Abstract

PURPOSE: To manufacture polyolefins favorably on an industrial scale in high yield by the use of a polymerization catalyst comprising a magnesium compound, an alkoxymetallic compound, a silicone, and a titanium compound.
CONSTITUTION: The objective polyolefins can be obtained by polymerization of olefins in the presence of a catalyst consisting of A) a magnesium compound (e.g. magnesium chloride), B) an alkoxy group-containing metallic compound (the metal belonging to IWIV group of the periodic table) (e.g. lithium ethoxide), C) a silicone of formula (R' is hydrocarbon) (e.g. methyl hydropolysiloxane), D) a liquid halogen compound of titanium or vanadium (e.g. titanium tetrachloride), and, if required, E) an electron-donating compound.
