Description

[Technical field]

[0001] The present invention relates to a composition containing an alkoxy-N-substituted propanamide, a solvent for synthesizing polyimides using said composition, and uses thereof. [Background technology]

[0002] Amide solvents dissolve water and various organic and inorganic substances well, have high boiling points and flash points, and are thermally and chemically stable. They are widely used industrially as reaction and purification solvents, cleaning agents, resist strippers, etc. Conventionally, N-methyl-2-pyrrolidone (NMP), dimethylformamide (DMF), and dimethylacetamide (DMAC) are representative amide solvents, but they are prone to cause inflammation when they come into contact with the skin or eyes, and are suspected of being carcinogenic and teratogenic, making them harmful to the human body a problem. Therefore, alkoxy-N-substituted propanamides have recently been attracting attention as solvents that have amide groups, alkyl groups, and ether bonds, have high dissolving power, and are less irritating to the skin, and their manufacturing methods have been actively studied (Patent Documents 1 and 2).

[0003] However, since alkoxy-N-substituted propanamides have an ether bond and an amide bond in their structure, they have the disadvantage that in a natural environment, they slowly turn into peroxides due to the action of oxygen, i.e., so-called autoxidation and hydrolysis, which are caused by light, heat, oxygen, metal ions, moisture, microorganisms, etc., and deterioration due to the combined action of these main factors progresses over time.

[0004] As described above, there is a demand for stabilized alkoxy-N-substituted propanamides that do not deteriorate during long-term storage or use under ambient air, but an effective stabilization method has not yet been known. [Prior art documents] [Patent documents]

[0009] The composition containing the alkoxy-N-substituted propanamide and the deterioration inhibitor of the present invention (hereinafter referred to as the alkoxy-N-substituted propanamide composition for short) is not adversely affected by deterioration factors such as heat, light, oxygen, etc., and is stabilized without deterioration for long-term storage, long-term use, and use in the open air. The mechanism of deterioration over time of the alkoxy-N-substituted propanamide, which is the main component of the composition, is unknown, but the present inventors believe that it is due to the combined action of influencing factors such as heat, light, oxygen, metal ions, water, and microorganisms. By coexisting with a specific deterioration inhibitor, the composition of the present invention is highly stable against deterioration factors such as heat, light, and oxygen, and can be used for long-term storage and various preparations and products, not only for high-purity products (purity of 99% or more) but also for industrial grade alkoxy-N-substituted propanamide (purity of 95% or more and less than 99%). DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] The present invention will now be described in detail. The composition of the present invention comprises an alkoxy-N-substituted propanamide and an anti-degradation agent. The alkoxy-N-substituted propanamide is represented by the general formula (1) (wherein R 1 ~R 3 each independently represents a linear or branched, saturated or unsaturated alkyl group, hydroxyalkyl group, aminoalkyl group, or alkyl ether group having 1 to 18 carbon atoms, or an alicyclic hydrocarbon or aromatic hydrocarbon having 6 to 18 carbon atoms; R 4 represents a hydrogen atom or a methyl group. 2 and R 3are each independently a hydrogen atom (except when both are hydrogen atoms), or, together with the nitrogen atom carrying them, a saturated 5- to 7-membered ring (including one having an oxygen atom), and are β-alkoxy-N-substituted propanamide and β-alkoxy-N,N-disubstituted propanamide. [ka]

[0011] β-Alkoxy-N-substituted propanamides and β-alkoxy-N,N-disubstituted propanamides are R 1 , R 2 and R 3 A specific example of a compound is β-methoxy-N-methylpropanamide (R 1 and R 2 is a methyl group, R 3 is a hydrogen atom), β-methoxy-N,N-dimethylpropanamide (R 1 , R 2 and R 3 where R is all methyl groups), β-butoxy-N,N-dimethylpropanamide (R 1 is a butyl group, R 2 and R 3 where R is a methyl group), β-lauroxy-N,N-dimethylpropanamide (R 1 is a lauryl group, R 2 and R 3 where R is a methyl group), β-stearoxy-N-hydroxyethylpropanamide (R 1 is a stearyl group, R 2 is a hydrogen atom, R 3 is a hydroxyethyl group), β-phenyloxy-N,N-methylethylpropanamide (R 1 is a phenyl group, R 2 is a methyl group, R 3 where R is an ethyl group), β-isooctyloxy-N-dimethylaminopropylpropanamide (R 1 is an isooctyl group, R 2 is a hydrogen atom, R 3is a dimethylaminopropyl group), β-cyclohexyloxy-N,N-methyloleylpropanamide (R 1 is a cyclohexyl group, R 2 is a methyl group, R 3 is an oleyl group). These compounds may be used alone or in combination of two or more.

