PROCESS FOR PRODUCING CYCLIC OLEFIN BASED POLYMERS, CYCLIC OLEFIN COPOLYMERS, COMPOSITIONS AND MOLDED ARTICLES COMPRISING THE COPOLYMERS

摘要

Disclosed are a method for efficiently producing a cyclic olefin polymer and a cyclic olefin-α-olefin copolymer which are polymerized without opening a cyclic olefin.;Moreover, the cyclic olefin-alpha-olefin copolymer of the deep core obtained by the said method, the composition using this copolymer, and the molded article were disclosed. In the method for producing a cyclic olefin polymer of the present invention, a catalyst having the following compounds (A) and (B) as a main component or a homopolymerization of cyclic olefins or copolymerization of a cyclic olefin and an α-olefin, or the following compounds (A) and (B) And (C) using a catalyst as a main component.;(A) transition metal compound;(B) a compound that reacts with a transition metal compound to form an ionic complex;(C) organoaluminum compound
