Abstract
A process for effectively producing an alpha-olefin homopolymer or copolymer of two or more of alpha-olefins without using a great amount of an aluminum compound, is disclosed. In the process for producing a cyclic olefin based polymer according to the present invention, homopolymerization of an alpha-olefin or copolymerization of two or more of alpha-olefins is effected in the presence of a catalyst comprising, as main ingredients, the following Compounds (A), (B) and (C): (A) a transition metal compound; (B) a compound capable of forming an ionic complex when reacted with a transition metal compound; and (C) an organoaluminum compound.
