Abstract
A solid catalyst for olefin polymerization is obtained by treating magnesium halide with halogen or a halogen compound and further treating with an electron donative compound and a halogen-containing titanium compound. The halogen atom of the halogen or halogen compound as the treating agent must be different from the halogen atom of magnesium halide as the substrate. This solid catalyst is used for a catalytic system for olefin polymerization in combination with an organometallic compound.
