## Abstract The polymerization of styrene by __n__‐butyllithium and titanium tetrachloride has been examined. Isotactic polystyrene is obtained only when 3.00 > __n__‐BuLi/TiCl~4~ > 1.75. At ratios less than 1.75 and greater than 3.00 only amorphous polystyrene (soluble in MEK) was formed. The mole
The polymerization of styrene catalyzed by n-butyllithium has been carried out in the presence of carbon black at 0°C in toluene. A large portion of the catalyst was consumed by the reaction with the carbon black surface and thus the growth of polystyrene anions on the surface was hindered to a cons
