    摘要： The present invention relates to a tin-containing organolithium compound which can be used as anionic polymerization initiators, represented by the following formula (1): R4−xSn(Ya—Zm—Yb—Li)x  (1) Wherein R, Z and Y are defined as in the specification; x represents a value of 1 or 2; m represents a value of 0 or 1; a represents a value of 0 to 6, b represents a value of 0 to 6, a+b is from 0 to 6, provided that m=1 when x=1. The tin-containing organolithium compounds according to the present invention can be used as initiators to initiate the polymerization of conjugated dienes and/or monovinyl aromatic hydrocarbons, thereby synthesizing various linear, star or telechelic polymers. The present invention also relates to a method for preparing the tin-containing organolithium compounds according to the present invention.
