• 英文摘要： GPC was used to determine the molecular weight distribution of the
  products from the polymerization of butadiene in toluene solution in a batch reactor
  using Ziegler-Natta type catalysts. The inadequacy of the existing calibration
  methods of GPC applying to polybutadiene has led to the development of a new
  technique of calibration using only broad polymer fractions. In the study of
  molecular weight distribution it was found that the TiI/sub 4/ concentration is the
  dominating factor to the molecular weight of the product, while the Al/Ti ratio
  tends to affect the shape of distribution curve. At high Al/Ti ratio the distribution
  curves show considerable tailing at low molecular weight end and eventually become
  bimodal.
