Description

複合導電性高分子組成物、その製造方法、当該組成物を含有する溶液、および当該組成物の用途Composite conductive polymer composition, production method thereof, solution containing the composition, and use of the composition
　本発明は、複合導電性高分子組成物、その製造方法、当該組成物を含有する溶液、および当該組成物の用途に関し、更に詳細には、アニリン、チオフェン、ピロール等の芳香族系、複素環系化合物をモノマー構成成分とするπ共役系高分子に溶剤可溶性を付与するために、高分子乳化剤をドーピングした複合導電性高分子組成物、その製造方法、当該組成物を含有する溶液、および当該組成物の色素増感型太陽電気用電極や帯電防止フィルムなどへの利用に関する。 The present invention relates to a composite conductive polymer composition, a production method thereof, a solution containing the composition, and a use of the composition. More specifically, the present invention relates to an aromatic system such as aniline, thiophene, and pyrrole, and a heterocyclic ring. In order to impart solvent solubility to a π-conjugated polymer having a monomer compound as a monomer component, a composite conductive polymer composition doped with a polymer emulsifier, a production method thereof, a solution containing the composition, and the The present invention relates to the use of the composition for a dye-sensitized solar electrode or an antistatic film.
　π共役系高分子における高い導電性付与にはドーパントによるドーピングが必須である。しかし、本来π共役が発達した高分子は、高分子鎖の平面性が高く、π結合の親和力による高分子鎖間の結晶性（スタッキング性）が高い構造となっている。しかも、ドーパントにより、ドーピングされたπ共役系高分子は、更に平面性およびπ共役による親和力が高くなり、スタッキング性が更に顕著となる。このため、π共役系高分子の溶解（熱または溶剤による）と電気伝導度の両立は難しい課題であった。 Doping with a dopant is essential for imparting high conductivity in a π-conjugated polymer. However, a polymer in which π conjugation has originally developed has a structure in which the polymer chain has high planarity and crystallinity (stacking property) between polymer chains due to the affinity of π bond. Moreover, the π-conjugated polymer doped with the dopant has higher planarity and higher affinity due to π-conjugation, and the stacking property becomes more remarkable. For this reason, it is a difficult problem to achieve both the dissolution (by heat or solvent) of the π-conjugated polymer and the electrical conductivity.
　そこで、π共役系高分子の側鎖へアルキル基やアルコキシル基等を導入した高分子が提案されているが（特許文献１）、実際に十分導電体と言える１０のマイナス５乗ｓ・ｍ以下まで電気伝導度を上げるためには、ドーピングが必要となる。そして、このドーピングを行えば、その結果、導電性高分子の平面性発達とπ共役親和性の発達により、十分な溶剤可溶性が得られなくなってしまうという問題があった。 Thus, a polymer in which an alkyl group, an alkoxyl group, or the like is introduced into the side chain of a π-conjugated polymer has been proposed (Patent Document 1). In order to increase the electrical conductivity up to, doping is necessary. If this doping is performed, there is a problem that sufficient solvent solubility cannot be obtained due to the development of the planarity of the conductive polymer and the development of π-conjugate affinity.
　導電性高分子の利用を考えた場合、取り扱いの容易さからは、溶剤による溶解や、熱による溶融が可能で、且つ成型成膜後は十分な電気伝導度を有する自立膜や自立形成体が得られることが望まれており、従来、これら導電性ポリマーの使用の際には、直接導電性を付与したい基体上で電解重合や蒸気暴露による重合体膜の成膜、酸化剤と導電性ポリマー前躯体モノマー溶液に浸漬後加熱等による薄膜重合等を行い、その後、得られた重合体膜にドーピングする等の処理を行っている。 When considering the use of conductive polymers, from the viewpoint of ease of handling, it is possible to use a self-supporting film or a self-supporting body that can be dissolved by a solvent or melted by heat, and has sufficient electrical conductivity after molding. Conventionally, when these conductive polymers are used, a polymer film is formed by electrolytic polymerization or vapor exposure on a substrate to which direct conductivity is desired, an oxidizing agent and a conductive polymer. After being immersed in the precursor monomer solution, a thin film polymerization or the like is performed by heating or the like, and then a treatment such as doping of the obtained polymer film is performed.
　しかしこの場合、電解重合では基体が半導体若しくは導電体である必要が有り、また、電解液への耐腐食性も求められる為、使用できる基体が制限される。また、直接蒸気による薄膜重合では、重合場となる薄膜に酸化剤を均質に存在させる必要があり、成膜制御の面では十分と言えず、また、これら手法で用いられるポリマーコンデンサー用途では、表面積を大きくする為に微細な凹凸を形成しており、十分均質な表面への導電性ポリマー形成は困難であった。 However, in this case, the electrolytic polymerization requires the substrate to be a semiconductor or a conductor, and corrosion resistance to the electrolytic solution is also required, so that usable substrates are limited. In addition, in thin film polymerization using direct vapor, it is necessary to make the oxidant homogeneously present in the thin film that becomes the polymerization field, which is not sufficient in terms of film formation control. In order to increase the thickness, fine irregularities were formed, and it was difficult to form a conductive polymer on a sufficiently homogeneous surface.
