Abstract
The present invention relates to polycarbonate resins having a relaxation time of 2 seconds to 15 seconds at 250 ℃ and a residual phenol content of 3,000ppm or less.
Description
Technical Field
The present application claims priority and rights of korean patent application nos. 10-2022-0127550 and 10-2022-0141544, filed in the korean intellectual property office on day 5 of 2022 and day 28 of 2022, respectively, the entire contents of which are incorporated herein by reference.
The present specification relates to polycarbonate resins and methods of making the same.
Background
Optical glass or optical resin is used as an optical material for plastic optical products and optical films such as various lenses, prisms, optical disk substrates, and optical fibers. Although the optical glass has excellent heat resistance, transparency, dimensional stability and chemical resistance, the optical glass has problems of high material cost, poor moldability and low productivity.
Meanwhile, optical materials including optical resins can be mass-produced by injection molding. As the optical resin, a polycarbonate resin, a polyester-polycarbonate resin, or the like is used.
However, the optical resin has a disadvantage in that workability is deteriorated due to insufficient fluidity thereof. Therefore, it may be difficult to apply the optical resin to injection molding of an article requiring the aforementioned precision. In order to apply the resin to injection molding, it is necessary to raise the molding temperature, the mold temperature, etc., but the molding cycle becomes long, so that the molding cost increases, or the resin deteriorates, the color deteriorates, etc. during molding.
In order to solve this problem, examples of a method of improving the fluidity of a resin during molding of an optical material include a method of lowering viscosity, lowering weight average molecular weight, adding a low molecular weight oligomer, widening a molecular weight distribution, and the like, but excellent physical properties inherent to the resin such as heat resistance and impact resistance tend to deteriorate.
Accordingly, continuous efforts have been made to improve the processability while maintaining the advantages of the resin.

Advantageous effects
The polycarbonate resin according to one exemplary embodiment of the present specification has a shorter molecular relaxation time and a shorter cooling time in an injection mold than those of the polycarbonate resin in the related art, and thus has excellent processability. In addition, the polycarbonate resin has a small molecular weight drop during processing and has excellent processing stability.
By using the polycarbonate resin according to the exemplary embodiments of the present specification, an excellent optical lens, optical film, optical resin, optical fiber, or LED package having a small thickness can be obtained.
Detailed Description
Hereinafter, the present specification will be described in more detail.
The polycarbonate resin according to an exemplary embodiment of the present specification has a relaxation time of 2 seconds to 15 seconds at 250 ℃ and a residual phenol content of 3,000ppm or less.
An exemplary embodiment of the present specification provides a polycarbonate resin having a relaxation time of 1 second to 15 seconds at 250 ℃ and a residual phenol content of 3,000ppm or less, and comprising a first unit of chemical formula 1; a second unit of chemical formula 2; and a third unit of chemical formula 3.
According to one exemplary embodiment of the present specification, the polycarbonate resin has a relaxation time of 1 second to 15 seconds at 250 ℃. Or a relaxation time of 2 seconds to 15 seconds at 250 ℃. The relaxation time is specifically 2.5 seconds to 14.5 seconds, and more specifically 3.39 seconds to 14.2 seconds at 250 ℃.
When the polycarbonate resin satisfies the relaxation time at the temperature, the cooling time in the mold during injection molding is short due to the relatively short molecular relaxation time, the processing load is low, and the time between filling cycles is reduced, so that the relaxation time is reduced. Therefore, phenomena such as weld lines, cracks, warpage, birefringence, and starving during injection molding are reduced.
For the relaxation time according to an exemplary embodiment of the present specification, any method used in the art may be used without limitation, but the relaxation time is specifically measured using a mixed rheometer (HR-2) at 250 ℃ and 0.1Hz to 100 Hz. When the strain became 30% by applying a shear force at 250 ℃, and then removing the force, the viscoelastic behavior of the polymer occurring at high temperature (250 ℃) was measured by measuring the speed at which the applied shear force was recovered to 1Pa (=1N/m 2). The shearing force is maximally applied to the extent to which the molten polymer moves, and in this case, the stress is 100Pa or more. Thereafter, the stress was rapidly removed to measure the time taken to recover to 1Pa, and the time taken for the stress to recover to the above level means the relaxation time.
