Description
ポリ酢酸ビニル含有量は、1gの物質をケン化するのに必要な量の消費から得られるアセチル基の割合(パーセント表示)を意味するものと理解されるべきものである。
約2gの被験物質を、1mgの精度で500mlの丸底フラスコに量り入れ、エタノール90mlとベンジルアルコール10mlに還流下で溶解させる。冷却後、溶液をフェノールフタレインを用いて0.01NのNaOHで中性に調節する。次いで、0.1NのKOHを25.0ml添加し、還流下、1.5時間加熱する。フラスコを閉じた状態で冷却し、過剰のアルカリを、指示薬としてのフェノールフタレインを用いて0.1Nの塩酸で、不変に脱色するまで滴定する。対照試料を同様に処理する。ポリ酢酸ビニル含有量を、以下のように計算する:
ポリ酢酸ビニル含有量(%)=(b−a)×86/E(aは試料に対する0.1NのKOHの消費量をmlで示し、bは対照試験に対する0.1NのKOHの消費量をmlで示し、Eは量り入れた被験物質の乾燥状態における量をgで示す)。
ポリビニルアルコール含有量は、その後の無水酢酸でのアセチル化によって検出可能な、パーセント表示によるヒドロキシル基の割合である。
Mowital約1gを、1mgの精度で300mlの三角フラスコに量り入れ、無水酢酸−ピリジン混合物(23:77v/v)を10.0ml添加し、15〜20時間にわたって50℃まで加熱する。冷却後、ジクロロエタンを17ml添加し、フラスコを少しの間回転させる。次いで、8mlの水を攪拌しながら添加し、フラスコを栓で閉じて10分間攪拌する。フラスコの首の部分と栓を50mlの脱イオン水ですすぎ、5mlのn−ブタノールの層を導入し、遊離の酢酸を、フェノールフタレインを用いて1Nの苛性ソーダ溶液で滴定する。対照試料を同様に処理する。ポリビニルアルコール含有量を、以下のように計算する:
ポリビニルアルコール含有量(%)=(b−a)×440/E(aは試料に対する1NのNaOHの消費量をmlで示し、bは対照試料に対する1NのNaOHの消費量をmlで示し、Eは量り入れた被験物質の乾燥状態における量をgで示す)。

使用したバインダー:Mowital B45H(Kuraray Specialities Europe GmbH)=V2
使用したバインダー:実施例6に沿ってエポキシプロパンで変性したB45H
使用したその他の材料
キャスティングスリップの製造を、当業者に既知の様式で行う。
・溶媒および分散剤(魚油)を量り入れる
・粉末の添加(解凝集)
・バインダーと可塑剤の添加(均質化、脱気)
a)バインダー溶液のレオロジー挙動
測定方法:レオロジー特性の測定のため、当該ポリマーの10質量%の溶液を、エタノール/トルエンの共沸溶媒混合物中で製造し、24時間にわたってタンブルミキサー中で均質化した。
測定方法:バインダーの分散効果を評価するため、さまざまなAl2O3懸濁液(エタノール/トルエンの共沸混合物40重量%、Al2O360重量%)を調製した。当該バインダーおよび/または分散剤を、徐々にその中に添加し、数時間にわたって均質化した。フィルムの調製の間に、分散剤(この場合、PVB)を溶媒中に予備溶解させ、その後、粉末を添加した。当該懸濁液を、回転式粘度計によって解析した。せん断速度100(1/s)での懸濁液の粘度を、基準値として使用した。
上記のようにして製造した懸濁液(キャスティングスリップ)を脱気し、長さ4mのフィルムキャスト設備で、固定ダブルチャンバー式キャスト装置を使用して、ドクターブレード法に従ってキャストした。シリコン処理PETフィルム(厚み100μm)をキャスト基材として使用した。キャスト後、フィルムを48時間にわたって空気中で乾燥させ(温度=22℃;大気湿度=65%)、続いて引き剥がした。
