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。
The effects of some impurities in butadiene produced by oxidative dehydrogenation of butene on the catalytic activity of the polymerized butadiene and the molecular weight of the polymer were investigated. Impurities generally reduce the catalytic activity, although their effects differ to a large extent. The molecular weight of the polymer increases with decreasing catalytic activity.
