A method for producing a functionalized polymer, the method comprising the steps of: (i) preparing a bulk polymerization system including a reactive polymer by introducing a lanthanide-based catalyst and a conjugated diene monomer; (ii) adding a heterocyclic nitrile compound the polymerization system including the reactive polymer to prepare polymerization system including a functionalized polymer; and (iii) adding a protic compound to the polymerization system including a functionalized polymer where the ratio of water or protic hydrogen atoms in the protic compound to the lanthanide atoms in the lanthanide-based catalyst is at least 1500 to 1.
一种生产官能化聚合物的方法,该方法包括以下步骤(i) 通过引入镧系催化剂和共轭二烯单体,制备包括反应性聚合物的大块聚合体系; (ii) 向包括反应性聚合物的聚合体系中加入杂环腈化合物,制备包括官能化聚合物的聚合体系; 以及 (iii) 向包括官能化聚合物的聚合体系中加入原生化合物,其中原生化合物中的水或原生氢原子与镧系催化剂中的镧系原子之比至少为 1500 比 1。
