## Abstract 1,2‐Syndiotactic polybutadiene was synthesized at βˆ’30Β°C using the catalyst system CrCl~2~(dmpe)~2~‐MAO. The syndiotactic index of the butadiene sequences, expressed as a percentage of syndiotactic pentads [rrrr], was evaluated by ^13^C‐NMR measurements. WAXD and SAXS techniques were emp
