CHROMIUM COMPLEX, CATALYST FOR PRODUCING ETHYLENE-BASED POLYMER AND METHOD FOR PRODUCING ETHYLENE-BASED POLYMER

摘要

PROBLEM TO BE SOLVED: To provide a new chromium complex containing, as a ligand, a group having a binaphthyl skeleton useful as a catalyst component for producing an ethylene-based polymer, to provide a catalyst for producing an ethylene-based polymer using the complex, and to provide a method for producing an ethylene- based polymer using the catalyst.;SOLUTION: This chromium complex comprises a group having a binaphtyl skeleton represented by the general formula (1) (wherein, R¹ to R¹² may be the same or different and are each H, a 1-20C alkyl or aryl, or a silyl substituted by a 1-20C alkyl or aryl; and X is O, N, S or P) as a ligand, the catalyst for producing ethylene-based polymer comprises the chromium complex and an organic aluminum, and the method for producing the ethylene-based polymer comprises using the catalyst.;COPYRIGHT: (C)2003,JPO
