Description
攪拌装置を備えた反応容器中に、2, 2−ビス(3−アミノ−4−ヒドロキシフェニル)ヘキサフルオロプロパン3.41g、トリス(3−アミノプロピル)アミン135.5mgを配合し、これらを、乾燥N,N−ジメチルアセトアミド20.2mlに溶解させた。この溶液に、4, 4′−(ヘキサフルオロイソプロピリデン)ジフタル酸無水物4.60gを攪拌しながらゆっくり加え、40℃で5時間攪拌することにより、ポリイミド前駆体であるポリアミド酸のN,N−ジメチルアセトアミド溶液を得た(固形分濃度:30%、溶液総量:27.0g、三官能アミン配合比率:7mol%)。
上記のようにして得られたポリアミド酸溶液を、スピンコート法によってガラス基板に塗布し、90℃に加熱したホットプレートを用い、15分間プレベークした後、さらに減圧条件下で、300℃で2時間加熱を行い、上記ガラス基板から上記ポリアミド酸のイミド化物を剥がし、これによりフィルム(ポリイミドフィルム)を作製した(成膜後の厚み:4.8μm)。
また、このようにして得られたポリアミド酸溶液を用いて、実施例1に記載の手法に従い、ポリイミドフィルムを作製した(成膜後の厚み:5.6μm)。
また、このようにして得られたポリアミド酸溶液を用いて、実施例1に記載の手法に従い、ポリイミドフィルムを作製した(成膜後の厚み:5.0μm)。
攪拌装置を備えた反応容器中に、2, 2−ビス(3−アミノ−4−ヒドロキシフェニル)ヘキサフルオロプロパン3.30g、トリス(3−アミノプロピル)アミン188.3mgを配合し、これらを、乾燥N,N−ジメチルアセトアミド20.2mlに溶解させた。この溶液に、4, 4′−(ヘキサフルオロイソプロピリデン)ジフタル酸無水物4.67gを攪拌しながらゆっくり加え、40℃で攪拌したところ、ポリアミド酸は直ちにゲル化した。
そのため、実施例1に記載の手法に従いポリイミドフィルムを作製することができなかったが、物理的に圧延し、300℃で2時間加熱を行うことにより、フィルムを作製することができた(上記ポリアミド酸の三官能アミン配合比率:10mol%)。
攪拌装置を備えた反応容器中に、2, 2−ビス(3−アミノ−4−ヒドロキシフェニル)ヘキサフルオロプロパン4.12gを、乾燥N,N−ジメチルアセトアミド22.6mlに溶解させた。この溶液に、4, 4′−(ヘキサフルオロイソプロピリデン)ジフタル酸無水物4.51gを攪拌しながらゆっくり加え、40℃で5時間攪拌することにより、ポリイミド前駆体であるポリアミド酸のN,N−ジメチルアセトアミド溶液を得た(固形分濃度30%、30.2g、三官能アミン配合比率:0mol%)。
また、このようにして得られたポリアミド酸溶液を用いて、実施例1に記載の手法に従い、ポリイミドフィルムを作製した(成膜後の厚み:5.5μm)。
攪拌装置を備えた反応容器中に、2, 2−ビス(3−アミノフェニル)ヘキサフルオロプロパン3.76gを、乾燥N,N−ジメチルアセトアミド22.6mlに溶解させた。この溶液に、4, 4′−(ヘキサフルオロイソプロピリデン)ジフタル酸無水物5.00gを攪拌しながらゆっくり加え、40℃で5時間攪拌することにより、ポリイミド前駆体であるポリアミド酸のN,N−ジメチルアセトアミド溶液を得た(固形分濃度:30%、溶液総量:26.5g、三官能アミン配合比率:0mol%)。
また、このようにして得られたポリアミド酸溶液を用いて、実施例1に記載の手法に従い、ポリイミドフィルムを作製した。
熱機械分析装置(TMA)により耐リフロー性試験(270℃以上での耐分解性試験)を行い、3%以上の重量減少を起こさなかったものを○と評価した。
7cm×7cm×厚み0.025mmの平滑なSUS基材(SUS 304H−TA、新日本製鐵社製)の片面に、ポリアミド酸溶液を塗工し、80℃で10分間加熱し、ついで150℃で30分間加熱した後、さらに350℃で2時間加熱することにより、厚み約20μmのポリイミド層を上記SUS基材上に形成してなるサンプルを作製した。このようにして得られたサンプルの反り(カール)を、次のようにして測定・評価した。すなわち、図1に示すように、サンプル1を平らな場所におき、そのエッジ部分の高さTを測定し、Tが0.5cm以下であるものを、本発明の基準を満たすものとして評価した。
