氯化稀土的某些配合物与烷基铝组成的双烯烃定向聚合催化剂用于丁二烯聚合时,大多得到分子量较高的产物。最近我们报道了可在较宽范围内改变聚丁二烯分子量的三氯化钕邻菲啰啉配合物(NdCl_3·2Phen)与氢化二异丁基铝[HAl(i-Bu)_2]所组成的新的二元氯化稀土定向聚合催化剂。本文报导该体系下的丁二烯聚合动力学,测定了聚合反应速率对
Some rare earth chloride complexes and aluminum alkyl composed of two-oriented polymerization catalyst for the polymerization of butadiene, the higher the molecular weight of the product. Recently we reported the composition of neodymium trichloride phenoxide complexes (NdCl 3 · 2Phen) and diisobutylaluminum hydride [HAl (i-Bu) 2] that can change the molecular weight of polybutadiene in a wide range. Of the new binary rare earth chloride orientation polymerization catalyst. This paper reports the polymerization kinetics of butadiene under this system and the polymerization rate