[0012] In addition, β-alkoxy-N-substituted propanamides and β-alkoxy-N,N-disubstituted propanamides can be represented by the general formula (2) (wherein R 5 is a linear or branched alkyl group having 1 to 18 carbon atoms; R 6 and R 7 each independently represents a linear or branched alkyl group having 1 to 4 carbon atoms (except when both are hydrogen atoms), R 8 represents hydrogen or a methyl group.) is preferred because it is easy to obtain inexpensive industrial raw materials and can be industrially produced in high yields due to a structure with low steric hindrance. Furthermore, β-methoxy-N,N-dimethylpropanamide and β-butoxy-N,N-dimethylpropanamide are particularly preferred because they are highly safe for workers and the environment and are generally handled as industrial products. [ka]

[0013] The deterioration inhibitor used in the present invention can be used without any particular limitation as long as it can prevent or suppress the deterioration of the alkoxy-N-substituted propanamide over time. Specific examples include heat stabilizers, light stabilizers, antioxidants, pH stabilizers, coloring inhibitors, ultraviolet absorbers, dehydrating and drying agents, preservatives, rust inhibitors, and metal ion sequestering agents. These deterioration inhibitors may be used alone or in combination of two or more. In addition, the function of these deterioration inhibitors may change under different environments or conditions of use, and they may sometimes act as heat stabilizers, sometimes as antioxidants, light stabilizers, etc., and one type of compound may simultaneously act as multiple functions, and can be used as a variety of deterioration inhibitors. Furthermore, it is preferable to use different deterioration inhibitors in combination because of the synergistic effect of the different deterioration inhibitors.

[0014] The heat stabilizer used in the present invention is any additive capable of improving the thermal stability of the alkoxy-N-substituted propanamide. The boiling points of alkoxy-N-substituted propanamides at normal pressure vary depending on the structure. For example, the boiling point of β-methoxy-N,N-dimethylpropanamide is 216°C, that of β-butoxy-N,N-dimethylpropanamide is 252°C, that of β-hexaloxy-N,N-dimethylpropanamide is estimated to be 270°C (measured value: 120°C / 1 torr), that of β-octyloxy-N,N-dimethylpropanamide is estimated to be 296°C (measured value: 146°C / 1 torr), and that of β-lauroxy-N,N-dimethylpropanamide is estimated to be 360°C (measured value: 170°C / 1 torr). These alkoxy-N-substituted propanamides can be used at high temperatures as a high-boiling point solvent, cleaning agent, stripping agent, etc., but it is preferable to add a heat stabilizer in order to use them stably for long periods of time in a high-temperature environment of about 200°C.

[0055] (Appearance of polyimide film) The obtained polyimide film was visually observed to check for the occurrence of defects such as bubbling and cracking. ⊚: Light yellow, transparent, no bubbles or cracks. ◯: Light yellow to yellow, transparent, with slight bubbles or cracks. △: Yellow or translucent with several bubbles or cracks. ×: Yellow to brown or opaque, with numerous bubbles or cracks.

[0056] (light transparency) The obtained polyimide film was left to stand overnight under conditions of a temperature of 23°C and a relative humidity of 50%, and then the light transmittance was measured. The measurement was performed using a haze meter (manufactured by Nippon Denshoku Industries Co., Ltd., NDH-2000) in accordance with JIS K7105. The higher the light transmittance, the better the transparency of the polyimide film.

