Abstract
Description
−1%のPVAを水に溶解させた。
−PVCを上記溶液に添加した後、8時間50℃で乾燥させた。
−上記PVC/PVA混合物へ、DOP(フタル酸ジオクチル)、ステアリン酸亜鉛及びステアリン酸カルシウムを添加し、ドライブレンドした。
−得られた混合物60gを、5分間160℃でオープンロールを用いて粉砕した。
SC−T(P)、SM−T(P)、ver8.00ソフトウェアーと共に、直径30mmの試料ホルダー窓を取り付けた色差計(SM−T−H1型カラーコンピューター、スガ試験機株式会社)を使用して、白色度を測定した。
ビニルアルコールポリマーの0.1重量%水溶液を測定試料として作成した。この測定試料について、光学的距離1cmで280nm及び320nmの波長における吸光度を測定した。UV分光光度計(株式会社島津製作所製;UV2100)を測定に使用した。
ビニルアルコールポリマーの製造
ビニルアルコールの製造例を以下に記載する。まず、酢酸ビニル2400g、メタノール600g及びアセトアルデヒド32.5gを反応容器に供給した。その後、窒素ガスでバブリングすることによって、前記反応容器内の空気を窒素で置換した。次に、反応容器の温度を上げた。内部温度が60℃に達したとき、2,2’−アゾビスイソブチロニトリル1.0gを反応容器に添加することにより、重合を開始した。重合中、重合温度を60℃に維持した。重合開始から4時間後に、容器を冷却して重合を停止した。この時点で、コンバージョンは50%であった。続いて、一定間隔でメタノールを添加しながら、減圧下30℃で未反応の酢酸ビニルモノマーを反応溶液から取り除いて、ポリ酢酸ビニルのメタノール溶液(濃度50%)を得た。
ビニルアルコールポリマーの製造
得られたポリビニルアルコールを空気中6時間130℃で熱処理した以外は製造例1と同様にして、ビニルアルコールポリマー(実施例2)を製造した。
ビニルアルコールポリマーの製造
酢酸ビニルの重合においてアセトアルデヒドを使用しなかった以外は製造例1と同様にして、ポリビニルアルコール(比較例1)を製造した。重合度が750となるように、酢酸ビニル及びメタノールの量を変化させた。
ビニルアルコールポリマーの製造
得られたポリビニルアルコールを熱処理しなかった以外は製造例1と同様にして、ポリビニルアルコール(比較例2)を製造した。
表2から分かるように、本発明に係る変性ポリビニルアルコールは、従来技術から知られるポリビニルアルコールと比較して、改善された安定化効果を有する。
