Description

ANTISTATIC AGENT AND PLASTIC COMPOSITION COMPRISING THE SAME
Technical Field
The present invention relates to a salt formed of a pyrrolidinium derivative cation and a perfluoroalkylsulfone -based anion, and an antistatic agent comprising the same. Also, the present invention relates to a plastic composition comprising the same antistatic agent and a molded plastic article using the same plastic composition.
Background Art
In general, static electricity causes various problems during processing and use of various materials. Such static electricity causes collection of dirt and dust that adversely affect the quality of a finished product, resulting in contamination of the product. Static electricity is particularly problematic in the field of electronic industry, because modern electronic instruments are highly sensitive to discharge of static electricity. Meanwhile, dust agglomerate, formed by dust particles adhered to each other due to such static electricity, causes degradation in the quality of a molded plastic article. In particular, dust adhered onto a transparent molded article is problematic, and such adhesion of dust results in degradation in the quality of the molded article.
Build-up or formation of electrostatic charges causing static electricity can be inhibited by increasing electroconductivity of a material. Currently, the most popular means for preventing accumulation of electrostatic charges is a method for increasing electroconductivity via moisture adsorption. In general, prevention of static electricity via moisture adsorption can be accomplished by using a hygroscopic antistatic agent referred to as a humectant.
Antistatic agents may be classified into external antistatic agents and internal antistatic agents. The external antistatic agents may be applied onto the surface of a material requiring antistatic treatment. On the contrary, internal antistatic agents may be incorporated into the material. For example, in the case of a plastic article, an external antistatic agent is applied onto the molded plastic article after processing thereof, while an internal antistatic agent is added to a composition for molding the plastic article as an additive. Use of an internal antistatic agent is more cost-efficient, because there is no need for an additional step for applying the antistatic agent onto a molded plastic article after processing thereof. Such internal antistatic agents should have thermal stability sufficient for resisting a high polymer melting temperature corresponding to a range of 250 C ~400°C or higher. Additionally, since build-up or formation of static electricity is a phenomenon occurring on a surface, it is thought that an internal antistatic agent, capable of moving toward the surface of a material and of being distributed largely on the surface of the material, is more efficient.
Many antistatic agents among the known antistatic agents are surfactants that are neutral or have an ionic form in a natural state. However, because such surfactants increase the surface energy of a material, it is difficult to perform printing on the surface of the material with ink. In other words, such difficulty in printing with ink results from the fact that water molecules are attached onto the surface due to the surfactants. Therefore, there is a limitation in application of the surfactants when a printing process is required to be performed on the surface of a material.
Meanwhile, neutral antistatic agents with a low molecular weight show a high vapor pressure at a high temperature, for example, used in a polymer melting process. Hence, such neutral antistatic agents may evaporate during the polymer melting process, resulting in the loss thereof.
It is widely known in the art that a quaternary ammonium salt is a useful antistatic agent. Although the quaternary ammonium salt provides excellent antistatic property, it has low thermal stability and generally shows hygroscopic property. Therefore, the quaternary ammonium salt is problematic in that it cannot resist the high-temperature treating conditions needed for high-quality thermoplastic resins.
Additionally, it is known that metal salts of inorganic, organic and fluoroorganic anions are useful for a certain range of polymer compositions, as an antistatic agent. Considering the cost, toxicity and high affinity to water, alkali metal salts are the most widely used. However, most metal salts show insufficient thermal stability under the high- temperature treating conditions and have poor compatibility with weak polar polymers (e.g., polypropylene, polyester and polycarbonate). Such incompatibility may cause degradation in the transparency or other physical properties in a finished polymer article, and may provide insufficient antistatic effect.
Moreover, most metal salts are corrosive when used in metallic and electronic components. Thus, such metal salts are not suitable for certain applications wherein they are in contact with the surface of a metallic article. Also, known hydrophilic metal salts and quaternary ammonium salts still have all of the disadvantages of other humectant antistatic agents.
Therefore, it is necessary to provide a novel antistatic agent, which has high thermal stability, hydrophobicity, low volatile property, low corrosivity to metallic and electronic components, durability and excellent compatibility with polymers, and can impart excellent antistatic property to various insulation materials with a broad range of humidity levels.
Disclosure of the Invention
Therefore, the present invention has been made in view of the above-mentioned problems. It is an object of the present invention to provide an antistatic agent having excellent antistatic effect while not adversely affecting characteristics of plastic materials.
