## Abstract Diblock copolymers of α‐methylstyrene and butadiene were synthesized, using __n__‐BuLi as initiator, toluene as solvent, and tetrahydrofuran (THF) as accelerator. The addition of a small amount of THF in polymerization solution would greatly increase the 1,2‐addition of polybutadiene. H
