ポリイミド前駆体溶液の粘度は、ブルックフィールド回転粘度計(Brookfield rotational viscometer)で25℃で測定した。

下記表3に記載のテトラカルボン酸二無水物及びジアミンを使用したことを除いては、実施例11と同じ方法でポリイミド前駆体溶液を製造し、前記ポリイミド前駆体溶液の粘度及びポリアミド酸の分子量を表3に示した。

図1と図2は、比較例1と実施例1とのフィルム断面をFIBによって処理してSEMで観察した結果である。ポリイミド前駆体溶液の粘度が相対的に高くて、脱泡効果が低下した比較例1のフィルム断面には、マイクロサイズのポアが存在する一方、実施例1のフィルム断面には、ポアがないことが分かる。
実施例1、実施例2、実施例5、実施例9及び実施例10から製造されたポリイミド前駆体溶液をガラス基板にスピンコーティングした。ポリイミド前駆体溶液が塗布されたガラス基板をオーブンに入れ、2℃/minの速度で加熱し、80℃で15分、150℃で30分、220℃で30分、380℃で1時間を保持して硬化工程を進行した。硬化工程完了後に、ガラス基板を水に浸してガラス基板上に形成されたフィルムを取り外した後、オーブンで100℃に乾燥して、ポリイミドフィルムを製造した。
フィルムを5x20mmのサイズに切って、試料を準備した後、アクセサリーを用いて試料をローディングする。実際に測定されるフィルムの長さは、16mmに同様にした。フィルムを引っ張る力を0.02Nに設定し、100〜400℃の温度範囲で5℃/minの昇温速度で1次昇温工程を進行した後、400〜100℃の温度範囲で4℃/min の冷却速度で冷却(cooling)される時の熱膨張変化態様をTMA(TA社のQ400)で測定した。
熱分解温度は、ISO 11359の方法で測定した。

透過度は、JIS K 7105に基づいて透過率計(モデル名HR−100、Murakami Color Research Laboratory製造)で測定した。