It is another object of the present invention to provide a salt that can be used as an antistatic agent and a plastic composition comprising the salt as an antistatic agent, particularly a transparent plastic composition.
According to an aspect of the present invention, there is provided a salt formed of a pyrrolidinium derivative cation and a perfluoroalkylsulfone-based anion. According to another aspect of the present invention, there is provided an antistatic agent comprising the above salt. According to still another aspect of the present invention, there is provided a plastic composition comprising the above antistatic agent.
The salt according to the present invention has high thermal stability, hydrophobicity, low volatile property, low corrosivity to metallic and electronic components, durability and excellent compatibility with polymers, and thus can be used as an antistatic agent capable of imparting excellent antistatic effect to various insulation materials.
Hereinafter, the present invention will be explained in more detail.

Particular examples of Rl and R2 include methyl, ethyl, propyl, butyl, pentyl, hexyl, isoropyl, isobutyl, tert-butyl, neopentyl, phenyl or benzyl. The pyrrolidinium derivative cation has excellent redox stability and is useful for the preparation of an ionic solution. Since the pyrrolidinium derivative cation is useful for the preparation of an ionic solution, it can form a salt with an anion, which otherwise shows low compatibility with weak polar substances (e.g., polycarbonate, polypropylene, etc.) and is not mixed well with such weak polar substances, particularly with a fluoroalkylsulfonate imide, and thus can improve the compatibility.

Since the perfluoroalkylsulfone -based anion does not show high compatibility with water and does not excessively increase the surface energy of an article, to which an antistatic agent containing the same anion is applied, it is possible to perform printing with ease on the surface of the article.
Among such perfluoroalkylsulfone-based anions, particular examples of the perfluoroalkylsulfonate anion represented by the above Formula 2 include: perfluorooctanesulfonate anion, perfluorobutanesulfonate anion, perfluorohexanesulfonate anion, or the like.
Meanwhile, particular examples of the perfluoroalkylsulfonate imide anion represented by the above Formula 3 include: bis(perfluorooctylsulfonate) imide anion, bis(perfluorobutylsulfonate)imide anion, bis(perfluorohexylsulfonate)imide anion, or the like.
The salt according to the present invention may be prepared by a known method. For example, the salt may be prepared by providing pyrrolidinium derivative cation and the perfluoroalkylsulfone-based anion individually, and then mixing both ions directly with each other. Otherwise, the salt may be prepared by reacting a compound containing the pyrrolidinium derivative cation or a salt thereof with a compound containing the perfluoroalkylsulfone-based anion or a salt thereof.
More particularly, the pyrrolidinium derivative cation may be prepared by the method of Handerson and Passerni disclosed in [Handerson and Passerni, Chem. Mater. 2004, 16, 2881-2885]. The perfluoroalkylsulfone-based anion may be a commercially available product.
The salt may be used as an antistatic agent. Particularly, the salt may be used as an antistatic agent for a plastic composition. According to a preferred embodiment of the present invention, the salt may be used in a plastic composition in an amount of 0.005 ~ 10 wt%, preferably of 0.3 ~ 2. wt%, based on the total weight of the plastic composition. If the salt is used in an excessively small amount, it is not possible to a desired antistatic effect. If the salt is used in an excessively large amount, it is not desirable in terms of cost efficiency and such an excessive amount of salt may adversely affect the physical properties of plastic materials containing the same salt.
Such plastic materials include thermoplastic materials. Particular examples of the thermoplastic materials include diphenol-based polycarbonate or copolycarbonate, polyacrylate, copolyacrylate, polymethacrylate, copolymethacrylate, polymethyl methacrylate, styrene polymers, styrene copolymers, styrene/acrylonitrile copolymers (SAN), transparent thermoplastic polyurethane, transparent polyolefm, transparent polypropylene, cyclic olefm-based polyolefin, polycondensation or copolycondensation products of terephthalic acid, polyethylene terephthalate (PET), copolyethylene terephthalate (CoPET) or glyol-modifϊed PET (PETG), or the like.
The antistatic salt according to the present invention may be useful particularly for polycarbonate or copolycarbonate. For example, the salt may be used desirably in non- halogenated polycarbonate or copolycarbonate having a molecular weight (Mw) of 500 -200,000, preferably 10,000 - 100,000, more preferably 15,000 -50,000.
