Abstract
【解決手段】官能化重合体は、重合体鎖と、一つ以上のウレタン基を含有する官能性を介して該重合体鎖に結合した末端基とを含む。上記官能化重合体は、求核試薬を末端イソ(チオ)シアネート官能性を有する重合体と反応させることによって提供でき、該末端イソ(チオ)シアネート官能性を有する重合体は、順に、活性末端重合体をポリイソ(チオ)シアネートで反応させる。かなりの量のスチレン単量体単位を含有する重合体でさえも、上述の方法に用いることができる。
【選択図】なし

攪拌機を備え、N2でパージした反応装置に、ヘキサン1.75kg、スチレン溶液0.76kg及びブタジエン溶液1.98kgを加えた。その反応装置にn-ブチルリチウム3.2mLとKTA0.32mLとを投入し、次いで2,2-ビス(2'-テトラヒドロフリル)プロパン溶液0.17mLを投入した。反応装置のジャケットを約82℃に加熱し、約22分後、バッチ温度が約91℃でピークに達した。50℃にて更に約30分後、重合体セメント(色はピンクであった)を反応装置から乾燥ガラス容器に移した。
試料10:脱イオン水0.4mL(3×)
試料11:N-[3-(トリメトキシシリル)プロピル]エチレンジアミン(ヘキサン中1.0M)0.45(4×)mL
