A method for controlling anionic polymerization, wherein initiator association complexes are directly or by means of a solution added into monomers or initiators simultaneously or respectively at different moment or in different stages for anionic polymerization; metallic atoms of the initiator association complexes are associated with cations of the initiator; limitation of the polymerization speed is realized by utilization of oxyl with large volume or large steric hindrance to limit a monomer addition channel, and side reaction is inhibited; and the polymerization temperature is controlled and adjusted, and anionic polymerization can be performed when the polymerization temperature is raised to the room temperature or a higher temperature, wherein the mole ratio of the initiator association complexes to the initiator is between 0.01:1 and 20:1. |