Such polycarbonate may be prepared from a composition comprising diphenol and a carbonic acid derivative optionally with a chain terminating agent, a branching agent, etc. In brief, the polycarbonate may be prepared by a known method.
Preferred examples of the diphenol that may be used desirably for the preparation of polycarbonate include: 4,4'-dihydroxydiphenyl, 2,2,-bis-(4-hydroxyphenyl)propane, 2,4-bis-(4-hydroxyphenyl)-2-methylbutane, 1 , 1 -bis-(4-hydroxyphenyl)-p- diisopropylbenzene, 2,2-bis-(3-methyl-4-hydroxyphenyl)propane, 2,2-bis-(3-chloro-4- hydroxyphenyl)propane, bis-(3,5-dimethyl-4-hydroxyphenylmethane), 2,2-bis-(3,5- dimethyl-4-hydroxyphenyl)propane, bis-(3,5-dimethyl-4-hydroxyphenyl)sulfone, 2,4-bis- (3,5-dimethyl-4-hydroxyphenyl)-2-methylbutane, l,l-bis-(3,5-dimethyl-4- hydroxyphenyl)-p-diisopropylbenzene, 2,2-bis-(3,5-dichloro-4-hydroxyphenyl)propane, 2,2-bis-(3,5-dibromo-4-hydroxyphenyl)propane, 1 , 1 ,-bis-(4-hydroxyphenyl)-3,3,5- trimethylcyclohexane, or the like. Particularly preferred examples of the diphenol include 2,2-bis-(4-hydroxyphenyl)propane, 2,2-bis-(3,5-dimethyl-4-hydroxyphenyl)propane, 2,2- bis-(3,5-dichloro-4-hydroxyphenyl)propane, 2,2-bis-(3,5-dibromo-4- hydroxyphenyl)propane, 1 , 1 -bis-(4-hydroxyphenyl)cyclohexane, 1 , 1 -bis-(4- hydroxyphenyl)-3,3,5-trimethylcyclohexane, or the like. Particular examples of the branching agent include triphenol, trimesic acid
(trichloride), cyanuric acid trichloride, 3,3-bis-(3-methyl-4-hydroxyphenyl)-2-oxo-2,3- dihydroindole, or the like.
At least one additive for improving physical properties may be added, if desired. Particular examples of such additives include stabilizers, particularly thermal stabilizers (organic phosphonate or phosphine), a triphenyl phosphine-based demolding agent, glycerol fatty acid ester or tetramethanol methane, a flame retardant, a UV absorbing agent (hydroxybenzotriazol and hydroxytriazine), fillers, a foaming agent, a dye, a pigment, an optical bleaching agent, an ester exchange catalyst or a nucleating agent, or the like. Preferably, such additives may be used alone or in combination, and in an amount of about 5 wt% or less, preferably of 0.01 ~ 5 wt% based on the total weight of the plastic composition. According to the present invention, the salt and additives may be mixed with plastic materials in a conventional manner, for example, may be mixed with plastic materials before, during or after the polymerization of the materials. For example, a plastic material is provided first via polymerization in the form of a finely divided solid, powder, pellet, platelet or flake, and then the salt according to the present invention is added thereto, followed by molding to provide a molded plastic article. In other words, it is possible to produce a molded plastic article by simply adding an antistatic agent comprising the salt according to the present invention in the step for forming a molten solution useful for the manufacture of a molded plastic article. In this case, because the antistatic agent may be incorporated into the plastic article via simple mixing, the process for manufacturing the plastic article can be simplified.
Such molded plastic articles may be obtained by a conventional process, such as a high-temperature pressurization process, spinning process, extrusion process or an injection molding process. Particularly, the plastic composition comprising the salt according to the present invention may be used to manufacture a sheet or a film. It is possible to manufacture various sheets including single sheets, dual sheets and co- extruded sheets, having different levels of thickness.
Since the salt formed of the perfluorinated anion and pyrrolidinium cation according to the present invention shows a limited compatibility with water, it can show an antistatic effect in the absence of water absorption in the air. Moreover, the salt according to the present invention, which is free from moisture absorption, dose not increase the surface energy of a molded plastic article. Therefore, it is possible to improve the printability on the surfaces of molded plastic articles using the salt according to the present invention as an antistatic agent.
