## 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 __
Neodymium chloride tripentanolate catalysts of the general formula NdCl 3 ϫ nL with n ϭ 3, L ϭ 1-pentanol (II), 2-pentanol (III), and 3-pentanol (IV) were prepared by an alcohol interchange reaction between neodymium chloride n isopropanolate (I) with pentanols. These NdCl 3 tripentanolates (II-IV)
