実施例1において、EGDMAの量を1.9g(2.33重量%)に変更したが、21時間後に反応容器中でゲルとなり、共重合体溶液が得られなかった。
実施例1において、MAAが用いられなかった。すべての共単量体の転化率が99%以上であり、共重合反応されていることを確認した。
実施例1において、EGDMAが用いられなかった。すべての共単量体の転化率が99%以上で、共重合反応されていることを確認した。
実施例1において、MAAおよびEGDMAが用いられなかった。すべての共単量体の転化率が99%以上で、共重合反応されていることを確認した。
共重合体溶液に、C4F9OC2H5および1,3-ビス(トリフルオロメチル)ベンゼンを加えて、その固形分濃度を2重量%に希釈し、その希釈液1mlをいずれも2×5cmのアルミニウム板に滴下し、スピンコートした後、120℃で10分間乾燥させて、試験片を作製した。
防錆性評価は、塩水噴霧試験(JIS Z 2371)により行った。基材としては、70×150×1.0mmのアルミニウム、銅またはSPCC試験片を用い、各含フッ素共重合体のC4F9OC2H5および1,3-ビス(トリフルオロメチル)ベンゼンの混合溶液(7:3v/v)に浸漬させ、試験片の表面処理を行った。得られた塗布試験片を、加工無しとした。また、加工無し試験片の塗膜に、カッターで試験片の対角線方向に2本傷付けたものを、クロスカットありとした。
-加工無し-
〇:錆発生無し
△:点錆が数か所で発生
×:観察面積の10%以上で錆が発生
-クロスカットあり-
〇:カット部から錆の拡がりが最大2mm以下
△:カット部から錆の拡がりが最大5mm未満
×:カット部から錆の拡がりが最大5mm以上
防湿性は、透湿度(カップ法、JIS Z 0208)により評価を行った。ポリイミドフィルムに製膜し、得られた膜を剥がして評価サンプルとした。実施例1の透過度(g/m2・24H)は、190であった。
