Title:
ALPHA-OLEFIN POLYMERIZATION CATALYST AND PRODUCTION OF ALPHA-OLEFIN POLYMER
Document Type and Number:
Japanese Patent JP3885336
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a highly stereoregular α-olefin polymer with slight fine powder and good powder disposition, and to obtain a catalyst for α-olefin polymerization having high catalytic activity enough to dispense with removing catalyst residues and amorphous polymers.
SOLUTION: This catalyst for α-olefin polymerization is composed of (A) a titanium compound-contg. solid catalytic component which is prepared by the following process: a solid product formed by mutual contact between a Si-O bond-bearing organosilicon compound, an ester compound and an organomagnesium compound is treated with an ether compound, titanium tetrachloride and an organic acid halide compound followed by a mixture of an ether compound and titanium tetrachloride or a mixture of an ether compound, a titanium tetrachloride and an ester compound, (B) an organoaluminum compound, and (C) an electron-donating compound. The other objective method for producing an α-olefin polymer comprises homopolymerization of an α-olefin, or copolymerization between an α-olefin and ethylene or another α-olefin, using the above catalyst.
