DSC分析は、TAインスツルメント社のQ20システムを使用して行った。測定は、温度を35℃から400℃まで10℃/分の昇温速度で昇温しつつ、N2フロー雰囲気で行い、硬化前と硬化後に試験片の発熱量を測定し、これにより、下記数式によって硬化度を測定した。
硬化度=1−(硬化後の試験片の発熱量/硬化前の試料の発熱量)
TGA分析は、Mettler−Toledo社のTGA e850装備を使用して行った。測定は、実施例または比較例の組成物について25℃から900℃まで10℃/分の昇温速度で昇温しつつ、N2フロー雰囲気で分析した。
化学式Aで表示される化合物をアルミニウムティシュィを利用して240℃のホットプレート上で10分間溶融させた。完全に溶融した前記化合物に硬化剤(1,3−Bis(3−aminophenoxy)benzene)を前記化合物1モル当たり約0.15モルの割合で添加し、さらに、240℃のホットプレートで10分間均一に混合させ、冷却して、プレポリマー形態の重合性組成物を製造した。
硬化条件を下記表1に示されたように調節したことを除いて、実施例1と同一に硬化を進めた。
硬化条件を下記表1に示されたように調節したことを除いて、実施例1と同一に硬化を進めた。
