Abstract
PURPOSE: High-crystallinity α-olefin polymers are produced in high catalyst efficiency by using a catalyst prepared by combining a solid product of titanium resulting from the reaction of a titanium trichloride composition with a polysiloxane, an electron donor, and titanium tetrachloride and an organoaluminum compound.
CONSTITUTION: The polymerization of an α-olefin is conducted by using a catalyst prepared by combining (A) a solid product resulting from the reaction of (a) 100 g. of a solid titanium trichloride composition obtained by reducing titanium tetrachloride with a reducing metal such as aluminum, (b) about 1 W 2000 g. of a polysiloxane with a viscosity of 10 W 10000 at 25°C such as octamethyltrisiloxane, (c) about 1 W 2000 g. of an electron donor as diisoamyl ether and (d) about 5 W 1000 g. of titanium tetrachloride and (B) an organoaluminum compound. The order of the reaction of the titanium trichloride composition is preferably first with the polysiloxane and finally with titanium tetrachloride.
