摘要： The present invention relates to the field of olefin polymerization, and in particular relates to a catalyst composition and an application thereof. The catalyst composition of the present invention comprises the following components: a) a metallocene compound, b) a co-catalyst component, and c) a phenol, the co-catalyst component being a combination of an organoaluminum compound and an alkyl aluminoxane, or a combination of an organoaluminum compound and an organoboron compound. When the catalyst composition of the present invention is used for the copolymerization of ethylene and a cycloolefin or an alkenol, not only can the molecular weight of the polymer be increased, but the content of cycloolefin or alkenol structural unit in the copolymer can also be increased.