　そこで、導電性ポリマーを有機溶媒に溶解させる試みがなされ、そのための手段がいくつか提案されている。特許文献２には、３,４－ジ置換チオフェンを無機第２鉄塩類および酸化剤を用いて重合させるポリ（３,４ージ置換チオフェン）の製造方法が開示されており、また、特許文献３には、主に繰り返しチオフェン単位を有するポリマーＴ および少なくとも１ 個の他のポリアニオンポリマーＰ を有する水分散性粉末が開示されている。しかし、特許文献２の方法は、粉末物を得る手法若しくは直接対象被着体表面で酸化重合する方法であって、本手法では得られた重合物を溶剤若しくは水等へ溶解させることは不可能であり、また特許文献３のものも、水分散性良好な分散体でしかなく、有機溶剤に対し分子可溶するようなものではない。 Therefore, attempts have been made to dissolve the conductive polymer in an organic solvent, and several means for that purpose have been proposed. Patent Document 2 discloses a method for producing poly (3,4-disubstituted thiophene) in which 3,4-disubstituted thiophene is polymerized using an inorganic ferric salt and an oxidizing agent. 3 discloses a water dispersible powder having a polymer T having predominantly repeating thiophene units and at least one other polyanionic polymer P. However, the method of Patent Document 2 is a method for obtaining a powdered material or a method for performing oxidative polymerization directly on the surface of the target adherend, and it is impossible to dissolve the polymer obtained in this method in a solvent or water. Also, the one of Patent Document 3 is only a dispersion having good water dispersibility, and is not such that it is molecularly soluble in an organic solvent.
　また、より直接的な溶剤ナノ分散化の手段として各種検討がされており、特許文献４では、本質的に溶剤に可溶しないポリアニリンを、ナノサイズレベルまで粉砕微粉化しポリアニリンおよび溶剤に親和性の高いＳＤＳ（ドデシルベンゼンスルホン酸）やＰＴＳ（パラトルエンスルホン酸）等のスルホン酸アニオン乳化剤を分散剤として用いながら溶剤に共分散させ、ナノレベルでの微分散体溶液の提供を開示しているが、実質的に溶剤に可溶している訳ではないので、塗工膜の表面は凸凹としており、また、ポリアニリンのみでの自立膜（均質膜ともいう。単独でピンホールなどを生じずに膜化したものを意味する）とすることは出来ないため、バインダーなどと組み合わせない限りコーティング後に膜化させることは不可能である。 Further, various studies have been made as a more direct means for solvent nanodispersion. In Patent Document 4, polyaniline, which is essentially insoluble in a solvent, is pulverized and pulverized to a nano-size level and has an affinity for polyaniline and the solvent. Although a high sulfonic acid anion emulsifier such as SDS (dodecylbenzenesulfonic acid) or PTS (paratoluenesulfonic acid) is used as a dispersant, it is disclosed to provide a fine dispersion solution at a nano level. The surface of the coating film is uneven because it is not substantially soluble in a solvent, and is also a self-supporting film made of only polyaniline (also called a homogeneous film. It is impossible to form a film after coating unless it is combined with a binder or the like.
　更に、特許文献５では、分子量２,０００～５００,０００の範囲の分子量を有する、ポリスチレンスルホン酸のポリ陰イオンの存在下で酸化化学重合されたポリチオフェンと、分子量２,０００～５００,０００の、ポリスチレンスルホン酸由来のポリ陰イオンを水または水と水混和性有機溶媒の混合溶媒中に含んでなるポリチオフェンの溶液が開示されている。 Furthermore, in Patent Document 5, polythiophene having a molecular weight in the range of 2,000 to 500,000 and oxidized and chemically polymerized in the presence of a polyanion of polystyrene sulfonate and a molecular weight of 2,000 to 500,000 are disclosed. A solution of polythiophene comprising a polyanion derived from polystyrene sulfonic acid in water or a mixed solvent of water and a water-miscible organic solvent is disclosed.
　この特許文献は、ポリスチレンスルホン酸（ＰＳＳ）と酸化剤共存下での酸化重合で、水またはアルコール溶剤へ溶解または分散可能なポリ（エチレンジオキサイド置換チオフェン）（ＰＥＤＯＴ）の製造方法の提案であるが、ここで得られるＰＥＤＯＴ／ＰＳＳは水に分散はされているが、完全な溶解はされておらず、部分的なＰＥＤＯＴ間のスタッキングを抑えることは難しく、導電性ポリマーを溶解するには不十分なものであった。 This patent document proposes a method for producing poly (ethylene dioxide substituted thiophene) (PEDOT) that can be dissolved or dispersed in water or an alcohol solvent by oxidative polymerization in the presence of polystyrene sulfonic acid (PSS) and an oxidizing agent. However, although the PEDOT / PSS obtained here is dispersed in water, it is not completely dissolved, it is difficult to suppress stacking between partial PEDOTs, and it is difficult to dissolve the conductive polymer. It was enough.
