Fund Project: This work was subsidized by the National Natural Science Foundation of China (No.20074040).

The initiation reactions in the anionic non-equilibrium polymerization of octamethylcyclotetrasiloxane (D₄) initiated by silazyllithiums were investigated. It was found that the structure of the substituents on the Si atom had great influences on the initiation activity of silazyllithiums.