[0057] (Tensile strength and tensile elongation) The obtained polyimide film was cut into test pieces of 100 mm in length and 10 mm in width, and left to stand overnight under conditions of 23°C temperature and 50% relative humidity, after which a test was performed using a tensile tester (ORIENTEC, Tensilon RTA-100) with a check gap of 50 mm, a tensile speed of 50 mm / min, and n=5. The higher the tensile strength, the higher the strength of the polyimide film. Also, the higher the tensile elongation, the higher the elongation of the polyimide film.

[0058] (coefficient of linear thermal expansion) The obtained polyimide film was cut into test pieces of 20 mm in length and 2 mm in width, and left to stand overnight under conditions of 23°C temperature and 50% relative humidity, and then measured under a nitrogen gas flow using a thermomechanical analyzer (SII NanoTechnology, EXSTAR6000). The measurement method was to increase and decrease the temperature from room temperature to 220°C at a rate of 5°C / min, then increase the temperature a second time at 5°C / min, and measure the average linear expansion coefficient from 50°C to 200°C. The lower the average linear expansion coefficient, the higher the heat resistance and dimensional stability.

[0059] Examples A-2 to A-4 and Comparative Examples A-5 to A-6 In Examples A-2 to A-4, polyimide precursor varnishes were synthesized and polyimide films were produced in the same manner as in Example A-1, except that the diamine components, tetracarboxylic dianhydride components, and solvents (compositions 2 to 4) shown in Table 1 were used, and the resulting varnishes and films were evaluated in the same manner, with the results shown in Table 1. In Comparative Examples A-5 to A-6, polyimide precursor varnishes were synthesized and polyimide films were produced in the same manner as in Example A-1, using NMP as the solvent and MPA containing no deterioration inhibitor, with the results shown in Table 1.

[0060] [Table 1]

[0061] As can be seen from the results shown in Table 1, by adding an antidegradant to the alkoxy-N-substituted propanamide composition of the present invention, a polyimide precursor varnish having high transparency and low viscosity can be produced, and furthermore, the polyimide films obtained using these varnishes have high transparency, high light transmittance, low colorability, and are excellent in strength, elongation, heat resistance, and dimensional stability. The effects of the present invention are due to the synergistic effect of the excellent dissolving power of the alkoxy-N-substituted propanamide and the stabilizing power of the antidegradant, and are not obtained by using only the alkoxy-N-substituted propanamide or a combination of the antidegradant and other solvents.

[0062] A polyimide film produced using the above-mentioned composition of the present invention as a solvent exhibits excellent physical properties and can be suitably used as a surface protective film or interlayer insulating film for semiconductor elements, an insulating layer or spacer layer for organic electroluminescence elements, a planarizing film for thin film transistor substrates, an insulating film for organic transistors, a substrate for light-receiving devices such as flexible printed circuit boards, substrates for flexible devices, substrates for liquid crystal displays, substrates for organic electroluminescence displays, substrates for electronic paper, and substrates for thin film solar cells, as well as a binder for electrodes of lithium ion secondary batteries, an adhesive for semiconductors, and the like.

[0063] In addition, the composition of the present invention has excellent solubility for polyimide precursors such as polyamic acid (polyamic acid) and soluble polyimides, which are the main components of liquid crystal alignment agents, and is therefore suitable for use in the manufacture of liquid crystal alignment agents. In particular, due to the need for lighter weight and thinner designs for mobile applications such as smartphones and mobile phones, liquid crystal alignment films with high mechanical strength, high film hardness, and good electrical properties are desired. In the manufacture of such high-performance liquid crystal alignment films, the composition of the present invention is indispensable as a solvent for liquid crystal alignment agents. The composition of the present invention is composed of an alkoxy-N-substituted propanamide and a deterioration inhibitor, and can dissolve polyimide precursors and soluble polyimides uniformly and at a high concentration. At the same time, in the film formation process in which the obtained liquid crystal alignment agent is applied to a substrate, dried, and baked to produce a coating film, a liquid crystal alignment film with a precisely controlled film thickness and excellent electrical properties such as dielectric constant and conductivity can be obtained.

