An organolithium compound represented by the following general formula (i): (i) [wherein A represents a heteroatom selected among oxygen, nitrogen, sulfur, and phosphorus; Ar represents optionally substituted aryl; R1 represents C1-10 alkyl; R2 represents C1-10 alkylene; R3 represents C1-10 alkyl or a protective group for the functional group -A-H (A is a heteroatom); and when the heteroatom A is oxygen or sulfur, then m and n each is 0 or 1, provided that the sum of m and n is 1, and when the heteroatom A is nitrogen or phosphorus, then m and n each is 0, 1, or 2, provided that the sum of m and n is 2], which has not hitherto been used in anionic polymerization, is used as an anionic polymerization initiator to easily and smoothly produce a polymer having a functional group at an end.
由以下通式(i)代表的有机锂化合物:(i) [其中 A 代表选自氧、氮、硫和磷的杂原子;Ar 代表任选取代的芳基;R1 代表 C1-10 烷基;R2 代表 C1-10 亚烷基;R3 代表 C1-10 烷基或官能团 -A-H 的保护基(A 为杂原子);当杂原子 A 为氧或硫时,则 m 和 n 各为 0 或 1,条件是 m 和 n 之和为 1;当杂原子 A 为氮或磷时,则 m 和 n 各为 0、1 或 2,条件是 m 和 n 之和为 2],迄今尚未用于阴离子聚合,用作阴离子聚合引发剂,可轻松顺利地生成末端具有官能团的聚合物。