In one exemplary embodiment of the present specification, the important reason for the relaxation time is that problems such as physical damage due to weak external force may occur when the resin is cooled with residual stress during cooling of the injection molded product in a mold during injection molding of the resin. Therefore, when the relaxation time according to one exemplary embodiment of the present specification is provided, the residual stress is small, so that the problem during the resin injection molding is significantly reduced. However, the longer the relaxation time, the larger the residual stress is present, and thus physical damage may easily occur even if the external force is weak.
When the residual phenol content of the polycarbonate resin according to one embodiment of the present specification is 3,000ppm or less, the polycarbonate resin has a small molecular weight reduction during processing, and the polycarbonate resin has excellent processing stability. However, when the phenol content exceeds the above range, strength and physical properties are deteriorated due to a decrease in molecular weight of the polycarbonate resin, and problems such as cracking of an injection molded product during processing may occur. Therefore, the residual phenol content is preferably 3,000ppm or less.
According to an exemplary embodiment of the present specification, the polycarbonate resin has a residual phenol content of 3,000ppm or less. The residual phenol content of the polycarbonate resin is specifically 10ppm to 3,000ppm, 50ppm to 3,000ppm, and 100ppm to 3,000ppm, and more specifically 200ppm to 2,000ppm, 200ppm to 1,200ppm, or 470ppm to 720ppm.
In the present specification, the content (concentration) of the residual phenol can be calculated as follows. First, after 1.0g of pellets was dried and 1g of solid resin was dissolved in 12ml of Methylene Chloride (MC) and 18ml of methanol (MeOH), the resulting solution was filtered with a filter having a pore size of 0.2 μm, and then HPLC/UV was measured to calculate the content of residual phenol. ( Measurement wavelength: 200 μm HPCL, mobile phase A: acetonitrile, mobile phase B: h 2 O, column: CAPCELLPAK C18 (4.6 mm ID. Times.50 mm,5 μm), column temperature: 40 ℃, flow rate: 1 ml/min, injection volume: 5 μl, run time: for 10 minutes )

When the polycarbonate resin includes the first unit of chemical formula 1, the polycarbonate resin includes a relatively small isopropylidene group as compared to a large substituent such as fluorene, so that the process is economical and the possibility of processing defects is reduced because the cooling time in the mold during injection molding is short due to the short relaxation time of the polycarbonate resin, and the processability of the polycarbonate resin is excellent.

In one exemplary embodiment of the present description, the weight average molecular weight of the polycarbonate resin is 3,000g/mol to 500,000g/mol, preferably 5,000g/mol to 300,000g/mol, 7,000g/mol to 250,000g/mol, 8,000g/mol to 200,000g/mol. The weight average molecular weight of the polycarbonate resin is more preferably 9,000g/mol to 150,000g/mol, 10,000g/mol to 100,000g/mol, 12,000g/mol to 80,000g/mol, and 13,000g/mol to 60,000g/mol.
In one exemplary embodiment of the present invention, the polycarbonate resin has a number average molecular weight of 2,000 to 300,000g/mol, 3,000 to 200,000g/mol, 4,000 to 150,000g/mol, 4,500 to 100,000g/mol, preferably 5,000 to 80,000g/mol.
When the polycarbonate resin satisfies the above weight average molecular weight and number average molecular weight ranges, the polycarbonate resin may have optimal flowability and processability.
In the present specification, the weight average molecular weight (Mw) of the polycarbonate resin and the oligomer used in the preparation thereof can be measured by Gel Permeation Chromatography (GPC) using Polystyrene (PS) standards using Agilent 1200 series. Specifically, the weight average molecular weight can be measured using an Agilent 1200 series device using Polymer Laboratorie s PLgel MIX-B300 mm length columns, and in this case the measurement temperature is 40 ℃, the solvent used is Tetrahydrofuran (THF), and the flow rate is 1 mL/min. Samples of polycarbonate resin or oligomer were each prepared at a concentration of 10mg/10mL, then fed in an amount of 10 μl, and weight average molecular weight (Mw) values were derived using a calibration curve formed using polystyrene standards. In this case, nine types of polystyrene standard products having a molecular weight (g/mol) of 2,000/10,000/30,000/70,000/200,000/700,000/2,000,000/4,000,000/10,000,000 are used.
According to an exemplary embodiment of the present specification, the refractive index of the polycarbonate resin is 1.6 to 1.8 at 587 nm. The refractive index may preferably be 1.6 to 1.75, more preferably 1.6 to 1.72, and more preferably 1.660 to 1.669. When the resin satisfies the above refractive index, a thin and lightweight optical lens can be manufactured when the resin is applied to a molded article such as an optical lens.
