Abstract

PURPOSE: To prepare an α-olefin polymer having high degree of crystallinity and bulk density, by polymerizing an α-olefin in the presence of a catalyst composed of a component obtained by co-crushing a Mg compound, an organic acid ester, and aromatic compounds, and treating the co-crushed product with a titanium compounds, an organoaluminum compound, and an electron donor.
CONSTITUTION: An α-olefin (e.g. propylene) is polymerized by using a catalyst composed of (A) a composition obtained by (1) co-crushing (a) a magnesium halide, (b) an organic acid ester (e.g. ethyl benzoate), (c) an aromatic hydrocarbon compound having an unsaturated substitution group (e.g. α-methylstyrene), and (d) an aromatic ether compound (e.g. diphenyl ether), and (2) heat-treating the co-crushing product in the presence of titanium tetrachloride, (B) an organo-aluminum compound (e.g. triisobutyl aluminum) and (C) an electron donor selected from an organic acid ester and a complex of an organic acid ester and aluminum halide.