　更にまた、特許文献６には、疎水性の大きなアニオン性界面活性剤の存在下において、アニリン、もしくはアニリン誘導体を、有機酸や無機酸を含む溶媒中で酸化重合して析出、単離、精製した後、水と混和しない有機溶媒で抽出して有機溶液を形成することが開示されている。 Furthermore, Patent Document 6 discloses precipitation, isolation, and purification by oxidative polymerization of aniline or aniline derivatives in a solvent containing an organic acid or an inorganic acid in the presence of a highly hydrophobic anionic surfactant. And then extracting with an organic solvent immiscible with water to form an organic solution.
　しかし、この特許文献で使用されている乳化剤は低分子スルホン酸系であり、重合前にアニリンを塩酸塩化し、その後スルホン酸系乳化剤によりアニリン塩置換を行っているが、実際には十分な塩交換は起こり難く、また、本特許文献の合成法により得られるポリアニリンは実際には溶剤に溶解せず、微分散状態の溶剤分散液しか得られないという問題がある。また、アニリンに対して等量モル以上のスルホン酸系乳化剤が使用される為、実質ドープされた乳化剤以外の乳化剤が５０％以上残存し、使用に当たっては、これら乳化剤を取り除くことが必要であり、この為には洗浄工程が煩雑であるという問題がある。更には、低分子乳化剤では溶剤への溶解付与効果と、ポリアニリンのスタックを抑止する効果を１分子の設計として導入することは非常に困難であり、仮に一時的に溶剤に溶解したポリアニリンの状態でも直ぐにスタック（ＰＡＮＩの結晶化）による微凝集が発生してしまうという問題がある。 However, the emulsifier used in this patent document is a low molecular sulfonic acid type, and aniline is converted to hydrochloric acid before polymerization, and then aniline salt substitution is performed with the sulfonic acid type emulsifier. The exchange hardly occurs, and the polyaniline obtained by the synthesis method of this patent document does not actually dissolve in the solvent, and there is a problem that only a finely dispersed solvent dispersion can be obtained. Moreover, since sulfonic acid-based emulsifiers in an equimolar amount or more with respect to aniline are used, 50% or more of emulsifiers other than substantially doped emulsifiers remain, and in use, it is necessary to remove these emulsifiers, For this purpose, there is a problem that the cleaning process is complicated. Furthermore, it is very difficult to introduce the effect of imparting solubility in a solvent and the effect of inhibiting the stacking of polyaniline as a single molecule design with a low molecular emulsifier, and even in the state of polyaniline temporarily dissolved in a solvent. There is a problem that fine aggregation due to stacking (PANI crystallization) occurs immediately.
　また更に特許文献７では、（Ａ）スルホン酸官能基とラジカル重合性官能基とを有するモノマーおよび（Ｂ）アニリンまたはその誘導体からなるモノマー を水もしくは有機溶剤に溶解した溶液を乳化し、（Ｂ）のモノマー中に（Ａ）のモノマーに由来するスルホン酸構造を導入した後、重合開始剤下記の共存下に（Ａ）および（Ｂ）のモノマーを重合して、（Ｂ）の重合体と（Ａ）の重合体とが絡み合った状態の導電性ポリマーを作製する方法が開示されている。 Furthermore, in Patent Document 7, a solution in which (A) a monomer having a sulfonic acid functional group and a radical polymerizable functional group and (B) a monomer soot made of aniline or a derivative thereof is dissolved in water or an organic solvent is emulsified. ), The sulfonic acid structure derived from the monomer (A) is introduced into the monomer, the polymerization initiator (A) and the monomer (B) are polymerized in the coexistence of the following, and the polymer (B): A method for producing a conductive polymer in an intertwined state with the polymer (A) is disclosed.
　しかし、この特許文献の方法では、水系酸化剤兼ラジカル開始剤として過硫酸アンモニウム塩を使用している為、実際には本明細に書かれているような理想的なビニル系ポリマーとポリアニリンの相互網目状構造は困難である。従って、この特許文献方法では、実際には、ＰＡＮＩを含まないビニルポリマーが相当数存在したり、逆にビニルポリマーに取り込まれないドープモノマーがＰＡＮＩ中で存在したりして、非常に不均一且つ不安定な物となるという問題がある。 However, in the method of this patent document, an ammonium persulfate salt is used as an aqueous oxidant / radical initiator, so that an ideal vinyl polymer and polyaniline mutual network as described in this specification is actually used. The structure is difficult. Therefore, in this patent document method, there are actually a large number of vinyl polymers that do not contain PANI, and conversely, dope monomers that are not incorporated into the vinyl polymer exist in PANI. There is a problem of becoming unstable.
　例えば特許文献８には、実質的に水と混和しない有機溶剤に溶解している、(a)プロトネーションされた置換または未置換ポリアニリン複合体、および(b)フェノール性水酸基を有する化合物を含む導電性ポリアニリン組成物が開示されている。 For example, Patent Document 8 discloses a conductive material containing (a) a protonated substituted or unsubstituted polyaniline complex and (b) a compound having a phenolic hydroxyl group dissolved in an organic solvent that is substantially immiscible with water. A functional polyaniline composition is disclosed.