In one exemplary embodiment of the present specification, the abbe number of the polycarbonate resin measured and calculated at wavelengths of 486nm, 587nm and 656nm may be 5 to 45. Preferably, the abbe number may be 10 to 25.
When the polycarbonate resin satisfies the above abbe number range, there are effects of reduced dispersion and increased sharpness when the resin is applied to molded articles such as optical lenses.
The Abbe number can be obtained from the following equations by specifically measuring refractive indices (nD, nF, and nC) at wavelengths D (587 nm), F (486 nm), and C (656 nm), respectively, at 25 ℃.
Abbe number= (nD-1)/(nF-nC)
The refractive index may be measured by a prism coupling method, and for example, SPA-3DR manufactured by SAIRON Technology Inc. may be used, but is not limited thereto.
The refractive index of the resin can be calculated by measuring the change in the amount of light reflected from the prepared sample, in which the resin was flattened by placing the slide on a heated plate of 200 c, using a prism coupler. When a prepared sample is brought into contact with a prism and then laser light is made incident on the prism, most of the incident laser light is totally reflected, but when a specific angle of incidence and conditions are satisfied, light is coupled because an evanescent field (EVANESCENT FIELD) is generated at the boundary surface. By measuring the angle at which coupling occurs (and as a result, the intensity of the light detected by the detector drops sharply), the refractive index of the film can be automatically calculated by the prism coupler from the parameters related to the polarization mode of the light and the refractive indices of the prism and the substrate.
In one exemplary embodiment of the present specification, the glass transition temperature (Tg) of the polycarbonate resin may be 90 to 200 ℃. The glass transition temperature may preferably be 100 ℃ to 190 ℃, 120 ℃ to 170 ℃, and 130 ℃ to 160 ℃, and even more preferably 141 ℃ to 142 ℃.
When the polycarbonate resin satisfies the above glass transition temperature range, the glass transition temperature is easily adjusted when the polycarbonate resin composition is prepared by mixing with a resin having excellent heat resistance and injection moldability and having a glass transition temperature different from the above range, so that the physical properties desired in the present specification can be satisfied.
The glass transition temperature (Tg) can be measured by a Differential Scanning Calorimeter (DSC). Specifically, the glass transition temperature can be measured from a graph obtained by: a sample of 5.5mg to 8.5mg of the polycarbonate resin was heated to 270 ℃ under a nitrogen atmosphere, and then scanned while the resin sample was heated at a heating rate of 10 ℃/minute during the second heating after cooling.
According to one exemplary embodiment of the present specification, the Melt Index (MI) of the polycarbonate resin is 5 to 150, specifically 10 to 100, and even more specifically 20 to 80 or 41 to 53. The above MI can be measured by a method used in the art, specifically, using a melt index meter (MI 2.2) manufactured by Goettfert co., ltd. The sample was dried in an oven at 120℃for 5 hours or more, the dried sample was put into a device and melted at a measurement temperature (260 ℃) for 5 minutes, and then the weight of the sample passing through a nozzle in 5 seconds was measured when a pressure of 2.16kg was applied, and converted into g/10 minutes units to calculate a Melt Index (MI).
When the polycarbonate resin has the aforementioned melt index, the polycarbonate resin exhibits characteristics suitable for injection molding due to maintaining proper fluidity.

For the polymerization of the resin according to the present specification, methods known in the art may be used.
Preferably, the polymerization is carried out by melt polycondensation.
In the melt polycondensation method, a composition for preparing a polycarbonate resin is used, a catalyst may also be applied as needed, and the melt polycondensation may be performed under heating and further under normal pressure or reduced pressure while removing by-products by transesterification. As the catalyst, materials commonly used in the art can be used.
Specifically, in the melt polycondensation method, it is preferable to cause the compound of chemical formula 1 a; a compound of formula 2 a; a compound of formula 3; and the polycarbonate precursor is melted in the reaction vessel and then reacted in a state where the byproduct compound is allowed to remain.
More specifically, in the melt polycondensation method, it is preferable to cause the compound of chemical formula 1 a; two or more compounds of formula 2 a; a compound of formula 3; and the polycarbonate precursor is melted in the reaction vessel and then reacted in a state where the byproduct compound is allowed to remain.