[0064] Example B-1 0.5 parts of polystyrene and 99.5 parts of composition 5 (MPA containing 2 ppm of c-1 as a deterioration inhibitor) were mixed and stirred at room temperature (25 ° C.) for 30 minutes, then left to stand overnight, and the solubility was evaluated visually. The obtained polymer solution was filtered through a 0.45 μm membrane filter, and the filtrate was used for GPC measurement (Shimadzu Corporation's Prominence Series as the GPC system, Tosoh's TSKgel (α-M) columns were connected in two columns, and Shodex's differential refractive index detector (RI-101) was used as the detector.) was performed five times to evaluate the reproducibility of the weight average molecular weight (Mw) obtained in terms of standard polystyrene. In addition, composition 5 was run as a solvent for 10 hours to confirm the stability of the baseline. The evaluation results are shown in Table 2.

[0065] (Solubility) After standing overnight, the polymer solution was visually inspected for solubility. ◯: High transparency, no cloudiness or separation observed, completely dissolved. △: No layer separation, but cloudy or partially dissolved. ×: Layer separation occurred or the mixture was in an insoluble state.

[0066] (Reproducibility) The reproducibility of molecular weight measurement by GPC was evaluated by the following method. The average molecular weight (weight average) and the upper and lower limit difference (maximum value - minimum value) obtained from five GPC measurements were determined, and the error (%) (upper and lower limit difference / average value x 100%) was calculated. ○: The error is 5% or less, and reproducibility is good. △: The error is more than 5%, but is less than 10%, and is generally reproducible. ×: The error exceeds 10% and there is no reproducibility.

[0067] (stability) Under the measurement conditions, only the solvent (composition) was allowed to flow for 10 hours to evaluate the baseline stability. ○: The baseline was flat and stable. △: Baseline drift was observed, but there were almost no negative peaks or spike-like peaks. ×: Baseline drift, negative peaks, and spike-like peaks were observed.

[0068] Examples B-2 to B-6 and Comparative Examples B-7 to B-10 In Examples B-2 to B-6, the polymers, solvents (compositions 6 to 10), and measurement temperatures shown in Table 2 were changed, and GPC analysis was performed in the same manner as in Example B-1. The solubility of the polymers, reproducibility of the molecular weight, and baseline stability were similarly evaluated, and the results are shown in Table 2. In Comparative Examples B-7 to B-10, MPA containing no deterioration inhibitor and a general-purpose solvent were used as the solvent, and molecular weight measurement and evaluation were performed in the same manner as in Example B-1, and the results are shown in Table 2.

[0069] [Table 2]

[0070] From the results shown in Table 2, it can be seen that the alkoxy-N-substituted propanamide composition of the present invention contains an antidegradant, and therefore has excellent solubility for both general-purpose and poorly soluble polymers even at room temperature, and also has a stable baseline and good molecular weight reproducibility for long-term and high-temperature GPC analysis, and has high stability as a solvent. On the other hand, when a general-purpose solvent such as THF, DMF, or DMSO was used, the poorly soluble polymer could not be completely dissolved, and the molecular weight reproducibility was poor. Furthermore, when no antidegradant was contained, both the reproducibility and stability due to the deterioration of the alkoxy-N-substituted propanamide were reduced, and the composition could not be used suitably for long-term and high-temperature GPC analysis. The effect of the present invention is a synergistic effect due to the excellent dissolving power of the alkoxy-N-substituted propanamide and the stabilizing power of the antidegradant, and is not obtained by using only the alkoxy-N-substituted propanamide or by combining the antidegradant with other solvents.

[0072] Examples C-2 to C-5 and Comparative Examples C-6 to C-8 In Examples C-2 to C-5 and Comparative Examples C-6 to C-8, aqueous inkjet inks 2 to 8 were prepared in the same manner as in Example C-1 using the binder resins, pigment dispersions, solvents (compositions 12 to 15 were used in Examples C-2 to C-5, and water-soluble organic solvents were used in Comparative Examples C-6 to C-8) and various additives shown in Table 3. The storage stability, leveling properties, film resistance, and blocking resistance of the resulting inks 1 to 8 were evaluated by the following methods, and the results are shown in Table 3.

