摘要: 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(NdCl3·2Phen)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。

Abstract: The kinetics of butadiene polymerization with NdCl3.2Phen-HAl(i-Bu)2 system(Phen=1, 10-phenanthroline)has been studied. The results show that the rate of polymerizationis first order to both concentrations of monomer and neodymium complex, but 1/3 order with respect to the concentration of HAl(i-Bu)2.The number of active center and the apparent activation energy of butadiene polymerization with this system were derermined.
