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。
酸成分原料モノマーAとして、[化3]に示すナフタレン-1,4,5,8-テトラカルボン酸二無水物、及び、アミン成分原料モノマーBとして、[化1]に示すベンジジン-2,2’-ジスルホン酸を用い、上記形態に記載した工程条件にしたがって、図3に示す成膜装置の基板9上にスルホン酸化ポリイミド樹脂膜を形成した。
参考例1にて得られたスルホン酸化ポリイミド樹脂膜に対して、真空中、温度条件として300℃及び保持時間として1時間の条件下、熱イミド化処理を行った。処理後のスルホン酸化ポリイミド樹脂膜の赤外吸収スペクトルチャートを図4中の(2)に示す。1720cm−1(A2)、1680cm−1(B2)、1340cm−1(C2)近傍に、それぞれポリイミドに由来する吸収ピークが認められ、未反応だった酸無水物モノマーとポリアミド酸との反応が進行した結果、ポリイミドとして生成されたことが分る。一方、1500cm−1(D2)のベンジジン-2,2’-ジスルホン酸骨格に由来するピークが減少し、イミド化処理中に、未反応の酸成分モノマーが蒸発して失われたことが分る。
参考例1にて得られたスルホン酸化ポリイミド樹脂膜に対して、大気中、温度条件として150℃及び保持時間として16時間の条件下、加熱処理を行った。処理後のスルホン酸化ポリイミド樹脂膜の赤外吸収スペクトルチャートを図4中の(3)に示す。1780cm−1(A3)近傍の酸無水物に由来する吸収ピークが減少すると共に、1720cm−1(B3)、1680cm−1(C3)、1340cm−1(D3)近傍に、それぞれポリイミドに由来する吸収ピークが認められ、この温度にてアミン成分モノマー内で固相重合反応が進行したことが分る。
実施例1にて得られたスルホン酸化ポリイミド樹脂膜に対して、真空中、温度条件として300℃及び保持時間として1時間の条件下、熱イミド化処理を行った。処理後のスルホン酸化ポリイミド樹脂膜の赤外吸収スペクトルチャートを図4中の(4)に示す。1500cm−1(A4)のベンジジン-2,2’-ジスルホン酸骨格に由来するピークの変化は少ないが、酸無水物に由来する吸収ピークが消滅する一方、1720cm−1(B4)、1680cm−1(C4)、1340cm−1(D4)近傍に、それぞれポリイミドに由来する吸収ピークが認められる。よって、未反応だった酸無水物モノマーとポリアミド酸との反応が進行した結果、ポリイミドとして生成されたことが分る。
触針式膜厚計で測定した樹脂膜の膜厚は560nmであり、残存膜厚について上記記載を裏付けるものとなっている。
