Abstract

PURPOSE: To obtain solid TiCl3 suitable for use as stereoregular polymn. catalyst for α-olefins by reducing TiCl4 with an org. Al cpd. and bringing the resulting TiCl3 into contact with polysiloxanes or thioethers to modify or activate the TiCl3 at a relatively low temp.
CONSTITUTION: TiCl4 is dissolved in an inert diluent such as n-heptane, and an org. Al cpd. such as Al (C2H5)Cl2 is added to the soln. to carry out reduction at -30W20, esp. -10W10°C, thus preparing solid TiCl3. Polysiloxanes such as dimethyl polysiloxane or thioethers such as diethyl ether are then added to a soln. of the solid TiCl3 in a diluent such as n-heptane at around room temp. and heated to 50W150°C to carry out contact treatment. The resulting purple solid TiCl3 is separated. This solid TiCl3 catalyst is suitable for use as stereoregular polymn. catalyst esp. for ethylene, propylene, butene, etc.
