    • This disclosure is to provide a method for preparing a terminal-modified conjugated diene polymer which achieves an extremely high compounding amount of cis-1,4 without complicated preparing conditions, a terminal-modified conjugated diene polymer obtained via the method, a rubber composition containing the terminal-modified conjugated diene polymer, and a tire using the rubber composition. This disclosure is A method for preparing a terminal-modified conjugated diene polymer comprising: polymerizing a conjugated diene compound by using a polymerization catalyst composition and modifying a polymer obtained via the polymerization by using a modifier, wherein the polymerization catalyst composition contains a rare earth element compound, and a coordination compound having a cyclopentadiene skeleton selected from substituted or unsubstituted cyclopentadienes, substituted or unsubstituted indenes, and substituted or unsubstituted fluorenes, and wherein the polymerization and modification is performed in a one-pot way.
    • 本发明提供一种制备在没有复杂的制备条件下实现极高配合量的顺式-1,4的末端改性共轭二烯聚合物的方法,通过该方法获得的末端改性共轭二烯聚合物,含有 末端改性共轭二烯聚合物,以及使用该橡胶组合物的轮胎。 本发明是一种制备末端改性的共轭二烯聚合物的方法,其包括:通过使用聚合催化剂组合物聚合共轭二烯化合物,并使用改性剂改性通过聚合获得的聚合物,其中所述聚合催化剂组合物包含稀土元素 化合物和具有选自取代或未取代的环戊二烯,取代或未取代的茚和取代或未取代的芴的环戊二烯骨架的配位化合物,并且其中聚合和改性以一锅法进行。
