(含フッ素エラストマーの重合)
磁力誘導攪拌装置を有する内容積3.0リットルの重合槽に、純水1.47L、10重量%のパーフルオロオクタン酸アンモニウム水溶液30gを供給した。系内を窒素ガスで充分置換したのち減圧状態にした後、内温を80℃にし、HFPを内圧が0.73MPaまで、さらにVdFを1.5MPaまで仕込んだ。攪拌下に、過硫酸アンモニウム塩(APS)0.114gを水8.1gに溶解し仕込み、重合を開始した。重合圧力を1.5MPaとし、重合時の圧力低下を補うため、VdF/HFP混合モノマー(78/22(モル%))の連続的に供給し、重合終了までに、300gのモノマーを槽内に供給した。途中、VdF/HFP混合モノマーを7g供給した時点で、オクタフルオロ−1,4−ジヨードブタン22.7g、重合開始後、3時間、6時間でそれぞれ、APS0.114gを水8.1gに溶解させた水溶液を追加で仕込んだ。反応時間は10時間1分であった。得られた乳濁液の重量は1851g、ポリマー濃度が17.7重量%であった。
参考例1で得られた含フッ素エラストマー23.3gをアセトニトリル120gに溶解させた溶液と、2,5−ジメチル−2,5−ジ(t−ブチルパーオキシヘキサン)(商品名:パーヘキサ25B 日本油脂(株)製)0.974g、イソシアヌル酸ジアリル 7.01g(含フッ素エラストマーのヨウ素含有量に対して5倍モル量)を磁力誘導攪拌装置を有する内容積0.3リットルのSUS製耐圧オートクレーブに入れ、−30℃で系内を窒素ガスで充分置換した後、窒素ガスで0.1MPaに加圧した。
参考例1で得られた含フッ素エラストマー25.6gをアセトニトリル120gに溶解させた溶液と、2,5−ジメチル−2,5−ジ(t−ブチルパーオキシヘキサン)(商品名:パーヘキサ25B 日本油脂(株)製)1.07g、ジアリルジメチルシラン5.17g(含フッ素エラストマーのヨウ素含有量に対して5倍モル量)を磁力誘導攪拌装置を有する内容積0.3リットルのSUS製耐圧オートクレーブに入れ、−30℃で系内を窒素ガスで充分置換した後、窒素ガスで0.1MPaに加圧した。撹拌下、内温を150℃にして、6時間加熱し、反応を終了した。
実施例1で得られた含フッ素エラストマーを0.115gと、架橋剤としてジメチル−メチルハイドロジェンポリシロキサン(25−30%メチルハイドロシロキサン)−(ジメチルシロキサン)共重合体(商品名:HMS−301、アヅマックス(株)社 GELEST,INC.製 分子量1900−2000)0.0195gをアセトン1.0gに溶解した後、白金の濃度が0.06%の白金触媒のトルエン溶液 0.011g(オーエムジープレシャスメタルズ・ジャパン(株)社製 Pt−VTSC−12.0VTSをトルエンで200倍に希釈した溶液)を添加して室温下で混合した溶液を作製した。この溶液をガラス製シャーレ上50℃で加熱し、溶媒のアセトンを蒸発させた後、さらに100℃で1時間、加熱したところ、粘性はないが、弾性のあるシート状の硬化体が得られた。
さらにこの硬化体は、アセトンに不溶であったため、硬化反応が進行したと考えられる。
実施例1で得られた含フッ素エラストマー10gを還流冷却管の付いた4つ口フラスコ中、禁水条件下で無水テトラヒドロフラン100gに溶解させ、撹拌しながら該フラスコ内容物の温度が80℃になるようにオイルバスにて加熱した。次に、フラスコ内に塩化白金酸のイソプロピルアルコール2%溶液1.0gを添加し、次いで滴下ロートからトリメトキシシラン0.4gを滴下して反応を行った。滴下終了後、80℃で5時間加熱還流を続けた後、テトラヒドロフランと未反応のトリメトキシシランを減圧下、加熱により除去した。得られたポリマーの1H−NMR分析では、実施例1の含フッ素エラストマーのアリル基由来のピークは認められず、トリメトキシシリル基由来のピークが3.5ppm付近に認められたので、含フッ素エラストマーに加水分解シリル基が導入されたと考えられる。
実施例4で得られた含フッ素エラストマー0.1gをアセトン1gに溶解し、ガラス板上に塗布した。アセトンを風乾により除去した後、100℃で5時間加熱した後、室温で24時間放置し、ガラス板上を観察したところ、粘着性はないが、弾性のある塗膜が形成され、この塗膜は、アセトンに浸漬しても溶解しなかったので、加水分解シリル基により硬化反応が進行したと考えられる。
