PROCESS FOR THE PRODUCTION OF POLYMERS CONTAINING CYCLIC OLEFINS

摘要

The invention relates to a process for the production of polymers containing cyclic olefins by contacting, under polymerisation conditions, at least one cyclic and/or polycyclic olefin, optionally in the presence of alpha -olefins, with a catalyst comprising a transition metal complex and a co-catalyst. The invention is characterized in that the transition metal complex consists of a reduced transition metal, chosen from groups 4-6 of the Periodic Table of the Elements, with a multidentate monoanionic ligand and with two monoanionic ligands. In particular the reduced transition metal is titanium (Ti).
