Title:
OLEFIN POLYMERIZATION CATALYST AND METHOD FOR PRODUCING POLYOLEFIN POWDER
Document Type and Number:
Japanese Patent JP2008144149
Kind Code:
A
Abstract:
To provide an olefin polymerization catalyst enabling the polymerization of a polyolefin powder having controlled particle shape to give a low bulk density and useful as a raw material for a porous material having low air-flow resistance and to provide a method for producing a polyolefin powder by using the catalyst.
The invention provides an olefin polymerization catalyst produced by supporting a specific titanium compound on a carrier produced by reacting a specific organic magnesium compound with a specific chlorinated silicon compound and applying mechanical shear stress to the obtained solid particle and a method for producing a polyolefin powder by using the polymerization catalyst.
