Abstract

Various 1,3‐dienes (1,3‐butadiene, isoprene, 2‐ethyl‐1,3‐butadiene, (E)‐ and (Z)‐1,3‐pentadiene, (E)‐2‐methyl‐1,3‐pentadiene) were polymerized with the soluble catalyst system methylaluminoxane/V (acac)~3~ (acac: acetylacetonato). Butadiene and (Z)‐1,3‐pentadiene gave trans‐1,4 polymers, at low and room temperature. Isoprene, 2‐ethyl‐1,3‐butadiene and (E)‐2‐methyl‐1,3‐pentadiene gave trans‐1,4‐polymers at low temperature (< −20°C), but polymers of mixed cis/trans structure at room temperature. (E)‐1,3‐pentadiene gave polymers of mixed 1,2/trans‐1,4 structure either at low or room temperature. An interpretation of the results is reported.
