Description
本発明は、ポリカーボネート樹脂の製造方法に関する。さらに詳しくは実質的に酸素不在下でホスゲン化反応及び重合反応を行うことにより、優れた色相のポリカーボネート樹脂を得ることを目的とするポリカーボネート樹脂の製造方法に関する。 The present invention relates to a method for producing a polycarbonate resin. More specifically, the present invention relates to a method for producing a polycarbonate resin which is intended to obtain a polycarbonate resin having an excellent hue by performing a phosgenation reaction and a polymerization reaction substantially in the absence of oxygen.
従来、ビスフェノールＡにカーボネート前駆物質を反応させて得られるポリカーボネート樹脂は透明性、耐熱性、機械的特性、寸法安定性が優れているがゆえにエンジニアリングプラスチックとして多くの分野に広く使用されているが、近年、加工成形品の軽薄短小化が進み、更なる耐熱性、剛性の向上したポリカーボネート樹脂が求められている。 Conventionally, polycarbonate resins obtained by reacting bisphenol A with a carbonate precursor have been widely used in many fields as engineering plastics because of their excellent transparency, heat resistance, mechanical properties, and dimensional stability. 2. Description of the Related Art In recent years, the light and thin size of processed molded articles has progressed, and a polycarbonate resin having further improved heat resistance and rigidity has been demanded.
ポリカーボネート樹脂の耐熱性、剛性を向上するためには、一般的に嵩高い動きにくい構造を有するビスフェノール類を用いる方法があり、種々のポリカーボネート樹脂が提案されている。中でも、特定のフルオレン構造を有するポリカーボネート樹脂が提案されている（例えば特許文献１，２参照）。しかしながら、これらの構造を有するポリカーボネート樹脂はホスゲン化反応及び重合反応中に著しく着色しやすく、したがって成形品の色相が黄色味を帯びるという問題があった。これを解決する手法として、ポリマー溶液に可視光を照射する方法（特許文献３参照）や、ポリマー溶液に金属不活性化剤及び／又は活性水素含有化合物を添加する方法（特許文献４参照）が提案されているが、これらは溶液色や流延法により作成するフィルムの色相を改善することはできても、熱履歴を与えるような成形法（射出成形法、圧縮成形法、溶融押出法など）にて成形体を作成した場合、上記改善法を用いても成形体の色相を改善することはできなかった。 In order to improve the heat resistance and rigidity of the polycarbonate resin, there is generally a method using bisphenols having a bulky structure that is difficult to move, and various polycarbonate resins have been proposed. Among them, a polycarbonate resin having a specific fluorene structure has been proposed (see, for example, Patent Documents 1 and 2). However, the polycarbonate resin having these structures is remarkably easily colored during the phosgenation reaction and the polymerization reaction, and thus there is a problem that the hue of the molded product is yellowish. Methods for solving this include a method of irradiating a polymer solution with visible light (see Patent Document 3) and a method of adding a metal deactivator and / or an active hydrogen-containing compound to the polymer solution (see Patent Document 4). Although proposed, these can improve the color of the film produced by solution color and casting method, but can be used to form a thermal history (injection molding method, compression molding method, melt extrusion method, etc.) ), The hue of the molded body could not be improved even using the above improvement method.
本発明の目的は、優れた耐熱性、剛性を持ち、且つ色相の良好なポリカーボネート樹脂の製造方法を提供することにある。色相が良好であることは、樹脂をレンズ、プリズム及び光ファイバーなどの光路変換部品、リフローハンダ付け部品、光ディスクなどの光学部材に用いる為には好ましい。また、樹脂に任意の色を付与するうえでも好ましい。 An object of the present invention is to provide a method for producing a polycarbonate resin having excellent heat resistance, rigidity and good hue. Good hue is preferable for using the resin for optical path conversion parts such as lenses, prisms and optical fibers, reflow soldering parts, and optical members such as optical disks. Moreover, it is preferable also when giving arbitrary colors to resin.
本発明者はこの目的を達成せんとして鋭意研究を重ねた結果、特定の二価フェノールを使用してポリカーボネート共重合体を製造する際、ホスゲン化反応及び重合反応を実質的に酸素不在下で行うことによって、上記目的を達成することを見出し、本発明に到達した。 As a result of intensive research aimed at achieving this object, the present inventor conducted a phosgenation reaction and a polymerization reaction substantially in the absence of oxygen when producing a polycarbonate copolymer using a specific dihydric phenol. As a result, the inventors have found that the above object can be achieved, and have reached the present invention.
