Abstract

PURPOSE: To prepare a propylene polymer having a very small amount of the non- crystalline portion, by polymerizing propylene, etc. in a homogeneous solution of catalyst and polymer prepared by treating titanium trichloride with an organoaluminum compound and prepolymerizing the monomer in the presence of the above product.
CONSTITUTION: Titanium trichloride is preliminarily made to contact with an organoaluminum compound in an inert organic solvent, e.g. heptane, etc., at 15W 60°C for 10minW5hr. Propylene or its mixture with the other α-olefins, (3W100g on the basis of 1g of titanium trichloride) is prepolymerized in the presence of the above catalyst and in the presence or absence of hydrogen, thereafter polymerized to give the desired polymer.
