得られた共重合体をゲルパーミエーションクロマトグラフィー(移動相THF、ポリスチレンスタンダード)により分析したところ、重量平均分子量(Mw)は24,300、分子量分布(Mw/Mn)は1.28であることを確認した。また、組成比はPS/PB/PS=25/50/25重量%の共重合体であった。なお、PSは、スチレンブロックの意味であり、PBはブタジエンブロックの意味である。以下同様。
反応液を二回水洗後、溶媒を留去した。メタノールに再沈殿、ろ別し真空乾燥することで白色粉末を得た。1H-NMRにて算出したブタジエンブロック中の1,2結合構造は、93モル%であった。
500mLフラスコにTHF149.37g、ヘキサン17.53gを加えた。-40℃まで冷却後、n-ブチルリチウム5.21g(15.1重量%濃度ヘキサン溶液)を加え、10分間撹拌後、スチレン10.47gを滴下し、30分間反応を継続した。ガスクロマトグラフィー(以下GCと略す)を測定し、モノマー消失を確認した。次いで、1,3-ブタジエン49.28g、THF49.28gの混合液を滴下し、反応を継続した。GCを測定し、モノマー消失を確認した後、スチレン10.66gを滴下し、30分後メタノール1.12gを加えて反応を停止した。
