以下、実施例を挙げて本発明を具体的に説明するが、本発明はこれらにより何ら制限されるものではない。なお、実施例中の相対粘度、融点、結晶化温度、酸化熱量、及び飽和吸水率の測定、耐薬品性、耐加水分解性の評価、フィルム成形及び引張強度、曲げ弾性率、耐衝撃強度、熱変形温度の測定、エタノール透過性は以下の方法により行った。
ηrはポリアミドの96%硫酸溶液(濃度:1.0g/dl)を使用してオストワルド型粘度計を用いて25℃で測定した。
Tm及びTcは、PerkinELmer社製PYRIS Diamond DSC用いて窒素雰囲気下で測定した。30℃から280℃まで20℃/分の速度で昇温し(昇温ファーストランと呼ぶ)、280℃で5分保持したのち、30℃まで20℃/分の速度で降温し(降温ファーストランと呼ぶ)、次に280℃まで20℃/分の速度で昇温した(昇温セカンドランと呼ぶ)。得られたDSCチャートから降温ファーストランの発熱ピーク温度をTc、昇温セカンドランの吸熱ピーク温度をTmとした。

(3)のフィルム成形で得られたフィルムに対し、セイコーインスツルメンツ社製 RDC220を用いて耐酸化性の評価を行った。セイコーインスツルメンツ社製 RDC220に得られたフィルムをセットし、100ml/分の窒素気流下で、昇温速度20℃/分で、室温から190℃まで昇温し、190℃で保持し、開始から60分後に、100ml/分の酸素気流下に切り替え、フィルムの発熱量を測定した。測定された発熱量を酸化熱量とし、耐酸化性の指標として用いた。
ポリオキサミド樹脂を(6)の条件で成形したフィルム(寸法:20mm×10mm、厚さ0.25mm;重量約0.05g)を23℃のイオン交換水に浸漬し、所定時間ごとにフィルムを取り出し、フィルムの重量を測定した。フィルム重量の増加率が0.2%の範囲で3回続いた場合にポリアミド樹脂フィルムへの水分の吸収が飽和に達したと判断して、水に浸漬する前のフィルムの重量(Xg)と飽和に達した時のフィルムの重量(Yg)から式(1)により飽和吸水率(%)を算出した。
得られるポリオキサミドの熱プレスフィルムを以下に列挙する薬品中に7日間浸漬した後に、フィルムの重量残存率(%)及び外観の変化を観測した。濃塩酸、64%硫酸、30%水酸化ナトリウム水溶液、5%過マンガン酸カリウム水溶液のそれぞれの溶液においては23℃下で、また、ベンジルアルコールについては50℃において浸漬した試料について試験を行った。

エタノール透過係数(g・mm/m2・day・atom)=[透過重量(g)×フィルム厚さ(mm)]/[透過面積(m2)×日数(day)×圧力(atom)]