To allow the byproduct compounds to stay, the reaction apparatus may be shut down, or the pressure may be controlled by decreasing the pressure or increasing the pressure.
The reaction time of the process is 20 minutes or more and 600 minutes or less, preferably 40 minutes or more and 450 minutes or less, and more preferably 60 minutes or more and 350 minutes or less.
In this case, when the byproduct compound is distilled off immediately after production, the finally obtained resin has a small content of high molecular weight substances. However, when the byproduct compound is allowed to stay in the reaction vessel for a certain period of time, the finally obtained resin is obtained as a high molecular weight substance having a large content.
The melt polycondensation process may be carried out continuously or in a batch mode. The reaction apparatus for carrying out the reaction may be a vertical type equipped with a soken impeller, an anchor impeller, a maxbend impeller, a spiral belt impeller, or the like, may be a horizontal type equipped with a paddle blade, a grid blade, a spectacle blade, or the like, and may be an extruder type equipped with a screw. Further, in view of the viscosity of the polymer, it is desirable to perform using a reaction apparatus in which these reaction apparatuses are appropriately combined.
In the method for preparing a polycarbonate resin used in the present specification, the catalyst may be removed or deactivated after completion of the polymerization reaction to maintain thermal stability and hydrolytic stability. The method of inactivating the catalyst by adding an acidic substance known in the art may be preferably performed.
As the acidic substance, for example, esters such as butyl benzoate are preferably used; aromatic sulfonic acids such as p-toluene sulfonic acid; aromatic sulfonates such as butyl and hexyl p-toluenesulfonate; phosphoric acids, such as phosphorous acid, phosphoric acid, and phosphonic acid; phosphites, such as triphenyl phosphite, monophenyl phosphite, diphenyl phosphite, diethyl phosphite, di-n-propyl phosphite, di-n-butyl phosphite, di-n-hexyl phosphite, dioctyl phosphite and monooctyl phosphite; phosphates such as triphenyl phosphate, diphenyl phosphate, monophenyl phosphate, dibutyl phosphate, dioctyl phosphate and monooctyl phosphate; phosphonic acids, such as diphenylphosphonic acid, dioctylphosphonic acid, and dibutylphosphonic acid; phosphonates such as diethyl phenylphosphonate; phosphines, such as triphenylphosphine and bis (diphenylphosphino) ethane; boric acids, such as boric acid and phenylboric acid; aromatic sulfonates, e.g. tetrabutyl dodecylbenzene sulfonateA salt; organic halides such as stearic acid chloride, benzoyl chloride and p-toluenesulfonic acid chloride; alkyl sulfuric acids, such as dimethyl sulfuric acid; organic halides such as benzyl chloride; etc.
The acidic substance may be used in an amount of 0.1 to 5 parts by mol, preferably 0.1 to 1 part by mol, with respect to 100 parts by mol of the catalyst.
When the amount of the acidic substance is less than 0.1mol part, the effect of inactivation becomes insufficient, which is not preferable.

Examples
For each of the resin samples polymerized in the above preparation examples, the molecular relaxation time, high shear viscosity, residual phenol content, melt Index (MI), refractive index, and glass transition temperature were measured. Molecular relaxation times were measured using a mixed rheometer (HR-2) at 250℃and 0.1Hz to 100 Hz. When the strain was brought to 30% by applying a shear force at 250 ℃, and then the force was removed, the viscoelastic behavior of the polymer occurring at high temperature (250 ℃) was measured by measuring the speed at which the applied shear force was recovered to 1Pa (=1N/m 2). The shearing force is maximally applied to the extent to which the molten polymer moves, and in this case, the stress is 100Pa or more. Thereafter, the time taken for recovery to 1Pa was measured by rapidly removing the stress, and the results are shown in table 2 below.
The high shear viscosity was measured at 250℃and 10Hz to 63Hz by placing 2g to 5g of the resin sample into a mixing rheometer (discovery (HR-2)), and the results are shown in Table 2 below.