Meanwhile, conventional conductive antistatic agents affect light transmission characteristics of plastic articles, resulting in discoloration of the articles. On the contrary, the salt according to the present invention maintains the transparency while not affecting colors of plastic articles.

Best Mode for Carrying Out the Invention Reference will now be made in detail to the preferred embodiments of the present invention. It is to be understood that the following examples are illustrative only, and the scope of the present invention is not limited thereto.
<Preparation Example 1> Preparation of butyl methylpyrrolidinium perfluorobutanesulfonate (BMPPBS) Methyl pyrrolidine (97%, Aldrich Chemical), iodoethane (99%, Aldrich
Chemical), 1-iodopropane (99%, Aldrich Chemical) and 1-iodobutane (99%, Aldrich
Chemical) were used to provide butylmethylpyrrolidinium cation according to the method of Henderson and Passerni (Handerson and Passerni, Chem. Mater., 2004, 16, 2881-2885).
As an anion precursor, potassium perfluorobutanesulfonate (FR-2025™ available from 3M Co.) was used.
The butylmethylpyrrolidinium cation obtained as described above was mixed with potassium perfluorobutanesulfonate and the mixture was allowed to react to provide butylmethylpyrrolidinium perfluorobutanesulfonate (BMPPBS).
FIG. 5 shows NMR data for determining the presence of the butylmethylpyrrolidinium perfluorobutanesulfonate (BMPPBS) obtained as described above.
<Preparation Example 2> Preparation of butyl methylpyrrolidinium bis(tifluoromethanesulfonate)imide
Methyl pyrrolidine (97%, Aldrich Chemical), iodoethane (99%, Aldrich
Chemical), 1-iodopropane (99%, Aldrich Chemical) and 1-iodobutane (99%, Aldrich
Chemical) were used to provide butylmethylpyrrolidinium cation according to the method of Henderson and Passerni (Handerson and Passerni, Chem. Mater., 2004, 16, 2881-2885).
As an anion precursor, lithium bis(trifluoromethanesulfonate)imide (HQ-115™ available from 3M Co.) was used.
The butylmethylpyrrolidinium cation obtained as described above was mixed with lithium bis(trifluoromethanesulfonate)imide and the mixture was allowed to react to provide butylmethylpyrrolidinium bis(trifluoromethanesulfonate)imide.

<Preparation Example 3> Preparation of butyl methylpyrrolidinium bis(perfluoroethanesulfonate)imide Preparation Example 2 was repeated to provide butylmethylpyrrolidinium bis(perfluoro ethanesulfonate)imide, except that lithium bis(perfluoroethanesulfonate)imide (FC-130™ available from 3M Co.) was used as an anion precursor.
FIG. 7 shows NMR data for determining the presence of the butylmethylpyrrolidinium bis(perfluoro ethanesulfonate)imide.
Experimental Example 1> Thermal stability test
The following TGA (thermogravimetric analysis) and DSC (differential canning calorimetry) were performed to determine thermal stability of the salt according to the present invention. TGA means thermogravimetric analysis, and measures variations in the weight of a sample as a function of temperature to determine thermal changes, thermal stability and compositional ratio of the sample. In this example, 25.657mg of butylmethylpyrrolidinium perfluorobutanesulfonate (BMPPBS) obtained from Preparation Example 1 was used as a sample. As a control, 27.976mg of lithium bis(trifluoromethane sulfonate)imide (HQ- 115™ available from 3M Co.), one of the metal salts of perfluorolakylsulfonate imide currently used as an antistatic agent, was used. Each of the sample and the control was measured for variations in the weight by using a TGA instrument (TGA Q50 V6.2 Build 187), while increasing the temperature from 30 °C to 500 °C with a rate of 5 "C/min.
Additionally, the same sample and the control were subjected to DSC. DSC analyzes the heat flow generated upon the irradiation of light with a predetermined wavelength to a sample. During the analysis, heat quantity (dQ/dt) flowing through the sample is measured while varying the temperature. In this example, the salt was measured for its melting point by using a differential scanning calorimeter with a temperature ramp of 20 C/min. The peak point in the melting transition of the sample was regarded as the melting point (Tm) of the sample. When multiple melting transitions occurred, the peak related to the melting transition showing the largest area was regarded as the melting point.