すなわち、本発明によれば全芳香族ジヒドロキシ成分の５〜９５モル％が下記一般式［１］、 That is, according to the present invention, 5 to 95 mol% of the wholly aromatic dihydroxy component is represented by the following general formula [1],
で表されるジヒドロキシ成分からなるポリカーボネート樹脂の製造方法であって、ホスゲン化反応及び重合反応を実質的に酸素不在下で行うことを特徴とするポリカーボネート樹脂の製造方法が提供される。
A method for producing a polycarbonate resin comprising a dihydroxy component represented by the formula: wherein the phosgenation reaction and the polymerization reaction are carried out substantially in the absence of oxygen.
この製造法を用いることにより該ポリカーボネート樹脂５ｇを塩化メチレン５０ｍｌに遮光状態にて溶解した溶液のｂ値が５．０以下であるポリカーボネート共重合体の製造、提供が可能となる。なお、溶液のｂ値は４．０以下であることがより好ましく、３．５以下が最も好ましい。また、このポリカーボネート共重合体を用いて成形した場合色相の良好な成形品を得ることができる。この成形品のＹＩ値は厚さ２ｍｍの見本板で測定した場合、６．０以下であることが好ましい。なお、このＹＩ値は４．５以下がより好ましく、３．５以下が最も好ましい。ＹＩ値が６．０より大きい場合、色相が悪く、光学成形品として用いることが困難となる。 By using this production method, it is possible to produce and provide a polycarbonate copolymer having a b value of 5.0 or less in a solution obtained by dissolving 5 g of the polycarbonate resin in 50 ml of methylene chloride in a light-shielded state. The b value of the solution is more preferably 4.0 or less, and most preferably 3.5 or less. Moreover, when it shape | molds using this polycarbonate copolymer, a molded article with a favorable hue can be obtained. The YI value of this molded product is preferably 6.0 or less when measured with a sample plate having a thickness of 2 mm. The YI value is more preferably 4.5 or less, and most preferably 3.5 or less. When the YI value is larger than 6.0, the hue is bad and it is difficult to use as an optical molded product.
本発明のポリカーボネート共重合体の製造方法は、通常の芳香族ポリカーボネート樹脂を製造するそれ自体公知の反応手段、例えば芳香族ジヒドロキシ成分にホスゲンなどのカーボネート前駆物質を反応させる方法と同じであるが、ホスゲン化反応および重合反応において実質的に酸素を存在させない事が必要である。 The production method of the polycarbonate copolymer of the present invention is the same as a reaction means known per se for producing a normal aromatic polycarbonate resin, for example, a method of reacting an aromatic dihydroxy component with a carbonate precursor such as phosgene. It is necessary that substantially no oxygen is present in the phosgenation reaction and the polymerization reaction.
「実質的に酸素を存在させない」とは、系内の気相および液相に酸素を存在させないことを意味し、例えば気相および液相の酸素濃度が０．５ｐｐｍ以下、好ましくは０．２ｐｐｍ以下、更に好ましくは０．１ｐｐｍ以下であることを意味する。 “Substantially no oxygen” means that no oxygen is present in the gas phase and liquid phase in the system. For example, the oxygen concentration in the gas phase and liquid phase is 0.5 ppm or less, preferably 0.2 ppm. Hereinafter, it means more preferably 0.1 ppm or less.
以下に本発明の目的である、優れた耐熱性、剛性を持ち、且つ色相の良好なポリカーボネート樹脂の製造方法について基本的な手段を簡単に説明する。 The basic means of the method for producing a polycarbonate resin having excellent heat resistance, rigidity and good hue, which is the object of the present invention, will be briefly described below.
