriorated; transparency will be reduced, which is used in the photo production and sales method Is not good; and when used as a dielectric film for capacitors, the dielectric strength will be reduced. The syndiotactic polystyrene oriented film has an air escape rate of 900 seconds or less, preferably 700 seconds or less. In other words, when the air escape rate is adjusted to 900 seconds or less, preferably 700 seconds or less, regardless of the thickness and strength of the film, even during high-speed conversion processing, it can be obtained with excellent treatment Syndiotactic polystyrene oriented film. If the air escape rate is higher than 900 seconds, the handling during the high-speed conversion process will be deteriorated. For example, when the film is wound onto the drum at high speed, the air is trapped between the film on the drum, and the film will have a tendency to wrinkle, so that the obtained roller has an unconstitutional shape or the film will Winding in a zigzag shape in the width direction, due to the lubricating effect of the air trapped between the film layers, as a result, the edge of the roller becomes irregular. -7-This paper scale is applicable to China National Standard (CNS) Grade 4 (210x297 mm) (please read the precautions on the back before filling in this page)-Staple 302380 A6 B6 Printed by the Employees Consumer Cooperative of the Central Bureau of Standards of the Ministry of Economic Affairs V. Description of the invention (6) The three-dimensional surface roughness SAa and air escape rate can be adjusted by the conditions when the film is cracked and by lubricating particles. There is no particular restriction on the type and number of lubricating particles added, as long as the three-dimensional surface roughness SAa and air escape rate fall within the aforementioned specific ranges, respectively. Examples of lubricating particles are lubricating particles that are inactive to syndiotactic polystyrene-based polymers, and are selected from, for example, including: metal vapors such as silica, titanium dioxide, talc, and kaolinite; metal salts such as sialic acid Umbrella, calcium phosphate and sulfuric acid; and organic polymers such as polysilicone resin. These lubricating grains can be used alone or in combination. The average particle size of the lubricating particles may be from 0.01 to 2.0 nm, preferably from 0.05 to 1.5 cm. The degree of dispersion of the particle diameter of the lubricating particles (that is, the ratio of the average particle diameter to its standard deviation) may preferably be 25% or less. If the amount of the lubricating grains is based on the weight of the syndiotactic polystyrene polymer, the preferred range is from 0.005 to 2.0% by weight, and more preferably from 0.1 to 1.0% by weight. The lubricating particles preferably contain at least one particle having an area form factor of 60% or more.

From the weight to the weight, it is 10 for the film. The HZ agent is used to borrow the film. The thin film can be added more thinly. This quasi-appropriate reason is that the orientation C group is not, and the type formula is the amount of ethylenicity. The benzene has a thick electrical weight. The benzene is cracked in the static weight and its resistance is 10 broken. The amount of this type of chemical will be added to the film and the film will be stretched to resist the thinning of benzene. ,. In the Ming Dynasty, the originator is ordered in a short period of time. If the dosage is more stable, or a lot of pull (please read the precautions on the back before filling the nest page), the Central Bureau of Standards of the Ministry of Economic Affairs prints 1.600 to 1.623 , Preferably from 1.600 to 1.621, and more preferably from 1.600 to 1.619. Generally, the syndiotactic styrene-type polymer contains benzene in the side chain, and when a film is prepared from such a polymer, its refractive index Nz in the thickness direction of the film increases as the degree of molecular orientation increases. If the refractive index Nz is greater than 1.623, although the mechanical properties such as the strength of the film can be improved, the film sometimes becomes tearable or brittle. In addition, under these circumstances, the abrasion resistance of the film will also decrease. If the refractive index Nz is less than 1.600, the flatness of the film may be significantly deteriorated in some cases. Therefore, if the emission rate Nz falls within the range from 1.600 to 1.623, the orientation of the silver carp can be suppressed, thereby preventing the film from tearing and making the film softer. Moreover, the crystallinity of the film can be reduced, thereby improving the wear resistance of the film. The syndiotactic polystyrene oriented film of the present invention has a heat shrinkage at 150 * 0 of 3% or less, preferably 2% or less, and more preferably 1% or less. If the thermal shrinkage at 150 t is greater than 3%, the film obtained is not good, because in thermographic printing (thermographic printing), electrophotographic copying (electrophotographic copying)

Invention Instructions (8) Top Projectors (OHPs) (Overhead projectors, copy of original orange), or gravure printing, printing offsets (Pitches) will occur; or in the copying machine or transfer machine used, film clogging will occur. As described above, the syndiotactic polystyrene-oriented film of the present invention can be produced by the conventional method of bracelet making and stretching. First, a polymer mixture containing syndiotactic styrene-type polymers, together with lubricating grains and other optional additives, are dried at a temperature of from 1001C to 150C, preferably at least 3 hours. Then It is then extruded in a molten state through an extruder at a temperature of from 290 ° to 350 ¾. The extrudate is cooled by, for example, air-knife blowing, water-cooling, and electrostatic adhesion methods, thereby obtaining an amorphous unstretched sheet. The extruder used here is not particularly limited, but it can be a single screw extruder or a double screw extruder; it can be an exhaust extruder or a non-exhaust extruder; and it It can be tandem type or single type extruder. Then, the amorphous thin H is stretched in at least one of the directions by conventional methods. If it is a biaxially oriented film, the amorphous thin film is stretched by, for example, tandem biaxial stretching, for example, in the machine direction (MD) and then in the building axis direction (TD) in two stages, that is MD / TD stretching method; or three-stage stretching method, that is, TD / MD / TD stretching method, MD / TD / MD stretching method, or MD / MD / TD stretching method. The stretching method can be selected according to properties such as required strength and dimensional stability.

