Abstract:The polymerization of 1,3-conjugated dienes is the important part of
   polymer industry,and the fundamental element of synthetic rubber
   industry. Rare-earth-metal system is one of the most popular catalyst
   systems which conduct cis-1,4-polymerization of 1,3-conjugated dienes.
   Comparing with Li-system and Ti-system,rare-earth-metal system has
   unique advantages. With the further research,the research field of
   rare-earth-metal systems extended from heterogeneous systems to
   homogeneous systems or quasi-homogeneous systems. Different kinds of
   poly(dienes) with required molecular weight and molecular weight
   distribution could be made. With survey the publications during the past
   decade,the rare-earth-metal catalyst systems for conjugated dienes
   polymerization,which were classified into three parts,are reviewed in
   this article.
