Title: Method for polymerizing olefin
Inventor: ISHIHAMA YOSHIYUKI
IPC: C08F4/6592
Filed: 2002-06-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for polymerizing an olefin in the presence of a specific polymerization catalyst having a high polymerization activity, by which a continuous polymerization operation in an industrial scale over a long period can be realized. SOLUTION: This method for polymerizing the olefin comprises polymerizing or copolymerizing the olefin in the presence of an olefin polymerization catalyst comprising [A1] a hafnium compound or zirconium compound having at least one conjugated five- membered ring ligand, [A2] a compound which is a zirconium compound having at least one conjugated five-membered ring ligand and is different from [A1], and [B] a sheet silicate. Since the catalyst has a high olefin polymerization activity, the catalyst quickly increases its particle diameter in a reactor so that a fine powder trouble to coagulate and adhere can be reduced. Further, since the catalyst does not cause the crush of particles, the industrial stable polymerization operation can be realized for a long period.  Since the catalyst scarcely contains low active particles, polymer particles having low melting points are not produced. The distribution of the melting points of the individual polymer particles is therefore narrowed. Consequently, a molded article having excellent composition uniformity can be produced, and the fine powder troubles such as the coagulation and the adhesion can be reduced. The industrial stable operation can be realized for a long period. In addition, when the obtained olefin polymer is subjected to a film-forming process, a blow-molding process, an injection molding process, or the like, the molded product hardly having gel, fish eye, and the like and having an excellent appearance can be obtained.
