SOLID CATALYST COMPONENT FOR OLEFIN POLYMERIZATION

摘要

A solid catalyst component for olefin polymerization which comprises a catalyst component comprising at least titanium and chlorine fixed onto a porous substance of which the pore volume, at a pore radius in a range of from 200 to 2,000 .ANG., is 0.3 cc/g or more, said pore volume is 35% or more of the pore volume at a pore radius in a range of from 35 to 75,000 .ANG., the average particle diameter is from 5 to 300 .mu.m, the geometrical standard deviation of the particle size distribution is 2 or less and the solubility in toluene at 100.degree.C is 30 wt.% or less.
