Description
まず、開始剤にBF3OEt2を用いて重合を行った。モノマー濃度0.3mol/L開始剤濃度5.0mmol/Lで、シュレンク管にモノマー溶液4.5mLと開始剤溶液0.5mLを順に注射器で注入して重合を開始した。トルエン中、0℃で重合を行ったところ、20分で重合率100%に達し、数平均分子量Mn=83,500、分子量分布(多分散度)Mw/Mn=4.38の比較的高分子量のポリマーを得た。
次に、リビング重合開始剤である二成分系開始剤(CH3CH(Oi−Bu)OCOCH3/SnBr4)を用いた重合では、シュレンク管にモノマー溶液4.0mL、開始剤溶液0.5mL、活性化溶液0.5mLをこの順で注射器を用いて注入し重合を開始した。トルエン中、2,6−di−tert−ブチルピリジン(DTBP)存在下、0℃、モノマー濃度0.3mol/L,CH3CH(Oi−Bu)OCOCH35.0mmol/L,SnBr42.0mmol/L,DTBP0.2mmol/Lで行った。重合は、48時間で重合率99%に達し、重合系にアンモニア水を少量加えたメタノールを2.0ml加えて停止した。
実施例1と同様な条件で重合したポリマー(数平均分子量Mn110,000、分子量分布Mw/Mn3.41)のガラス転移温度Tg(DSCにより測定)は室温より高く35℃であった。生成ポリマーの構造をスペクトルにより検討した。ビニル基のピークは完全に消失し、環状アセタール基の存在を示すピークはそのまま観測された。各ピークの、積分強度比の検討により、ポリビニルエーテルの全ての繰り返し単位に環状アセタールが存在することがわかった。また、このポリマーの熱分解温度は305℃であった。得られたポリマー(I)のH1−NMRチャート(測定条件:溶媒にCDCl3を用い室温で測定)を図1にしめす。
実施例1と同様にして得られたポリアセタールビニルエーテルを以下のようにして脱保護した。即ち、ポリアセタールビニルエーテル0.2538gを、1mol/Lに調整した塩化水素溶液20mL(THF/1,4−ジオキサン=15mL/5mL)に溶解し、そのまま室温で7日間反応させた。なお7日間に水を4〜5滴加える作業を4回行なった。その後、エバポレーターにより溶媒を除去しNMRを測定したところ、開環率は37%であった。