　しかしこの特許文献では、溶剤／水／モノマー／乳化剤の重合場において、水溶性酸化剤を用いてポリアニリンの合成を行っている為、本質的には水溶アニリンモノマーが重合しながら乳化剤を介してトルエンに分散する系でポリアニリンとなり、実質トルエン以外に水に対して幾分溶解するような溶剤への展開は不可能である。また、本特許文献の発明で、実際に使用しているジイソオクチルスルホコハク酸ナトリウム（ＡＯＴ）では、ポリアニリンのスタッキングを十分に抑制することが出来ない為、フェノール類（クレゾール）等の併用が必須となっている。これは、明細書の記載は十分ではないが非特許文献１に記載されている技術であり、ポリアニリン被膜中におけるドナー強度の調整により、フェノール性化合物の親和性が顕著にあり、ポリアニリン被膜における導電性向上に有用であると開示されている。これは、つまりフェノール類の様にトルエンに対し溶解性が良好でポリアニリンへの相溶性が良好な不揮発性添加剤を混合することで、乾燥塗膜の導電性を向上させるだけでなく、トルエン可溶中のポリアニリン同士のスタックをフェノール類が抑制していると考えられ、これら添加剤が無い場合はＡＯＴのような立体障害性でのポリアニリンの結晶性制御では十分な可溶性の安定化が不可能であり、このことは本発明者らの追試でも確認されている。 However, in this patent document, since polyaniline is synthesized using a water-soluble oxidant in a solvent / water / monomer / emulsifier polymerization field, essentially water-soluble aniline monomer is polymerized while toluene is passed through the emulsifier. It is impossible to develop into a solvent that becomes polyaniline in a system in which it is dispersed in water and is somewhat soluble in water other than toluene. In addition, the sodium diisooctylsulfosuccinate (AOT) actually used in the invention of this patent document cannot sufficiently suppress the stacking of polyaniline. Therefore, it is essential to use phenols (cresol) together. It has become. This is a technique described in Non-Patent Document 1, although the description is not sufficient, and by adjusting the donor strength in the polyaniline coating, the affinity of the phenolic compound is remarkable, and the conductivity in the polyaniline coating is It is disclosed that it is useful for improving the performance. In other words, by mixing non-volatile additives that have good solubility in toluene and good compatibility with polyaniline, such as phenols, not only improve the conductivity of the dried coating, but also allow toluene. It is thought that phenols suppress the stack of polyaniline in solution, and in the absence of these additives, it is impossible to stabilize the solubility sufficiently by controlling the crystallinity of polyaniline with steric hindrance like AOT This has been confirmed by the inventors' additional test.
　一方、導電性ポリマー組成物を用いた用途として、色素増感型太陽電池用対極や帯電防止フィルムがある。特許文献１０には、透明導電層を設けられたプラスチックフィルムに導電性高分子層を設けてなる色素増感型太陽電池の対極が開示されている。 On the other hand, as an application using the conductive polymer composition, there are a counter electrode for a dye-sensitized solar cell and an antistatic film. Patent Document 10 discloses a counter electrode of a dye-sensitized solar cell in which a conductive polymer layer is provided on a plastic film provided with a transparent conductive layer.
　しかし、この特許文献では、導電性高分子を含む分散液を塗布し、溶媒を除去して導電性高分子層を形成しているが、導電性高分子は微粒子の分散膜であるため、透明導電層に対する密着性が悪く、予めプラズマ処理などを行い透明導電層の表面エネルギーを高める必要がある。また、この特許文献の実施例において、分散剤にポリスチレンスルホン酸を用いていることが記載されているが、この場合は導電性高分子のドープに寄与しないフリーのスルホン酸が存在することとなり、溶媒は水溶液となる為にフィルム基板上に塗工する場合に溶媒とフィルム基板表面の選択性が非常に大きく、導電性高分子塗膜の不均一性に由来するピンホールが発生し易いこと、残存スルホン酸基により塗膜の極性が高いことから電解質溶液で一般的に使用されるアセトニトリルやイオン性液体等への耐久性が悪く塗膜の剥がれが発生し易いこと、等を原因として透明導電膜が電解液中のヨウ素により腐食される問題が挙げられることから、対極としての長期的な安定性に問題があることで白金対極を置き換えるには不十分であった。 However, in this patent document, a dispersion containing conductive polymer is applied and the solvent is removed to form a conductive polymer layer. However, since the conductive polymer is a dispersion film of fine particles, it is transparent. Adhesion to the conductive layer is poor, and it is necessary to increase the surface energy of the transparent conductive layer by performing plasma treatment or the like in advance. In addition, in the examples of this patent document, it is described that polystyrene sulfonic acid is used as the dispersant, but in this case, there is free sulfonic acid that does not contribute to the doping of the conductive polymer, Since the solvent becomes an aqueous solution, the selectivity between the solvent and the film substrate surface is very large when applied on the film substrate, and pinholes derived from the non-uniformity of the conductive polymer coating film are likely to occur. Transparent conductivity due to the high polarity of the coating film due to residual sulfonic acid groups, and poor durability to acetonitrile and ionic liquids commonly used in electrolyte solutions, and the tendency of the coating film to peel off. Since the problem is that the membrane is corroded by iodine in the electrolyte, the long-term stability as a counter electrode is insufficient to replace the platinum counter electrode.
