      It was confirmed that lithium phenoxide could associate with the active center to block the inserting tunnels in anionic polymerization. With lithium phenoxide, the stability of n-BuLi in THF at 0°C was greatly improved. Due to the steric hindrance effect, the lithium phenoxide could diminish the polymerization rate in the polymerization of both St and MMA. In the polymerization of Ip with lithium phenoxide, it was found that the formations of 1,2- and 1,4-configurations were impeded, while the formation of 3,4-configuration was promoted.
