## 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

## Abstract Polymerizations of butadiene, penta‐1,3‐diene, and isoprene with __n__‐butyl titanate–triethylaluminum catalyst are examined by ESR measurements on the polymerization state. At Al/Ti molar ratios greater than 2.9 where the conjugated dienes are polymerized, the polymerization system of
## Abstract 1,3‐Butadiene, 4‐methyl‐1,3‐pentadiene and styrene were polymerized with dicyclopentadienyltitanium dichloride/methylaluminoxane (Cp~2~TiCl~2~/MAO) and dicyclopentadienyltitanium chloride/MAO (Cp~2~TiCl/MAO). These systems are less active than cyclopentadienyltitanium trichloride/MAO (C
