Abstract
PURPOSE: To produce a highly crystalline polymer in the form of well-shaped particles in high yields, by polymerizing an α-olefin in the presence of a catalyst obtained by preactivating the reaction product obtained by the reaction of an organic Al compound, an electron donor, titanium tetrachloride, etc.
CONSTITUTION: A solid product is obtained by reacting 1mol of an organic Al compound such as triethylaluminum with 0.15W2mol of an electron donor such as ethanol, reacting the reaction product with titanium tetrachloride in the presence of an aromatic compound such as benzene, and reacting further the product with 1W 7mol of an electron donor. This solid product is preactivated by reacting it with both a dialkylaluminum compound and an α-olefin, and adding the reaction product of a trialkylaluminum compound and an electron donor. The polymer of the purpose is obtained by polymerizing an α-olefin such as ethylene or propylene in the presence of the catalyst above-produced.
