Abstract

PURPOSE: To prepare an α-olefin polymer having improved crystallinity and bulk density, by using a catalyst comprising an aluminum compound, and electron donor and a composition provided by pulverizing a magnesium compound together with an organic acid ester, an unsaturated monomer, hydrocarbon, etc. and treating the mixture with a titanium compound.
CONSTITUTION: An α-olefin (e.g. propylene, etc.) is polymerized to give the desired polymer by using a polymerization catalyst comprising (A) a composition provided by pulverizing (a) a magnesium halide together with (b) an organic acid ester (e.g. ethyl benzoate, etc.), (c) an aromatic hydrocarbon having an unsaturated substiuent (e.g. α-methylstyrene, etc.), (d) a hydrocarbon (e.g. n-heptane, etc.), etc. and treating the mixture with (e) titanium tetrachloride at 80°C, (B) an organoaluminum compound (e.g. triisobutylaluminum, etc.) and (C) an electron donor, e.g. an organic acid ester or its complex with an aluminum halide, etc.