[0073] (Storage stability) The viscosity of the prepared aqueous inkjet inks 1 to 8 was measured at 25° C. using a viscometer (RE100L model, manufactured by Toki Sangyo Co., Ltd.), and then the ink was placed in an airtight container and stored at 60° C. for 30 days. After storage, the ink was removed and the viscosity was similarly measured at 25° C. The viscosity change rate [(viscosity after storage-viscosity before storage) / viscosity before storage] was calculated, and the storage stability was evaluated according to the following criteria. ◯: The viscosity change rate is less than ±10%. △: Viscosity change rate is ±10% or more and less than 20%. ×: The viscosity change rate is 20% or more.

[0074] (Leveling ability) The prepared aqueous inkjet inks 1 to 8 were used to perform solid printing on a polyvinyl chloride sheet with an untreated surface using an inkjet printer (Seiko I Infotec, IP-6500), and the leveling property of the printed matter was visually evaluated. ◯: No repellency was observed, and the print was even. △: A small amount of repellency is observed, and the print is somewhat uneven. ×: Repelling was observed, and the print was uneven.

[0075] (membrane resistance) The prepared aqueous inkjet inks 1 to 8 were used to print solid images on an untreated polyvinyl chloride sheet using an inkjet printer (Seiko I Infotec, IP-6500). The printed surface was rubbed back and forth 10 times with a cotton swab soaked in a 50% aqueous ethanol solution, and the condition of the printed surface was visually evaluated. ○: Peeling of the printed surface was less than 10%. △: Peeling of the printed surface was 10% or more and less than 50%. ×: Peeling of the printed surface was 50% or more.

[0076] (Blocking resistance) The prepared aqueous inkjet inks 1 to 8 were used to print solid images on a polyvinyl chloride sheet with no surface treatment using an inkjet printer (Seiko I Infotec, IP-6500), then the printed surface and the back surface were overlapped, and a load of 5 kg / cm2 was applied using a blocking tester, and the sheet was left for 24 hours under conditions of a temperature of 40°C and a humidity of 80%. After that, the printed matter for evaluation was removed and the presence or absence of show-through was confirmed. ○: The ink does not show through to the back side. △: The ink shows through slightly to the back side. ×: The ink shows through to the back side considerably.

[0077] [Table 3]

[0078] From the results shown in Table 3, the alkoxy-N-substituted propanamide composition of the present invention contains an anti-deterioration agent, and the inks of Examples C1 to C5 have excellent storage stability, and when used, the printing characteristics (leveling properties) are good, and the film resistance of the obtained printed matter is also good. On the other hand, the inks of Comparative Examples C6 to C8 changed viscosity significantly due to deterioration during storage, and the print leveling properties, film resistance of the obtained printed matter, and blocking resistance were also unsatisfactory.

[0079] Examples D-1 to D-8 and Comparative Examples D-9 to D-12 (Preparation of resist substrate) A film-coated glass (size 100 mm x 100 mm) manufactured by Hitachi Metals, Ltd. was used as the substrate, and naphthoquinone diazide / Novoltrac resin (HPR204, manufactured by Fujifilm Electronic Materials, Ltd.) was used as the resist. After the resist was applied onto the substrate, it was baked in an oven at 150°C for 15 minutes to prepare a resist substrate. The resist substrate was cut into 10 mm x 5 mm and used as a test piece for the peel test.

[0080] (Preparation of resist remover) The stripping agents used in Examples D-1 to D-8 and Comparative Examples D-9 to D-12 were prepared according to the compositions shown in Table 4 using the composition of the present invention, ion-exchanged water and a general-purpose organic solvent.

[0081] (peelability) The release agent and a test piece of resist substrate were placed in a sample bottle, and the test piece was immersed in the release agent. The time until the substrate in the liquid became colorless and transparent was measured while stirring at 40°C, and the evaluation was performed as follows.

A: No discoloration at all. △: Slight discoloration to pale blue. ×: Discoloration to blue was evident.

[0083] [Table 4]

[0084] From the above test results, it was confirmed that all the examples had good release properties and rust prevention properties. In the comparative examples, including the alkoxy-N-substituted propanamide (Comparative Example D-9) that did not contain an anti-degradant, neither release properties nor rust prevention properties were satisfactory.
