butene

• In part 3 , the in - situ copolymerization of ethylene was investigated by the combinations of the cobalt - based catalyst and the metallocene to prepare short - branched polyethylene . the major oligomers catalyzed by the cobalt - based catalyst 5 , 6 and 7 werel - butene , and the minor were 1 - hexene . the comonomer effects were also observed
  在双亚胺基吡啶钴配合物与茂金属复配催化乙烯原位共聚制备短支链支化聚乙烯中，合成了3种双亚胺基吡啶钴配合物，研究了反应条件对其催化乙烯齐聚活性和所得产物碳数分布的影响。