カーボネート前駆物質として、例えばホスゲンを使用する反応では、通常酸結合剤および溶媒の存在下に反応を行う。酸結合剤としては、例えば水酸化ナトリウム、水酸化カリウムなどのアルカリ金属水酸化物またはピリジンなどのアミン化合物が用いられる。溶媒としては、例えば塩化メチレン、クロロベンゼンなどのハロゲン化炭化水素が用いられる。この時、これらの溶媒は、使用する前に窒素等を吹き込む手法及び還元剤を添加する手法又はその両方の手法で溶媒中の酸素を除いておくことことにより色相の良好なポリカーボネート樹脂の製造が可能となる。また反応促進のために例えば第三級アミンまたは第四級アンモニウム塩などの触媒を用いることもできる。その際、反応温度は通常０〜４０℃であり、反応時間は数分〜５時間である。反応の際にも、窒素を吹き込む手法やハイドロサルファイトのような還元剤を添加することで反応溶液中の酸素を常に除いておくことにより、さらに色相の良好なポリカーボネート樹脂の製造が可能となる。また、反応槽に窒素シール等を施し、酸素の侵入を防止する事も重要である。さらにその後の精製工程も窒素雰囲気下において実施することも色相改善には効果がある。 In a reaction using, for example, phosgene as a carbonate precursor, the reaction is usually performed in the presence of an acid binder and a solvent. As the acid binder, for example, an alkali metal hydroxide such as sodium hydroxide or potassium hydroxide or an amine compound such as pyridine is used. As the solvent, for example, halogenated hydrocarbons such as methylene chloride and chlorobenzene are used. At this time, these solvents can be used to produce a polycarbonate resin having a good hue by removing oxygen in the solvent by blowing nitrogen or the like and / or adding a reducing agent before use. It becomes possible. In order to accelerate the reaction, a catalyst such as a tertiary amine or a quaternary ammonium salt can also be used. In that case, reaction temperature is 0-40 degreeC normally, and reaction time is several minutes-5 hours. Even during the reaction, it is possible to produce a polycarbonate resin with a better hue by always removing oxygen in the reaction solution by adding a reducing agent such as a method of blowing nitrogen or hydrosulfite. . It is also important to prevent the invasion of oxygen by applying a nitrogen seal or the like to the reaction tank. Furthermore, the subsequent purification step is also effective in improving the hue by performing it in a nitrogen atmosphere.
本発明の芳香族ポリカーボネート共重合体は、それを構成する芳香族ジヒドロキシ成分として、９，９−ビス（４−ヒドロキシ−３−メチルフェニル）フルオレンが全芳香族ジヒドロキシ成分の５〜９５モル％、好ましくは１０〜９５モル％、さらに好ましくは３０〜８５モル％である。５モル％未満の場合、９，９−ビス（４−ヒドロキシ−３−メチルフェニル）フルオレン成分を用いる目的の一つである耐熱用材料としての特性が不満足なものとなり好ましくない。 The aromatic polycarbonate copolymer of the present invention has 9,9-bis (4-hydroxy-3-methylphenyl) fluorene as an aromatic dihydroxy component constituting it, 5 to 95 mol% of the total aromatic dihydroxy component, Preferably it is 10-95 mol%, More preferably, it is 30-85 mol%. If it is less than 5 mol%, the properties as a heat-resistant material, which is one of the purposes of using the 9,9-bis (4-hydroxy-3-methylphenyl) fluorene component, are unsatisfactory.
前記９，９−ビス（４−ヒドロキシ−３−メチルフェニル）フルオレンは、その１０ｇをエタノール５０ｍｌに溶解した溶液を光路長３０ｍｍで測定したｂ値が好ましくは６．０以下、より好ましくは５．５以下であり、さらに好ましくは５．０以下である。ｂ値が上記範囲内であれば、得られるポリカーボネート共重合体から形成される成形体は色相および強度が高く、延伸フィルム特性も良好となり好ましい。 The 9,9-bis (4-hydroxy-3-methylphenyl) fluorene has a b value of preferably 6.0 or less, more preferably 5. measured by measuring a solution of 10 g in 50 ml of ethanol at an optical path length of 30 mm. 5 or less, more preferably 5.0 or less. When the b value is within the above range, a molded product formed from the obtained polycarbonate copolymer has a high hue and strength, and a stretched film property is also preferable.