　また、特許文献１１には、ポリチオフェン系化合物、酸性ポリマーおよび糖アルコールを含有する帯電防止材料を熱可塑性樹脂フィルムに塗布した帯電防止フィルムが開示されている。 Further, Patent Document 11 discloses an antistatic film in which an antistatic material containing a polythiophene compound, an acidic polymer, and a sugar alcohol is applied to a thermoplastic resin film.
　しかし、この特許文献では、帯電防止材料として糖アルコールを必須成分とすることにより、得られる帯電防止フィルムの透明性や帯電防止性は良好であるが、ポリチオフェン系化合物へのドーピング剤としてポリスチレンスルホン酸などの酸性ポリマーのみを使用しているため、帯電防止膜が経時で吸湿することによって、密着性および帯電防止性が低下する問題がある。 However, in this patent document, by using sugar alcohol as an essential component as an antistatic material, the antistatic film obtained has good transparency and antistatic properties, but polystyrene sulfonic acid is used as a doping agent for polythiophene compounds. Since only an acidic polymer such as the above is used, the antistatic film absorbs moisture over time, and there is a problem that adhesion and antistatic properties are lowered.

　そこで、本発明は、溶剤への溶解性に優れ、自立膜、すなわち、単独でピンホールなどの生じない均質な膜若しくは成形体となる導電性高分子組成物およびその製造方法等を提供することを課題としている。 Accordingly, the present invention provides a conductive polymer composition that is excellent in solubility in a solvent and is a self-supporting film, that is, a homogeneous film or a molded body that does not cause pinholes alone, and a method for producing the same. Is an issue.
　本発明者らは、上記課題を解決すべく前記の先行技術を追試し検討した結果、＜１＞π共役系高分子の重合場では十分な電解資質溶媒を使用し、酸化が進むアニオン場を安定且つ均一系を与える必要が有ること、＜２＞重合成長中のπ共役系高分子のスタッキングを制御し且つ安定なモノマー供給を与える為の場が必要なこと、＜３＞これら重合成長場でのπ共役系ポリマーへのドーピングが積極的に進むこと、＜４＞これらドーピングの過程で水等の初期重合場電解資質溶媒から析出可能であること、＜５＞重合後のπ共役系高分子が何らかの立体的分子障害により主鎖骨格のスタッキングが抑止されていること、＜６＞これら立体障害性因子がこの物自身で結晶性を有しておらず、且つ溶剤や熱などでの溶融が可能であること等の要素が導電性ポリマー合成の初期から精製、溶剤への再溶解に必要である事実が明確になった。 As a result of further examination of the above prior art in order to solve the above problems, the present inventors have found that an anionic field in which oxidation is progressed by using a sufficient electrolytic solvent in the polymerization field of <1> π-conjugated polymer. It is necessary to provide a stable and homogeneous system, <2> a field for controlling the stacking of π-conjugated polymers during polymerization growth and providing a stable monomer supply, <3> these polymerization growth fields <4> Precipitation from an initial polymerization field electrolyte solvent such as water in the process of doping, <5> High π-conjugated system after polymerization Stacking of the main chain skeleton is suppressed due to some steric molecular hindrance, and <6> these steric hindrance factors do not have crystallinity themselves, and are melted by a solvent or heat. Such as being possible Purification from the initial conductive polymer synthesis, the fact is required to re-dissolution in a solvent became clear.
　そこで、本発明者らは更に検討した結果、特定のモノマーを共重合した高分子化合物を、π共役系高分子の重合時に添加剤として使用すると、乳化剤としての重合場を均一状態化する機能に加えて、ドープ材としての機能を発揮すると共に、π共役系高分子への適度な立体障害性を有するために、特定の溶剤への可溶性に優れた複合導電性高分子組成物が得られることを見いだした。また、本発明者らは前記の複合導電性高分子組成物が、色素増感型太陽電気用対極や帯電防止フィルムなどに利用できることを見いだし、本発明の完成に至った。 Therefore, as a result of further studies, the present inventors have found that when a polymer compound copolymerized with a specific monomer is used as an additive during the polymerization of a π-conjugated polymer, the function of making the polymerization field as an emulsifier uniform. In addition, it exhibits a function as a doping material and has an appropriate steric hindrance to a π-conjugated polymer, so that a composite conductive polymer composition excellent in solubility in a specific solvent can be obtained. I found. In addition, the present inventors have found that the composite conductive polymer composition can be used for a dye-sensitized solar counter electrode, an antistatic film, and the like, and have completed the present invention.

　本発明で使用する高分子化合物（Ａ）の製造に当たっては、成分（ａ－１）と成分（ａ－２）のモル比が重要である。すなわち、本発明の高分子乳化剤は、芳香族基または脂環族基による疎水性とスルホン酸基による親水性を適宜バランスさせることにより、導電性高分子組成物に作用し、これを溶剤中に溶解可能とするためである。 In the production of the polymer compound (A) used in the present invention, the molar ratio of the component (a-1) to the component (a-2) is important. That is, the polymer emulsifier of the present invention acts on the conductive polymer composition by appropriately balancing the hydrophobicity due to the aromatic group or alicyclic group and the hydrophilicity due to the sulfonic acid group. This is to enable dissolution.

