等が挙げられる。
反応に際して、N-フェニルイサチン化合物に対するフェニルフェノール化合物の仕込みモル比は、理論値(2.0)以上であれば、特に限定されるものではないが、通常、2.5倍モル量以上、好ましくは、2.5~20倍モル量の範囲、特に好ましくは3~10倍モル量の範囲で用いられる。酸触媒としては、例えば、塩酸、塩化水素ガス、60~98%硫酸、85%リン酸等の無機酸、p-トルエンスルホン酸、メタンスルホン酸、シュウ酸、蟻酸、トリクロロ酢酸又はトリフルオロ酢酸等の有機酸、ヘテロポリ酸等の固体酸等を挙げることができる。好ましくは 塩化水素ガスである。このような酸触媒の使用量は反応条件によって好適な量は異なるが、例えば塩化水素ガスの場合は、反応系の空気を窒素ガス等の不活性ガスで置換した後、塩化水素ガスを吹き込み、反応容器内の気相中の塩化水素ガス濃度を75~100容量%とし、反応液中の塩化水素濃度を飽和濃度にするのがよい。35%塩酸の場合はフェニルフェノール化合物100重量部に対して、5~70重量部の範囲、好ましくは、10~40重量部の範囲、より好ましくは20~30重量部の範囲で用いられる。
反応に際し、酸触媒と共に必要に応じて助触媒を用いてもよい。例えば、塩化水素ガスを触媒として用いる場合、助触媒としてチオール類を用いることによって、反応速度を加速させることができる。このようなチオール類としては、アルキルメルカプタン類やメルカプトカルボン酸類が挙げられ、好ましくは、炭素数1~12のアルキルメルカプタン類や炭素数1~12のメルカプトカルボン酸であり、例えば、メチルメルカプタン、エチルメルカプタン、n-オクチルメルカプタン、n-ラウリルメルカプタン等やそれらのナトリウム塩等のようなアルカリ金属塩、チオ酢酸、β-メルカプトプロピオン酸等が挙げられる。また、これらは単独又は二種類以上の組み合わせで使用できる。
助触媒としてのチオール類の使用量は、原料のN-フェニルイサチン化合物に対し通常1~30モル%の範囲、好ましくは2~10モル%の範囲で用いられる。
また、フェニルフェノール化合物の凝固点を下げ酸触媒の反応を促進するため、必要に応じて少量の水を添加してもよい。特に酸触媒が塩化水素ガスの場合は、水は触媒の塩化水素ガスの吸収を促進する理由で好ましい。水を添加する場合その添加量は、フェニルフェノール化合物100重量部に対し、0.5~5.0重量部の範囲が好ましい。
反応温度は、通常10~60℃、好ましくは25~50℃の範囲である。反応圧力は、通常、常圧下で行われるが、用いてもよい有機溶媒の沸点によっては、反応温度が前記範囲内になるように、加圧又は減圧下で行ってもよい。このような条件下で反応を行えば、反応は、通常1~30時間程度で終了する。
反応の終点は、液体クロマトグラフィー又はガスクロマトグラフィー分析にて確認することができる。未反応のN-フェニルイサチン化合物が消失し、目的物の増加が認められなくなった時点を反応の終点とするのが好ましい。
フェニルフェノール化合物に対する反応収率は、通常75~95モル%程度である。
反応終了後、得られた反応混合物に、アンモニア水、水酸化ナトリウム水溶液等のアルカリ溶液を加えて酸触媒を中和して、本発明に係る一般式(1)で表されるビスフェノールを含む反応終了混合液を得る。
該反応終了混合物から目的物を分離精製する方法は公知の方法を用いることができる。例えば、中和した反応終了混合液をそのまま又は一旦加熱して均一の溶液とした後、冷却するか、もしくはメタノール等の晶析溶媒を加えた後、冷却して、結晶を析出させ、析出結晶をろ別することで、粗製又は高純度の目的物を得ることができる。
このようにして得られた目的とするビスフェノールは、必要に応じて、さらに精製して高純度品としてもよい。特にポリカーボネートの原料ジヒドロキシフェノールとして用いる場合は高純度品とするのが好ましい。例えば、上記得られた目的物の結晶を、再度、適宜の溶媒、例えばトルエン等の芳香族溶媒、メチルエチルケトン等の脂肪族ケトン溶媒等の溶媒に溶解し、その後メタノール、水等の晶析溶媒を加えて再度冷却、晶析し、ろ別、乾燥する。または、上記晶析操作の代わりに反応終了後、反応終了混合物から反応溶媒等を減圧下に濃縮し、その残渣をカラムクロマトグラフィー等により精製することで目的物の高純度品を得ることもできる。
