| 摘 要： | 探讨了丁烯氧化脱氢生产丁二烯中出现的某些杂质对稀土催化体系聚合丁二烯的催化活性和聚合物分子量的影响。杂质普遍地降低了催化活性,尽管它们的影响在程度上是有很大的差别。聚合物的分子量随着催化活性的降低而升高。 |

| Abstract: | The effect of some impurities contained in butadiene produced by the oxidation-dehydrogenation of butene was studied in its polymerization with rare-earth catalytic system. In all cases, the catalytic activity decreased as the amount of the impurity was increased and the effect was in varying degrees with individual impurities. The molecular weight of the polymers obtained increased with decrease in catalytic activity. |