Examples of the polymerizable component include methyl (meth) acrylate, ethyl (meth) acrylate, butyl (meth) acrylate, 2-ethylhexyl (meth) acrylate, alkyl (meth) acrylate such as lauryl (meth) acrylate, (meth) Acrylic acid, 2-hydroxy (meth) acrylate, 3-hydroxypropyl (meth) acrylate, 2-hydroxybutyl (meth) acrylate, 4-hydroxybutyl (meth) acrylate, acetoacetoxyethyl (meth) acrylate, tetrahydrofurfuryl ( Examples thereof include meth) acrylate and N, N-dimethylaminoethyl (meth) acrylate, and the blending amount when blended is about 0 to 20 mol%.
　上記成分（ａ－１）、成分（ａ－２）および必要により加える重合性成分のラジカル重合反応は、公知の方法で行うことができる。例えば、これら各成分を混合した後、これに重合開始剤を添加し、加熱、光照射等により重合を開始することで製造することができる。 The radical polymerization reaction of the component (a-1), the component (a-2) and the polymerizable component added as necessary can be performed by a known method. For example, after mixing each of these components, a polymerization initiator can be added thereto and polymerization can be started by heating, light irradiation, or the like.
　上記高分子化合物（Ａ）を製造するために採用可能な重合法は、モノマー混合物から成分（ａ－１）が分離状態とならない状態で実施可能な方法であれば特に限定されず、例えば、溶液重合法、塊状（バルク）重合法、析出重合法等が採用される。 The polymerization method that can be employed for producing the polymer compound (A) is not particularly limited as long as it can be carried out in a state where the component (a-1) is not separated from the monomer mixture. A polymerization method, a bulk (bulk) polymerization method, a precipitation polymerization method, or the like is employed.
　また、重合反応に使用される重合開始剤は、上記各成分や、反応時に使用する溶媒に溶解可能なものであれば、特に限定されるものではない。この重合開始剤の例としては、過酸化ベンゾイル（ＢＰＯ）等の油溶性過酸化物系熱重合開始剤、アゾビスイソブチロニトリル（ＡＩＢＮ）等の油溶性アゾ系熱重合開始剤、アゾビスシアノ吉草酸（ＡＣＶＡ）等の水溶性アゾ系熱重合開始剤等が挙げられる。また、溶液重合の溶媒中の水割合が多い場合は、過硫酸アンモニウムや過硫酸カリウム等の水溶性過酸化物系熱重合開始剤、過酸化水素水等も使用することができる。さらに、フェロセンやアミン類等のレドックス剤の組み合わせも可能である。 Further, the polymerization initiator used in the polymerization reaction is not particularly limited as long as it can be dissolved in each of the above components and the solvent used during the reaction. Examples of this polymerization initiator include oil-soluble peroxide-based thermal polymerization initiators such as benzoyl peroxide (BPO), oil-soluble azo-based thermal polymerization initiators such as azobisisobutyronitrile (AIBN), azobiscyano Examples thereof include water-soluble azo-based thermal polymerization initiators such as herbal acid (ACVA). In addition, when the water ratio in the solvent for solution polymerization is large, water-soluble peroxide thermal polymerization initiators such as ammonium persulfate and potassium persulfate, hydrogen peroxide water, and the like can also be used. Furthermore, combinations of redox agents such as ferrocene and amines are possible.
　これらの重合開始剤の使用範囲は、上記化合物１モルに対し０.００１～０.１モルの範囲で任意に使用することができ、一括投入、滴下投入、逐次投入のいずれの方法も利用できる。また、塊状重合や少量（モノマーに対して５０ｗｔ％以下）の溶剤を使用した溶液重合の場合は、メルカプタンとメタロセンの組み合わせによる重合方法（特許文献９）も可能である。 These polymerization initiators can be used arbitrarily in the range of 0.001 to 0.1 mol with respect to 1 mol of the above compound, and any method of batch charging, dropping charging and sequential charging can be used. . Further, in the case of bulk polymerization or solution polymerization using a small amount of solvent (50 wt% or less based on the monomer), a polymerization method using a combination of mercaptan and metallocene (Patent Document 9) is also possible.
　更に、上記重合反応に用いる溶媒としては、メタノール、エタノール、イソプロピルアルコール、ブタノール等のアルコール系溶剤、アセトン、メチルエチルケトン、メチルイソブチルケトン等のケトン系溶剤、メチルセロソルブ、エチルセロソルブ、プロピレングリコールメチルエーテル、プロピレングリコールエチルエーテル等のグリコール系溶剤、乳酸メチル、乳酸エチル等の乳酸系溶剤等の溶媒を挙げることができる。 Furthermore, as the solvent used in the above polymerization reaction, alcohol solvents such as methanol, ethanol, isopropyl alcohol and butanol, ketone solvents such as acetone, methyl ethyl ketone and methyl isobutyl ketone, methyl cellosolve, ethyl cellosolve, propylene glycol methyl ether, propylene Examples of the solvent include glycol solvents such as glycol ethyl ether, and lactic acid solvents such as methyl lactate and ethyl lactate.
