ポリマーとしては、ジアミン化合物をモノマーとして使用するものであれば、特に制限はなく、ポリイミド、ポリベンゾオキサゾール、これらの前駆体や、それらの共重合体のモノマーとして使用することができる。
例えば、ポリイミドを製造する場合では、前記組成物と所定の酸無水物と反応させることで得ることができる。反応させる条件は、公知の方法を使用でき、例えば適当な温度と時間で加熱処理して付加反応を進行させればよい。この加熱処理時間は1時間~12時間実施することが好ましい。一例としては、60℃で4時間加熱処理する例が挙げられる。加熱処理温度としては、40℃以上100℃以下が好ましい。
各合成例にて得られた組成物10mgを、10mLメスフラスコに秤量後、テトラヒドロフラン2mLを添加して溶解させたのちに、アセトニトリルで定容したものを試料溶液とした。
