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 ANGSTROM , 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 ANGSTROM , 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 DEG C is 30 wt.% or less.