For residual phenol content, after 1g of solid resin was dissolved in 12ml of Methylene Chloride (MC) and 18ml of methanol (MeOH), the resulting solution was filtered by using a filter having a pore size of 0.2 μm, and then HPLC/UV was measured to calculate the residual phenol content, and it is shown in Table 2 below. ( Measurement wavelength: 200 μm HPCL, mobile phase A: acetonitrile, mobile phase B: h 2 O, column: CAPCELLPAK C18 (4.6 mm ID. Times.50 mm,5 μm), column temperature: 40 ℃, flow rate: 1 ml/min, injection volume: 5 μl, run time: for 10 minutes )
Melt Index (MI) was measured using a melt index meter (MI 2.2) manufactured by Goettfert inc. The resin sample was dried in an oven at 120℃for 5 hours or more, the dried sample was put into a device and melted for 5 minutes at a measurement temperature (260 ℃) and then the weight of the sample passing through the nozzle in 5 seconds was measured when a pressure of 2.16kg was applied and converted into g/10 minutes units to calculate a Melt Index (MI), and the melt index is shown in Table 2 below.
Differential Scanning Calorimeter (DSC) measurements to determine the glass transition temperature (Tg) of the resin. The glass transition temperature (Tg) is obtained on a graph obtained by: the resin samples were heated to 270 ℃ under a flow of N 2 mg to 8.5mg, cooled, and then scanned while being heated at a heating rate of 10 ℃/min during the second heating, and the glass transition temperatures (Tg) are shown in table 2 below.
The refractive index is measured by the prism coupler method. Refractive indices were measured at measurement wavelengths of 486nm, 587nm and 656nm, respectively, and the average values are shown in table 2 below. The refractive index measured at each of the wavelengths is the same.
TABLE 1
In table 1, the molar ratios of the monomers used in the polycarbonate resins used in the examples and comparative examples are shown.
TABLE 2
In table 2, tg means glass transition temperature, and MI means melt index.
In table 2, it can be seen that the resins of examples 1 and 2 (each of which is a polycarbonate resin according to one exemplary embodiment of the present specification) comprise a first unit, a second unit, and a third unit, and the polycarbonate resin has a relaxation time of 1 second to 15 seconds or 2 seconds to 15 seconds at 250 ℃ and a residual phenol content of less than 3,000 ppm. Specifically, the resins of examples 1 and 2 have relaxation times of 3.39 seconds to 14.2 seconds at 250 ℃ and residual phenol contents of 470ppm to 720 ppm.
In contrast, the polycarbonate resins of comparative examples 1 to 4 (which are resins each comprising the first unit, the second unit, or the third unit) and the polycarbonate resins of comparative examples 5 to 8 (which comprise only two of the first unit to the third unit) have a relaxation time of less than 1 second or more than 15 seconds and/or a residual phenol content of more than 3,000ppm at 250 ℃. When the relaxation time is less than 1 second, it can be determined that the viscosity is also low and the viscosity of the resin is low and the relaxation time is short, making it very difficult to process the resin, and when the relaxation time exceeds 15 seconds, it can be determined that the viscosity is high and the processing load increases due to the high viscosity and the long relaxation time of the resin, so that phenomena such as weld lines, cracks, warpage, birefringence, and starvation occur during injection molding.
In addition, when the residual phenol content exceeds 3,000ppm, many problems may be caused, such as deterioration of strength and physical properties due to a decrease in molecular weight of the polycarbonate resin, and cracking of the injection molded product during processing.
Although comparative examples 2,3, 6 and 8 have higher refractive indexes than examples 1 and 2, in comparative examples 2,3, 6 and 8, the relaxation time at 250 ℃ is less than 1 second or more than 15 seconds, making commercialization difficult because it is difficult to process the resin.
Further, although comparative examples 3 and 8 have higher refractive indexes than examples 1 and 2, in comparative examples 3 and 8, the residual phenol content exceeds 3,000ppm, so that many problems are caused, such as deterioration of strength and physical properties due to a decrease in molecular weight of the polycarbonate resin, and cracking of injection molded products during processing, resulting in deterioration of processing stability.
Thus, in the polycarbonate resin according to one exemplary embodiment of the present specification, since the relaxation time is 1 second to 15 seconds or 2 seconds to 15 seconds at 250 ℃ and the residual phenol content satisfies less than 3,000ppm, the molecular relaxation time is relatively short, so that the cooling time in the mold during injection molding is short and the processing load is low, and the time between filling cycles is reduced, resulting in a reduction in the relaxation time. In addition, since the residual phenol content is 3,000ppm or less, the decrease in molecular weight during processing is small. Therefore, phenomena such as weld lines, cracks, warpage, birefringence, and lack of glue are reduced during injection molding, and processing stability is excellent.
