Abstract
【解決手段】四カルボン酸二無水物と、スルホン酸基含有のジアミン化合物とをそれぞれ原料モノマーとする蒸着重合反応によりスルホン酸化ポリイミド樹脂の成膜を行う。この際、蒸着重合反応前に、前記スルホン酸基含有ジアミン化合物に対して、真空中70〜300℃の温度範囲にて脱水処理を行うことが望ましい。あるいは、蒸着重合反応に際して、スルホン酸基含有ジアミン化合物の蒸発温度を該アミン化合物の固相重合温度以下とすることが望ましい。また、蒸着重合反応により成膜されたスルホン酸化ポリイミド樹脂に対して、さらに、70〜180℃の温度範囲及び保持時間1時間以上にて、熱イミド化処理をおこなうことが望ましい。
【選択図】図3
Description
(1)アミン化合物は吸水率が高く、蒸着工程中にガス放出が認められ、安定した化 学量論的組成比の重合反応生成物を得ることが難しい。
(2)ジアミン化合物の蒸発温度を上昇させると、蒸発源内において自己重合反応が 生じ、逆に蒸発速度が低下してしまうことがあり、反応制御が難しい。
a)自己重合反応に関して(右軸の示差熱分析参照)
370℃近傍 :固相重合による吸熱ピークが認められる。
b)重量減少に関して(左軸の重量測定参照)
室温〜100℃ :含有水分の脱水による急減な重量減少が生じる。
100〜300℃:脱水による重量減少がなだらかに推移する。
320℃〜 :ジアミン化合物の蒸発による重量減少が始まる。
370℃〜 :固相重合開始に伴い、モノマー蒸発による重量減少が減速する。
また、図2は
a)自己重合反応に関して(右軸の示差熱分析参照)
390℃近傍 :固相重合による吸熱ピークが認められる。
b)重量減少に関して(左軸の重量測定参照)
室温〜150℃ :含有水分の脱水による急減な重量減少が生じる。
360℃〜 :ジアミン化合物の蒸発による重量減少が始まる。
390℃〜 :固相重合開始に伴い、モノマー蒸発による重量減少が減速する。
次に、バルブ5、6を閉じた状態で、蒸発容器7、8にそれぞれ備えた図外の加熱ヒータにより、蒸発容器7、8内の酸成分原料モノマーA及びアミン成分原料モノマーBをそれぞれ蒸発温度以上(例えば、原料モノマーA:230℃、及び、原料モノマーB:340℃)にて加熱する。そして、バルブ11を閉じると共にバルブ5、6を開放した状態とし、原料モノマーA、Bを昇華させ、基板9上での蒸着重合を開始する。さらに、所定の反応時間(例えば約20分間)経過後に、バルブ5、6をともに閉じ、真空槽容器1内を大気圧に開放した後に基板9を取り出して、蒸着重合工程の終了とする。
