中文摘要	stereoselective polymerization of 1,3-pentadiene (1,3-pd) by using the ternary catalyst system neodymium versatate (nd(vers)(3))/alkylaluminium/al(i-bu)(2)cl was examined. both homogeneous and heterogeneous catalyst systems prepared in the presence or absence of 1,3-pd monomer during catalyst preparation were employed for 1,3-pd polymerization. the effects of the type of alkylaluminium, [al]/[nd] molar ratio, and polymerization temperature on polymerization behaviours were investigated in detail. syndiotactic polypentadienes with cis-1,4 content ranged from 48.4% to 832% depending on polymerization conditions were obtained. the compounded polypentadiene vulcanizate showed fairly good mechanical properties, demonstrating 1,3-pd and the resultant polypentadiene are both qualified as a conjugated diene monomer and a synthetic rubber for practical application, respectively.