本発明の芳香族ポリカーボネートは、下記一般式(2)で表される繰り返し単位を含む芳香族ポリカーボネートである。
従って、上記一般式(2)で表される繰り返し単位を含む芳香族ポリカーボネートにおいて好ましい繰り返し単位を含む芳香族ポリカーボネートは下記一般式(7)で表される。
共重合原料を用いる場合、全ジヒドロキシ化合物中、主として用いられる上記一般式(1)で表されるビスフェノール化合物以外のジヒドロキシ化合物共重合原料の割合は、本発明の芳香族ポリカーボネートの効果を妨げない限り特に制限はないが、好ましくは0~20モル%の範囲、より好ましくは0~10モル%の範囲、さらに好ましくは0~5モル%の範囲、特に好ましくは0~2モル%の範囲である。
本発明の上記一般式(2)で表される繰り返し単位を含む芳香族ポリカーボネートを溶融重縮合で製造する溶融エステル交換法についてさらに詳しく説明する。ここで、溶融エステル交換法としては従来公知の方法を用いることができる。
例えば、原料芳香族ジヒドロキシ化合物が3,3-ビス(4-ヒドロキシ-3-フェニルフェニル)-1-フェニル-1H-インドール-2-オンであり、原料炭酸ジエステルがジフェニルカーボネートである場合の、本発明に係る芳香族ポリカーボネートを得る反応を下記に反応式で示す。
芳香族ジヒドロキシ化合物と反応させる炭酸ジエステルとしては、具体的には、例えば、ジフェニルカーボネート,ジトリルカーボネート,ビス(m-クレジル)カーボネート等の炭酸ジアリール、ジメチルカーボネート,ジエチルカーボネート,ジシクロヘキシルカーボネート等の炭酸ジアルキル、メチルフェニルカーボネート,エチルフェニルカーボネート,シクロヘキシルフェニルカーボネート等の炭酸アルキルアリール又はジビニルカーボネート、ジイソプロペニルカーボネート、ジプロペニルカーボネート等の炭酸ジアルケニル等が挙げられる。好ましくは炭酸ジアリールであり、特に好ましいのはジフェニルカーボネートである。
本発明に係る芳香族ポリカーボネートを得る芳香族ジヒドロキシ化合物と炭酸ジエステルとの混合比率は、芳香族ジヒドロキシ化合物1モルに対して、炭酸ジエステルを通常0.5~1.5モル倍、好ましくは0.6~1.2モル倍を用いる。
中でも、アルカリ金属化合物が好ましく、特に炭酸セシウム、水酸化セシウム等のセシウム化合物が好ましい。
触媒の使用量は、触媒残留物が生成ポリカーボネートの品質上の問題が生じない範囲で用いられ、触媒の種類により好適な添加量が異なるので一概には言えないが概略、例えばビスフェノール化合物1モルに対して通常0.05~100μモル、好ましくは0.08~50μモル、より好ましくは0.1~20μモル、さらに好ましくは0.1~5μモルである。触媒はそのままで添加してもよいし、溶媒に溶解して添加してもよく、溶媒としては例えば、水、フェノール等の反応に影響しないものが好ましい。
溶融エステル交換反応の反応条件は、温度は通常120~360℃の範囲、好ましくは150~280℃の範囲、より好ましくは180~260℃の範囲である。反応温度が低すぎるとエステル交換反応が進行せず、反応温度が高いと分解反応等の副反応が進行するので好ましくない。反応は好ましくは減圧下で行われ、反応圧力は反応温度において原料である炭酸ジエステルが系外に留出せず副生するフェノールが留出する圧力であることが好ましい。このような反応条件において、反応は通常0.5~10時間程度で完結する。
上記反応工程により得られた芳香族ポリカーボネートを含む反応終了物は、通常、反応温度近傍では溶融状態にある透明な粘稠物であり、常温近傍では固形体である。
