均相稀土配位催化剂及其活性体结构的研究——Ⅰ.丁二烯在(CF3COO)2NdCl·EtOH-AlEt3体系中的聚合
INVESTIGATION OF THE HOMOGENEOUS SYSTEM BASED ON RARE EARTH COORDINATION CATALYST AND ITS STRUCTURE OF ACTIVE SPECIES Ⅰ. Polymerization of Butadiene in the Presence of (CF3COO)2 NdCl ·EtOH-Et3Al
【摘要】 合成了新的釹络合物。分析结果表明这一络合物为(CF3COO)2NdCl·EtOH。这一络合物与三乙基铝可组成均相催化体系使丁二烯聚合得到顺式1,4-含量为78—98%的聚丁二烯。
【Abstract】 A new type of neodymium complex was synthesized. The analytical results indicated that this compound is (CF3COO)2NdCl-EtOH. A homogeneous catalyst system was obtained from this complex combined with triethylaluminium and gave polybuta-diene containing cis-content from 78 to 98%.
