ABSTRACT:
This invention relates to a process for polymerizing polar substituted norbornenes and/or cycloalkenes, optionally, in the presence of another unsaturated compound. The method is characterized in that the polymerization is carried out in the presence of one or more tungsten carbine complexes.
