Abstract
A solid catalyst for olefin polymerization is obtained by treating magnesium halide with a sulfur compound or sulfur and a sulfur compound and further treating with an electron donor compound and a halogen-containing titanium compound. Alternatively, the magnesium halide is treated with halogen and/or an interhalogen compound and sulfur and/or a sulfur compound and is further treated with an electron donor compound and a halogen-containing titanium compound. The solid catalyst thus obtained is used for a catalytic system for olefin polymerization in combination with an organometallic compound.
