Abstract
PURPOSE: To provide an olefin polymn. catalyst component with remarkably enhanced polymn. activity by plasma treating a TiCl3-based olefin polymn. catalyst component at a low temp.
CONSTITUTION: γ-TiCl3 powder obtd. by reducing TiCl4 with metallic Al or the like is charged into a discharge device previously replaced with N2. The system is then evacuated to remove N2, H2 or the like is introduced to a press. of 0.005W5 Torr, and plasma is produced at an output of 0.001W200 W to plasma treat the γ-TiCl3 powder. The treating time is above 1 sec and the treating temp. room temp.W200°C. The resulting polymn. catalyst component, the plasma treated TiCl3 is used in polymn. of olefins in combination with an organo-metallic cpd., usually an org. Al cpd. such as Al(C2H5)3 or the cpd. and an electron donative cpd. The olefins may be 15 or less C olefins such as ethylene and propylene.