　更にまた、重合時には重合開始剤以外にも連鎖移動剤を併用しても良く、分子量を調整したい場合は、適宜使用可能である。使用できる連鎖移動剤としては、上記モノマーや溶剤に溶解する物であれば何れの化合物も使用可能であり、例えば、ドデシルメルカプタンやヘプチルメルカプタン等のアルキルチオール、メルカプトプロピオン酸（ＢＭＰＡ）の様な極性基を有する水溶性チオール、αスチレンダイマー（ＡＳＤ）等の油性ラジカル抑止剤等も適宜使用可能である。 Furthermore, a chain transfer agent may be used in addition to the polymerization initiator at the time of polymerization, and can be appropriately used when adjusting the molecular weight. As the chain transfer agent that can be used, any compound can be used as long as it is soluble in the above-mentioned monomers and solvents. For example, polar thiols such as alkylthiols such as dodecyl mercaptan and heptyl mercaptan, and mercaptopropionic acid (BMPA). A water-soluble thiol having a group, an oily radical inhibitor such as α-styrene dimer (ASD), and the like can be used as appropriate.
　また更に、この重合反応は、使用する溶剤（バルク重合の場合を除く）の沸点以下で行うのが好ましく、例えば、６５℃～８０℃程度が好ましい。但し、バルク重合やメルカプタンとメタロセンで行う特許文献９の様な重合を行う際は、２５℃～８０℃で行うことが好ましい。 Furthermore, this polymerization reaction is preferably carried out below the boiling point of the solvent used (except for bulk polymerization), for example, about 65 ° C. to 80 ° C. is preferable. However, when performing bulk polymerization or polymerization as in Patent Document 9 performed with mercaptan and metallocene, it is preferably performed at 25 ° C. to 80 ° C.
　かくして得られる重合物は、必要により精製し、高分子化合物（Ａ）とすることができる。この精製方法の例としては、ヘキサン等の油性貧溶媒を使用し、油性低分子不純物および残存モノマー、低分子不純物を取り除き、その後、アセトニトリル、メタノール、エタノール、アセトンなどの水性貧溶剤でポリマー析出等を行い、水系不純物、残存物を取り除く方法を挙げることができる。 The polymer thus obtained can be purified as necessary to obtain a polymer compound (A). As an example of this purification method, an oily poor solvent such as hexane is used to remove oily low molecular impurities and residual monomers and low molecular impurities, and then polymer precipitation with an aqueous poor solvent such as acetonitrile, methanol, ethanol, acetone, etc. And removing water-based impurities and residues.
　このように精製することが好ましい理由は、高分子化合物（Ａ）は、導電性高分子組成物中へドープ剤として導入され、スタック抑止剤、かつ溶剤可溶剤として作用するため、重合後の残存物としてそれ以外の重合開始剤残物、モノマー、オリゴマー、不均一組成物等が残存すると導電性高分子組成物の機能低下が問題となるので、これらを除去する必要が有るのである。そして、このように精製する結果、特許文献７の様な不均一なラジカル重合物が混在せず、均一な導電性高分子組成物の組成と高分子化合物（Ａ）の組成が一様に相溶化したような可溶状態を発現できるのである。 The reason why it is preferable to purify in this way is that the polymer compound (A) is introduced as a dopant into the conductive polymer composition and acts as a stack inhibitor and a solvent solubilizer. If other polymerization initiator residue, monomer, oligomer, heterogeneous composition, etc. remain as a product, the functional degradation of the conductive polymer composition becomes a problem, and it is necessary to remove these. As a result of such purification, the heterogeneous radical polymer as in Patent Document 7 is not mixed, and the composition of the uniform conductive polymer composition and the composition of the polymer compound (A) are uniformly matched. A solubilized state can be expressed.
　以上のようにして得られる高分子化合物（Ａ）は、そのＧＰＣ換算重量平均分子量が、３,０００～１００,０００であることが好ましい。重量平均分子量が３,０００に満たない場合は、高分子乳化剤としての機能が不十分である。逆に１０万以上になると、導電性ポリマー合成時の重合場（酸性水溶液）への溶解性が十分でない場合があり、また、高分子乳化剤自身の溶剤溶解性が悪くなり、導電性ポリマーの可溶化性に著しく悪い影響を与えることがある。 The polymer compound (A) obtained as described above preferably has a GPC equivalent weight average molecular weight of 3,000 to 100,000. When the weight average molecular weight is less than 3,000, the function as a polymer emulsifier is insufficient. On the other hand, if it exceeds 100,000, the solubility in the polymerization field (acidic aqueous solution) at the time of synthesis of the conductive polymer may not be sufficient, and the solvent solubility of the polymer emulsifier itself deteriorates. May significantly affect solubilization.

