Description
本実施例では、ポリビニルベンジルクロライド(poly(St-CH2Cl))をシリカ粒子の表面にグラフト重合し、次いでトリブチルホスフィンを反応させることにより、シリカ粒子の表面へ四級ホスホニウム塩基を有するポリマーをグラフト重合した。なお、ポリビニルベンジルクロライド(poly(St-CH2Cl))のグラフト重合は、シリカ粒子の表面へ導入したトリクロロアセチル基とモリブデンヘキサカルボニル(Mo(CO)6)とを組み合わせた系により行った。
アミノ基を導入したシリカ粒子(Silica-NH2:日本アエロジル株式会社製、粒子径12nm、表面積200m2/g、アミノ基の導入量0.29mmol/g)4.0g、イソシアン酸トリクロロアセチル1.0g、反応溶媒としてトルエン(金属ナトリウム上で8時間還流した後、常圧蒸留したもの)200mLを300mLナス型フラスコに加え、系内を窒素置換し、マグネチックスターラーで攪拌しながら80℃で8時間反応させた。反応後、THFを用いて遠心分離による洗浄を繰り返し行い、減圧乾燥した。
重合封管中に、トリクロロアセチル基を導入したシリカ粒子0.20g、4−ビニルベンジルクロライド(St-CH2Cl:窒素雰囲気下で減圧蒸留したもの)0.4g、モリブデンヘキサカルボニル(Mo(CO)6)0.01g、反応溶媒としてDMSO(水素化カルシウムで一日脱水した後、窒素雰囲気下で減圧蒸留したもの)10mLを加え、ドライアイス/メタノール中でモノマーを完全に固化させた後、系内を真空にし、ついで融解させた。この操作を3回繰り返し、高真空下で封管とした。これをマグネチックスターラーで撹拌しながら70℃で一定時間重合を行った。反応後、生成物を過剰のメタノール中に注ぎ、反応を停止させた。
三方コックおよび玉付きコンデンサーをつけた100mL三口フラスコに上記のグラフト重合したシリカ粒子5.0gを加え、系内を完全に窒素置換した後、シリンジを用いてトルエン40.0mL、シリカ粒子にグラフト重合したポリビニルベンジルクロライド(poly(St-CH2Cl))のクロロメチル基に対して過剰量のトリ−n−ブチルホスフィン5.0mLを注入した。系内をマグネチックスターラーで撹拌しながら室温で48時間攪拌し、その後還流しながら24時間反応を行った。反応後、トルエンを用いて遠心分離による洗浄を繰り返し行い、デシケーター内で減圧乾燥させた。
本実施例では、四級ホスホニウム塩基を有するモノマーとしてトリブチルビニルベンジルホスホニウムクロライド(St-CH2P(C4H9)3Cl)を合成した後に、シリカ粒子の表面からポリマーを成長させた。なお、トリブチルビニルベンジルホスホニウムクロライド(St-CH2P(C4H9)3Cl)を用いたグラフト重合は、シリカ粒子の表面へ導入したトリクロロアセチル基とモリブデンヘキサカルボニル(Mo(CO)6)とを組み合わせた系により行った。
三方コックをつけた200mL三口フラスコ内を窒素置換し、トリブチルホスフィン35.5mL、ヘキサン(金属ナトリウム上で8時間還流した後、常圧蒸留したもの)60.0mLをシリンジを用いて注入し、マグネチックスターラーで撹拌しながらビニルベンジルクロライド(St-CH2Cl)33.4mLをシリンジを用いてゆっくりと滴下し、室温で24時間反応させた。反応後、ヘキサンを用いて遠心分離による洗浄を繰り返し行い、トルエンで再結晶し、デシケーター内で減圧乾燥させた。
重合封管中に、トリクロロアセチル基を導入したシリカ粒子0.20g、トリブチルビニルベンジルホスホニウムクロライド(St-CH2P(C4H9)3Cl)0.9g(2.7mmol)、モリブデンヘキサカルボニル(Mo(CO)6)0.01g、反応溶媒としてDMSO(水素化カルシウムで一日脱水した後、窒素雰囲気下で減圧蒸留したもの)10mLを加え、ドライアイス/メタノール中でモノマーを固化させた後、系内を真空にし、ついで融解させた。この操作を3回繰り返し、高真空下で封管とした。これをマグネチックスターラーで撹拌しながら70℃で一定時間重合を行った。反応後、生成物を過剰のTHFまたはアセトンに注ぎ、反応を停止させた。
実施例1で合成した抗菌剤を用いて、抗菌性発泡樹脂を作製した。
実施例1で合成した抗菌剤とポリスチレンとの複合体膜を作成し、その表面の抗菌性を調べた。
実施例1で合成した抗菌剤とポリスチレンとの複合体膜を作成し、この複合膜からの、水中における抗菌剤の溶出試験を行った。