通常、この９，９−ビス（４−ヒドロキシ−３−メチルフェニル）フルオレンはｏ−クレゾールとフルオレノンの反応によって得られる。前記特定のｂ値を有する９，９−ビス（４−ヒドロキシ−３−メチルフェニル）フルオレンは、特定の処理を行い不純物を除去することによって得ることができる。具体的には、ｏ−クレゾールとフルオレノンの反応後に、未反応のｏ−クレゾールを留去した後、残さをアルコール系、ケトン系またはベンゼン誘導体系の溶媒に溶解し、これに活性白土または活性炭を加えてろ過後、ろ液から結晶化した生成物をろ過して精製された９，９−ビス（４−ヒドロキシ−３−メチルフェニル）フルオレンを得ることができる。除去される不純物としては、２，４′−ジヒドロキシ体、２，２′−ジヒドロキシ体および構造不明の不純物等である。かかる精製に用いるアルコール系の溶媒としてはメタノール、エタノール、プロパノール、ブタノール等の低級アルコール、ケトン系の溶媒としてはアセトン、メチルエチルケトン、メチルイソプロピルケトン、シクロヘキサノン等の低級脂肪族ケトン類およびこれらの混合物が好ましく、ベンゼン誘導体系の溶媒としてはトルエン、キシレン、ベンゼンおよびこれらの混合物が好ましい。溶媒の使用量はフルオレン化合物が十分に溶解する量であれば足り、通常フルオレン化合物に対して２〜１０倍量程度である。活性白土としては市販されている粉末状または粒状のシリカ−アルミナを主成分とするものが用いられる。また、活性炭としては市販されている粉末状または粒状のものが用いられる。 The 9,9-bis (4-hydroxy-3-methylphenyl) fluorene is usually obtained by the reaction of o-cresol and fluorenone. The 9,9-bis (4-hydroxy-3-methylphenyl) fluorene having the specific b value can be obtained by performing a specific treatment to remove impurities. Specifically, after the reaction between o-cresol and fluorenone, unreacted o-cresol is distilled off, and the residue is dissolved in an alcohol, ketone, or benzene derivative solvent, and activated clay or activated carbon is added thereto. In addition, after filtration, 9,9-bis (4-hydroxy-3-methylphenyl) fluorene purified by filtering the product crystallized from the filtrate can be obtained. Examples of impurities to be removed include 2,4′-dihydroxy form, 2,2′-dihydroxy form and impurities whose structure is unknown. The alcohol solvent used for such purification is preferably a lower alcohol such as methanol, ethanol, propanol or butanol, and the ketone solvent is preferably a lower aliphatic ketone such as acetone, methyl ethyl ketone, methyl isopropyl ketone or cyclohexanone and a mixture thereof. As the benzene derivative solvent, toluene, xylene, benzene and a mixture thereof are preferable. The amount of the solvent used is sufficient if the fluorene compound is sufficiently dissolved, and is usually about 2 to 10 times the amount of the fluorene compound. As the activated clay, a commercially available powdery or granular silica-alumina main component is used. Further, as the activated carbon, commercially available powdery or granular materials are used.
本発明の芳香族ポリカーボネート共重合体において用いられる上記一般式[２]で示される他のジヒドロキシ成分としては、通常芳香族ポリカーボネートのジヒドロキシ成分として使用されているものであればよく、例えばハイドロキノン、レゾルシノール、４，４′−ビフェノール、１，１−ビス（４−ヒドロキシフェニル）エタン（ビスフェノールＥ）、２，２−ビス（４−ヒドロキシフェニル）プロパン（ビスフェノールＡ）、２，２−ビス（４−ヒドロキシ−３−メチルフェニル）プロパン（ビスフェノールＣ）、２，２−ビス（４−ヒドロキシフェニル）ブタン、１，１−ビス（４−ヒドロキシフェニル）−１−フェニルエタン、１，１−ビス（４−ヒドロキシフェニル）シクロヘキサン（ビスフェノールＺ）、１，１−ビス（４−ヒドロキシフェニル）−３，３，５−トリメチルシクロヘキサン、２，２−ビス（４−ヒドロキシフェニル）ペンタン、４，４′−（ｐ−フェニレンジイソプロピリデン）ジフェノール、α，α′−ビス（４−ヒドロキシフェニル）−ｍ−ジイソプロピルベンゼン（ビスフェノールＭ）、１，１−ビス（４−ヒドロキシフェニル）−４−イソプロピルシクロヘキサンなどが挙げられ、なかでもビスフェノールＡ、ビスフェノールＺ、ビスフェノールＣ、ビスフェノールＥ、ビスフェノールＭが好ましく、特にビスフェノールＡが好ましい。 The other dihydroxy component represented by the above general formula [2] used in the aromatic polycarbonate copolymer of the present invention may be any one that is usually used as a dihydroxy component of an aromatic polycarbonate.
