(ジアミン成分(A))
本発明に用いられるジアミン成分(A)を構成する必須成分である化学式(I)で表される含有フッ素芳香族ジアミン(a1)としては、2,2’-ビス(トリフルオロメチル)-ベンジジン、2,2’-ビス(トリフルオロメトキシ)-ベンジジン、2-トリフルオロメチル-ベンジジン、2-トリフルオロメトキシ-ベンジジン、2,2’-ビス(ペンタフルオロエチル)-ベンジジン、2,2’-ビス(ペンタフルオロエトキシ)-ベンジジン、2-ペンタフルオロエチル-ベンジジン、2-ペンタフルオロエトキシ-ベンジジン、2,2’-ビス(ヘプタフルオロプロパン)-ベンジジン、2,2’-ビス(ヘプタフルオロプロキシ)-ベンジジン、2-ヘプタフルオロプロパン-ベンジジン、2-ヘプタフルオロプロキシ-ベンジジン、2-ペンタフルオロエトキシ-ベンジジン、2,2’-ビス(ヘプタデカフルオロオクタン)-ベンジジン、2,2’-ビス(ヘプタデカフルオロオクタキシ)-ベンジジン、2-ヘプタデカフルオロオクタン-ベンジジン、2-ヘプタデカフルオロオクタキシ-ベンジジン、などが挙げられる。中でも2,2’-ビス(トリフルオロメチル)-ベンジジンが特に好ましい。これらは、単独で又は2種以上を組み合わせて用いられる。これらの含有フッ素芳香族ジアミン(a1)をジアミン成分(A)の5モル%以上、望ましくは10モル%以上、さらに望ましくは10モル%以上95モル%以下、含んでいることが好ましい。
に望ましくは50モル%以上95モル%以下含んでいることが好ましい。トランス-1,4-シクロヘキシルジアミン(a2)は未精製品のままだとポリイミドフィルムの色が濃色になるので、必要に応じてn-ヘキサン等によって再結晶、精製することが好ましい。トランス-1,4-シクロヘキシルジアミン(a2)は、酸二無水物との反応中に塩形成をおこしてしまい、分子量が上がり難いことが知られているが、必要に応じて、酢酸添加方法(例えば、「マクロモレキュール(Macromolecules),40巻,2007年,p.3527」に記載)や、N-シリル化法(例えば、「マクロモレキュール(Macromolecules)」,35巻,2002年,p.2277」に記載)の公知の方法により、合成することができる。

ポリイミド前駆体組成物が、前記溶媒成分を含むワニスである場合のポリイミド前駆体の濃度は、通常ポリイミド前駆体組成物の1~50重量%の範囲とされ、好ましくは3~35重量%の範囲、さらに好ましくは10~30重量%の範囲、とされる。濃度が1重量%未満である場合には、塗布後の膜厚が薄くなってしまい、フレキシブル基板として充分な膜厚が得られない傾向があり、50重量%を超える場合には、粘度が高くなってしまうため塗布特性が劣る場合がある。
本発明のポリイミド前駆体組成物は、ガラス基板、シリコンウエハや金属薄膜との密着性を向上させるために、シランカップリング剤、チタンカップリング剤等のカップリング剤を含有することができる。
本発明のポリイミド前駆体組成物は、加熱乾燥、脱水閉環してポリイミドを形成する。その加熱温度としては、通常100~400℃、好ましくは200~350℃、さらに好ましくは250~300℃の範囲を任意に選択することができる。
また、加熱時間は、通常、1分~6時間、好ましくは5分~2時間、さらに好ましくは15分~1時間とされる。
硬化雰囲気は、空気ガス、窒素ガス、酸素ガス、水素ガス、窒素/水素混合ガスが挙げられるが、硬化フィルムの表面の着色を抑えるためには、酸素濃度が少ない窒素ガス、窒素/水素混合ガスが好ましい。さらに好ましくは、酸素濃度が100ppm以下の窒素ガス、水素濃度が0.5%以下含む窒素/水素混合ガスが好ましい。

その後、3,3’,4,4’-ビフェニルテトラカルボン酸二無水物((b2)成分)29.421g(0.1モル)をゆっくりと加えた。室温で48時間撹拌してポリスチレン換算分子量Mw72400のポリイミド前駆体を含む粘度140ポイズのポリイミド前駆体組成物(ワニス)Iを得た。
このワニスIを用いて、実施例1と同様の方法及び同じ硬化条件でポリイミドフィルムを作成した。得られたポリイミドフィルムの膜厚10μm換算の400nm地点の光透過率、熱膨張係数、ガラス転移温度、屈折率差の結果は、まとめて(表1)に示す。
(実施例1) (a1)成分/(a2)成分=50/50
(b1)成分/(b2)成分=50/50
(実施例2) (a1)成分/(a2)成分=10/90
(b1)成分/(b2)成分=5/95
(実施例3) (a1)成分/(a2)成分=25/75
(b1)成分/(b2)成分=50/50
(実施例4) (a1)成分/(a2)成分=75/25
(b1)成分/(b2)成分=75/25
(比較例1) (a1)成分/(a2)成分=50/50
(b1)成分/(b2)成分=0/100
(比較例2) (a1)成分/(a2)成分=50/50
(b1)成分/(b2)成分=100/0
(比較例3) (a1)成分/(a2)成分=100/0
(b1)成分/(b2)成分=100/0
(比較例4) (a1)成分/(a2)成分=0/100
(b1)成分/(b2)成分=100/0
(比較例5) (a1)成分/(a2)成分=0/100
(b1)成分/(b2)成分=0/100
(比較例6) (a1)成分/(a2)成分=100/0
(b1)成分/(b2)成分=0/100
比較例と実施例との成分構成の相違は、実施例では、(a1)成分、(a2)成分、(b1)成分、及び(b2)成分の4成分から構成されているが、比較例では、前記4成分のいずれかが欠けている点にある。これら成分構成によるフィルム特性、すなわち400nm地点の光透過率、熱膨張係数、ガラス転移温度、屈折率差の違いは、上記(表1)に明らかである。すなわち、(a1)成分、(a2)成分、(b1)成分、及び(b2)成分の4成分の全部を必須成分として有することによって、各種電子装置に用いることができるフィルム特性を満足させるポリイミドフィルムを製造できるポリイミド前駆体組成物が得られることが、確認できる。