TGA results of BMPPBS obtained from Preparation Example 1 are shown in FIG. 1, and TGA results of lithium bis(trifluoromethaesulfonate)imide (HQ-115™), as a control, are shown in FIG. 2. As can be seen from FIGs. 1 and 2, both of the sample and the control are stable at a temperature lower than 300 C , and are decomposed at a temperature higher than 350 C . Therefore, it can be seen that the salt for antistatic agent according to the present invention is stable at a temperature where plastic materials melt.
Meanwhile, DSC results of BMPPBS obtained from Preparation Example 1 are shown in FIG. 3, and DSC results of lithium bis(trifluoromethanesulfonate)imide (HQ- 115™) are shown in FIG. 4. As shown in FIG. 4, lithium bis(trifluoromethanesulfonate)imide (HQ-115™) melts at a temperature of 231 C , while BMPPBS melts at a temperature lower than 100°C . This indicates that BMPPBS can be decomposed into its cation and anion with ease. Hence, BMPPBS can be mixed easily with a molten solution of plastic materials by virtue of the aforementioned characteristics. Particularly, perfluoroalkane -based sulfonate has excellent contactablity with a weak polar polymer chain, and thus can be incorporated easily into a polymer chain structure.
<Examples 1 ~ 3 and Comparative Examples 1 ~ 3>
Polycarbonate films were produced according to the compositional ratio as shown in the following Table 1. Particularly, polycarbonate flake and an antistatic agent were introduced into a hopper, each in the amount as shown in Table 1, the materials were mixed and molten, and then the molten mixture was extruded via an extruder to provide polycarbonate films. Since the salt according to the present invention has excellent thermal stability, it is possible to provide molded polycarbonate articles by a simple process comprising the steps of mixing the salt with polycarbonate flake and melting the mixture, followed by molding.

<Experimental Example 2> Test for Static Electricity- Dust Adhesion Test
To perform a dust adhesion test, each of the polycarbonate films according to
Examples 1 ~ 3 and Comparative Examples 1 ~ 3 was exposed to an artificial environment having dust floating therein. For this, dust (coal dust/active carbon 2Og) was packed into a
2L beaker equipped with a magnetic stirring bar to a height of about lcm, and the dust was allowed to float in the atmosphere by using the magnetic stirring bar. After terminating the operation of the stirring bar, each sample was exposed to the dust-containing environment for seven seconds to cause the dust to adhere onto the film. Dust adhesion was evaluated visually. Sheets having dust agglomerate were expressed by the sign of (-), and sheets having no dust as determined visually were expressed by the sign of (+). The results are shown in the following Table 2.
Experimental Example 3> Measurement of Surface Resistance
To evaluate the antistatic effect of the salt according to the present invention, measurement of surface resistance was carried out.
Most antistatic agents show antistatic effect by dissipating electrostatic charges when electrostatic charges are formed or built up. Thus, efficiency of an antistatic agent is generally evaluated by measuring the surface conductivity.
The test performed in this example is based on ASTM Standard D-257, "D. C. resistance or Conductance of Insulating Materials." Surface resistance was measured by using a broad-range resistance measuring device equipped with the model 803B probe
(ETS Model No. 872, available from ElectroTech Systems, Inc., Glenside, Pennsylvania,
USA). The device allows application of an external voltage of 100V across two concentric ring-like electrodes, to which a flat test material is contacted, and provides surface resistance values in Ω/square units.
Each of the polycarbonate films according to Examples 1 ~ 3 and Comparative Examples 1 ~ 3 was measured for the surface resistance three times, and then the average value was calculated. The results are shown in the following Table 2.
Figure imgf000013_0001
As can be seen from the above results, the salt according to the present invention can reduce the surface resistance of a plastic substrate, and thus can provide an excellent antistatic effect.
Industrial Applicability
As can be seen from the foregoing, the salt according to the present invention, which is formed of a pyrrolidinium derivative cation and a perfluoroalkylsulfone-based anion, shows an excellent antistatic effect when used as an antistatic agent. The salt according to the present invention does not show high compatibility with water, and thus allows a plastic article to be amenable to a printing process with ink. Particularly, the salt according to the present invention shows excellent miscibility with a plastic substrate, and thus is useful as an antistatic agent for plastic articles. Additionally, the salt according to the present invention does not affect the light transmission characteristics of articles containing the salt, and thus can maintain the transparency of the articles while not affecting the colors of the articles.
While this invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiment and the drawings. On the contrary, it is intended to cover various modifications and variations within the spirit and scope of the appended claims.
