PRODUCTION OF POLYOLEFIN
PURPOSE:To obtain a polyolefin having a high bulk density, a large average particle diameter and excellent flow, by polymerizing an olefin using a catalyst comprising a specified solid catalyst component and an organometallic compound. CONSTITUTION:A solid catalyst component is obtained by mixing, w...

| description | PURPOSE:To obtain a polyolefin having a high bulk density, a large average particle diameter and excellent flow, by polymerizing an olefin using a catalyst comprising a specified solid catalyst component and an organometallic compound. CONSTITUTION:A solid catalyst component is obtained by mixing, with heating, 1g of an Si oxide and/or an Al oxide with 0.01-5g of a reaction product obtained by reacting a magnesium halide with a compound of formula I (wherein Me is an element of Groups I -IV of the periodic table, z is the valence of element Me, n is a number in the range: 0 |
