Description
更に本発明は、アニオン性基が、カルボン酸エステル、カルボン酸及びカルボン酸金属塩からなる群のうちの少なくとも1種以上の官能性基であることが好ましく、アニオン性基を含有するビニル単位が、一般式(化4)〜(化6)からなる群のうちの少なくとも1種以上を重合又は共重合したものであることが好ましい。
重合方法としては、例えば、メタノール、エタノールあるいはイソプロピルアルコール等のアルコールを溶媒とする溶液重合や、乳化重合、懸濁重合も可能である。かかる溶液重合において酢酸ビニル単量体、及び、アニオン性基を含有するビニル単量体の仕込み方法は、一括仕込み、分割仕込み、連続添加等任意の手段を用いて良い。重合反応は、アゾビスイソブチロニトリル、過酸化アセチル、過酸化ベンゾイル、過酸化ラウロイルなどの公知のラジカル重合触媒を用いて行われる。又反応温度は50℃〜反応混合物の沸点程度の範囲から好適に選択される。
酢酸ビニル70部、メタノール30部及び酢酸ビニルに対して0.08%のアゾビスイソブチロニトリルを重合缶に仕込み、窒素置換後加熱して、マレイン酸モノメチル2.4部を連続に添加しながら沸点で重合し、重合率80%に達した時点で重合を停止した。次いで常法により未重合の酢酸ビニルを除去し、得られた重合体を水酸化ナトリウムで常法によりケン化してポリビニルアルコールを得た。得られたポリビニルアルコールにおける、アニオン性基を含有するビニル単位の共重合率、ケン化度、20℃における4質量%水溶液の粘度を、それぞれ表1に示した。
アニオン性基を含有するビニル単位の含有率は、NMRの測定結果より算出したものであり、ケン化度は、JIS K 6276「3.5ケン化度」に準じて測定したものである。
表1に示したアニオン性基含有ビニル単位、ケン化度、4質量%水溶液の粘度を有するアニオン性基含有ポリビニルアルコールを調整し、実施例1と同様の評価を行った。結果を表1に記載した。なお、表1において、アニオン性基含有ビニル単量体aはマレイン酸モノメチル、アニオン性基含有ビニル単量体bはマレイン酸ジメチル、アニオン性基含有ビニル単量体cはイタコン酸、アニオン性基含有ビニル単量体dはマレイン酸をそれぞれ表す。
Claims (3)
- マレイン酸モノメチル、マレイン酸ジメチル、イタコン酸から選ばれるアニオン性基を含有するビニル単位の共重合率が1〜10モル%、ケン化度が80〜89モル%、20℃における4質量%水溶液粘度が8〜20mPa・sのポリビニルアルコールを含有するフィルム。
- ポリビニルアルコールのアニオン性基を含有するビニル単位の共重合率が2〜5モル%であることを特徴とする請求項1記載のフィルム。
- ポリビニルアルコールのケン化度が83〜86モル%であることを特徴とする請求項1または請求項2記載のフィルム。
