The invention relates to the field of catalysts, and discloses a non-metallocene compound and ethylene-styrene copolymer, a preparation method, a catalyst composition for olefin polymerization and applications thereof. The compound has a structure represented by formula (1). The catalyst composition for olefin polymerization of the present invention contains a main catalyst and a co-catalyst, the main catalyst is the aforementioned non-metallocene compound of the present invention, and the co-catalyst contains an aluminum-containing compound and optionally an organic boron compound. The aforementioned catalyst composition for olefin polymerization provided by the present invention has the advantage of high catalytic activity. When the catalyst composition for olefin polymerization of the present invention catalyzes the copolymerization of ethylene monomers and vinyl aromatic monomers, relatively high content of ethylene structural units can be obtained and A single ethylene-styrene copolymer, so that the toughness of the obtained copolymer is obviously better than that of the prior art. |
