Abstract:
1. A catalyst for the polymerization of norbornene monomers, comprising (i) transition metal complex (A) represented by formula (1) wherein M represents one transition metal selected from the elements belonging to eight, nine or ten group of the periodic table for 1991, and R 1 , R 2 and R 3 independently represent a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms; R 4 represents a hydrogen atom or a hydrocarbon group having 1 to 20 carbon atoms; R 5 , R 6 , R 7 , R 8 and R 9 represent independently from each other a hydrogen atom, a halogen atom or a hydrocarbon group having 1 to 20 carbon atoms; and R 5 , R 6 , R 7 , R 8 and R 9 may bond to each other to form a ring structure, and (ii) cocatalyst (B) which is an ionic compound which can generate a cationic transition metal compound by reacting with transition metal complex (A) and a phosphine ligand (C).