　本発明方法により複合導電性高分子組成物を製造する具体的方法の一例としては、まず、イオン交換水を、必要により酸性とした後、この中に、前記のようにして得た高分子化合物（Ａ）を添加した後、この中に原料である式（Ｉ）ないし（III）の化合物の１種または２種以上を加え、更に酸化剤を加えて酸化重合させる方法を挙げることができる。
　また、高分子化合物（Ａ）のイオン交換水への溶解性により、適宜アセトン、メチルエチルケトン等ケトン系溶剤、メタノール、エタノール、イソプロピルアルコール等アルコール系溶剤、アセトニトリル等の親水性の高い有機溶剤を併用しても良い。 As an example of a specific method for producing a composite conductive polymer composition by the method of the present invention, first, ion-exchanged water is acidified as necessary, and then the polymer compound obtained as described above is used. Examples thereof include a method in which one or more of the compounds of the formulas (I) to (III), which are raw materials, are added to this, and an oxidant is further added for oxidative polymerization after adding (A).
Depending on the solubility of the polymer compound (A) in ion-exchanged water, a ketone solvent such as acetone or methyl ethyl ketone, an alcohol solvent such as methanol, ethanol or isopropyl alcohol, or a highly hydrophilic organic solvent such as acetonitrile may be used in combination. May be.

The amount may be about 0.5 to 3.0 mol with respect to 1 mol of the compounds of formulas (I) to (III).
　また、反応に使用する酸化剤も複合導電性高分子組成物を形成する芳香族化合物（モノマー）のレドックスポテンシャルによって適宜調整が必要であるが、ペルオキソ二硫酸アンモニウム、ペルオキソ二硫酸カリウム、ペルオキソ二硫酸ナトリウム、塩化鉄（III）、硫酸鉄（III）、テトラフルオロホウ酸鉄（III）、ヘキサフルオロ燐酸鉄（III）、硫酸銅（II）、塩化銅（II）、テトラフルオロホウ酸銅（II）、ヘキサフルオロ燐酸銅（II）等が使用可能である。 In addition, the oxidizing agent used in the reaction also needs to be appropriately adjusted depending on the redox potential of the aromatic compound (monomer) forming the composite conductive polymer composition. However, ammonium peroxodisulfate, potassium peroxodisulfate, sodium peroxodisulfate , Iron (III) chloride, iron (III) sulfate, iron (III) tetrafluoroborate, iron (III) hexafluorophosphate, copper (II) sulfate, copper (II) chloride, copper (II) tetrafluoroborate In addition, copper (II) hexafluorophosphate can be used.
　また、反応における高分子化合物（Ａ）と化合物（Ｉ）ないし（III）との割合は、最終的に得られる複合導電性高分子組成物の性質にもよるため、単純に決定できるものではないが、たとえば、好ましい範囲の例は、高分子化合物（Ａ）中のスルホン酸基の数と、使用する化合物（Ｉ）～（III）のモル比により次のように示すことができる。 Further, the ratio of the polymer compound (A) to the compounds (I) to (III) in the reaction depends on the properties of the finally obtained composite conductive polymer composition, and therefore cannot be determined simply. However, for example, an example of a preferable range can be shown as follows by the number of sulfonic acid groups in the polymer compound (A) and the molar ratio of the compounds (I) to (III) used.
　すなわち、式（Ｉ）～（III）から選ばれる化合物１モルに対し、高分子化合物（Ａ）を、当該化合物中のスルホン酸基のモル比が０.２～１.５となる量で共存せしめればよい。 That is, the polymer compound (A) is present in an amount such that the molar ratio of the sulfonic acid groups in the compound is 0.2 to 1.5 with respect to 1 mol of the compound selected from the formulas (I) to (III).

The polymerization can be sufficiently carried out even with 1 mol or less per 1 mol of the monomer.
　更にまた、複合導電性高分子組成物を得るための重合反応の温度は、酸化反応後の発熱量や水素引き抜かれ易さが化合物（Ｉ）ないし（III）の種類により異なるため、好適な温度範囲が異なる。 Furthermore, since the temperature of the polymerization reaction for obtaining the composite conductive polymer composition varies depending on the types of the compounds (I) to (III), the calorific value after the oxidation reaction and the ease of extracting hydrogen vary depending on the types of the compounds (I) to (III). The range is different.
　一般的には、化合物（Ｉ）を利用する場合は、４０℃以下が好ましく、化合物（II）の場合は、９０℃以下、化合物（III）の場合は、２０℃以下とすることが好ましい。 Generally, when the compound (I) is used, the temperature is preferably 40 ° C. or lower, the compound (II) is preferably 90 ° C. or lower, and the compound (III) is preferably 20 ° C. or lower.
　また更に、複合導電性高分子組成物を高分子量化したい場合は、反応温度を相対的に低くし、反応時間を相対的に長めにすれば良く、低分子量化する場合は、この逆とすれば良い。 Furthermore, when it is desired to increase the molecular weight of the composite conductive polymer composition, the reaction temperature should be relatively low and the reaction time should be relatively long, and vice versa. It ’s fine.
　このようにして得られた重合物は、必要により更に洗浄等を行った後、目的物である複合導電性高分子組成物とすることができる。このものは、後記するように従来の導電性高分子組成物が溶解しなかったトルエン等の芳香族溶剤中で、安定に溶解するものである。 The polymer obtained in this manner can be made into a composite conductive polymer composition as a target product after further washing and the like as necessary.
