摘要：

When butadiene is polymerized in dichloroethane using dibutyl magnesium plus neodymium versatate as catalyst, high-trans polymer is formed during the first few hours of polymerization, followed by slow polymerization of the remaining butadiene to high-cis polymer after 7-8 h. This change probably occurs as a result of slow reaction between catalyst and solvent.
