摘要 聚合物载体-稀土金属配合物的研究.聚(苯乙烯-4-乙烯基吡啶)钕配合物在丁二烯聚合中的催化行为李晓莉于广谦*李玉良(中国科学院长春应用化学研究所长春130022)关键词苯乙烯,乙烯基吡啶,共聚物,钕配合物,丁二烯聚合1996-04-11收稿,1996... The catalytic behaviour of poly(styrene 4 vinylpyridine)(PS4VPy) neodymium complex [(NdCl 3) n ·PS4VPy] for butadiene polymerization was described. The catalytic activity of (NdCl 3) n ·PS4VPy was much greater than that of similar small molecule catalysts. The catalytic efficiency of (NdCl 3) n ·PS4VPy was up to 11 7 kg polybutadiene/g Nd, about 25 times that of NdCl 3·1 5DPy which exhibited the highest activity among the corresponding small molecule catalysts. The relationship between the activity of (NdCl 3) n ·PS4VPy and its constitution was discussed. The activity of (NdCl 3) n ·PS4VPy increased as the molar ratio of 4 vinylpyridine(4VPy)/Nd decreased. High activity was found at 4VPy/Nd ratio about 2 with 88 ̄96% conversion. It is likely that uncoordinated 4VPy units remaining in the complex interact with the alkyl aluminium or active species to decrease the activity.