V. Description of the invention (9) Depending on the stretched film, thermal fixation, MD relaxation, and / or TD relaxation can be performed. The MD stretching method can be carried out using a group of stretching sticks, also «by the Kun-type stretching method. The preferred stretching range is from 1.2 to 5.0. If the draw ratio is less than 1.2, the mechanical strength of the film will be insufficient. If the stretching ratio is greater than 5.0, the TD stretching after winding will become difficult, so that a film with excellent flatness cannot be obtained. The preferred stretching temperature range is from 100 ° to 14010. If the stretching temperature is lower than 1001C, the unstretched sheet cannot be softened, so that stretching becomes difficult. If the stretching temperature is higher than 1 40 t :, the crystallinity of the film will become too high, so that the TD stretching after wrapping will become difficult. In the stretching stage, the heating of the unstretched sheet can be performed using a set of heating rollers, infrared heating devices, or any other heating method. These heating methods can be used alone or in combination. In addition, guide sticks or nip rolls can be used between the preheating stick and the stretching stick. In order to broadcast the aforementioned properties, it is preferable that the MD stretching is performed at least twice in series. In this case, the first stretching is carried out under the condition that the stretching ratio is from 1.1 to 1.4 and the stretching temperature is from 115 ° to 140 °, while the subsequent stretching is performed at the gold portion. 1.2 to 5.0 and the stretching temperature are from 100 ° to 135 °. If the total draw ratio is less than 12, the mechanical strength of the film becomes insufficient. If the stretching ratio is greater than 5.0, the film will tend to break during TD stretching. If the stretching temperature during the first stretching is lower than 11 5 υ, the orientation stress will become -11- This paper scale is applicable to the Chinese National Standard (CNS) A 4 specifications (210X297 mm) f Please read the back Please pay attention to this page. Binding. 302380 A6 B6 Printed by the Employee Consumer Cooperative of the Central Standards Bureau of the Ministry of Economic Affairs. 5. The description of the invention (i〇) is too high, so that the orientation of the unstretched film is excessive, for example, it is difficult Obtain a film having a refractive index Nz of 1.623 or less in its thickness direction ... If the stretching temperature at the first stretching is higher than 14〇υ, the crystallinity of the film becomes too high, so that The thin film will tend to break. And the second drawing will become difficult. If the drawing temperature in the first drawing is lower than 100C, the thin film cannot be softened without drawing, so that the second time Stretching becomes difficult. If the stretching temperature in the second stretching is higher than 135T0, the crystallinity of the film becomes too high, so that the film will tend to break. The TD stretching of post-mine is better Is performed using a tenter. After completing TD stretching, in the machine direction Stretch at least one more time in the transverse axis direction to improve the mechanical strength in that direction. In addition, another method can also be used to stretch the film for the first time in the transverse axis direction, and then stretch it in the machine direction ( (See, for example, JP-A 64-5819, JP-A 1-188322), or eliminate the difference in physical properties between the edge portion and the center portion of the film (see JP-A 3-15225). When preparing a syndiotactic polymer When the styrene-type oriented film has a reflectance Nz of 1.600 to 1.623 in its thickness and has a thermal shrinkage of 150% at 3% or less, in addition to the foregoing conditions, it is important to include in the manufacturing method : At least one stage of stretching is at a stretching temperature from 115 ° to 1401C, with a stretching rate of at least 10,000% / min, preferably at least 15,000% / min, and more preferably at least 20,000% / min.

Description of the invention (11) Obtain a film with the desired mechanical strength and especially excellent flatness. If the stretching temperature is lower than 115, it is not easy to obtain the analysis in the thickness direction of the film The emissivity Nz is 1.623 or less. If the stretching temperature is greater than 130T, it is not easy to obtain a film with excellent flatness. In the case of syndiotactic polystyrene film, if it is applied to the film during stretching The stress is lower than the stress applied to the polyethylene terephthalate type film, so conditions such as temperature and stretching rate are important to obtain excellent flatness. As long as these conditions are met, there are no special restrictions on the stretching method. It is preferable that these conditions satisfy the stretching in the MD direction with a stretching stick, and it is more preferable that the MD stretching is performed at least twice in series. In the manufacture of the syndiotactic polystyrene oriented film of the present invention, after the stretching is completed, the film is subjected to heat treatment or heat fixation at a temperature of 170 ° to 2701C, preferably from 220 ° to 270C (Heat fixation). When heat treatment or heat fixing is performed, and the relaxation ratio in the machine direction and / or the horizontal axis direction is 2% or more at the same time, a film with less heat shrinkage can be produced. _The syndiotactic polystyrene oriented film obtained here has excellent flatness, printability, and heat resistance, and has satisfactory mechanical and electrical properties and the required transparency and chemical resistance.