必要に応じて行われてもよい低分子量成分の分離低減処理は、例えば特開平7-192310公報記載のように、芳香族ポリカーボネートを適宜の良溶媒に溶解し、その後メタノール等の貧溶媒中で芳香族ポリカーボネートを沈殿し、乾燥することにより、低分子量成分が低減された粒子状、粉状、フレーク状等の本発明に係る芳香族ポリカーボネートを得ることができる。
第二工程においては、第一工程で得られた芳香族ポリカーボネートオリゴマーに、減圧下のもとで必要に応じて4級ホスホニウム塩等、適宜前述のエステル交換触媒を追加添加し、不活性ガスを導入して、撹拌下に、芳香族ポリカーボネートのガラス転移温度以上で、且つ固相重合中の結晶化オリゴマーが溶融しない固相状態又は膨潤固相状態で残余のフェノールを留出させつつ、反応させることにより高分子量芳香族ポリカーボネートを得る。
第一工程の反応と第二工程の反応は、別々に行っても、また、連続して行っても良い。ここで、芳香族ポリカーボネートオリゴマーとは通常、例えば重量平均分子量が500~15000程度である。また、高分子量芳香族ポリカーボネートとは通常、例えば重量平均分子量が15000~100000程度である。しかし、本発明の芳香族ポリカーボネートはこのような分子量には限定されない。
例えば、本発明のビスフェノール化合物とエピクロロヒドリンを反応させることにより、3,3-ビス(4-グリシジルオキシ-3-フェニルフェニル)-1-フェニル-1H-インドール-2-オン等が得られ、これらを原料にエポキシ樹脂を得ることができる。
本発明のビスフェノール化合物と2-(3-オキセタニル)ブチルトシレートを反応させることにより、3,3-ビス(4-[2-(3-オキセタニル)]ブトキシ-3-フェニルフェニル)-1-フェニル-1H-インドール-2-オン等が得られ、これらを原料にオキセタン樹脂を得ることができる。
本発明のビスフェノール化合物とアクリル酸(又はメタクリル酸)を反応させることで3,3-ビス(4-(メタ)アクリロキシ-3-フェニルフェニル)-1-フェニル-1H-インドール-2-オン等を得ることができ、これらを原料に樹脂とすることができる。
本発明のビスフェノール化合物とホルムアルデヒドを反応させることにより3,3-ビス(5-ヒドロキシメチル-4-ヒドロキシ-3-フェニルフェニル)-1-フェニル-1H-インドール-2-オン等を得ることができる。またこのメチロール化合物をメタノールと反応させることで3,3-ビス(5-メトキシメチル-4-ヒドロキシ-3-フェニルフェニル)-1-フェニル-1H-インドール-2-オン等を得ることができる。
本発明のビスフェノール化合物と1,2-ナフトキノンジアジド-5-スルホン酸クロリドを反応させることにより、3,3-ビス(4-[(6-ジアゾ-5-オキソナフチル)スルホニルオキシ]-3-フェニルフェニル)-1-フェニル-1H-インドール-2-オン等が得られ、これらは感光性組成物に用いることができる。
その他用途として本発明化合物は、フェノール性水酸基を複数有しているので、ポリカーボネート以外にも、ポリエステル、ポリアリレート、ポリエーテルエーテルケトン、ポリサルフォン、ノボラック、レゾール等の樹脂原料、その他i線レジスト添加剤、顕色剤、酸化防止剤としての利用も期待できる。
また、本発明のビスフェノール化合物原料として得られる本発明の芳香族ポリカーボネートは、高分子量ポリカーボネートとすることで、透明性、耐熱性、機械特性、耐衝撃性、流動性等に優れ、光ディスク、スマートフォン等に用いられる光学レンズ、フラットパネルディスプレイ等に用いられる光学フィルムなどの光学用途や、エンジニアリングプラスチックとして自動車分野、電気・電子分野、各種容器等、様々な分野での使用が期待できる。
また、芳香族ポリカーボネートオリゴマーとしては、各種重合方法により、高分子量ポリカーボネートを製造する際の原料として使用することができるだけでなく、表面改質剤、難燃剤、紫外線吸収剤、流動性改質剤、可塑剤、樹脂アロイ用溶化剤などのポリマー改質剤等、添加剤としても幅広く利用することができる。
