| titleOfInvention | Olefin polymerization catalyst component |
| abstract | PURPOSE: To provide an olefin polymn. catalyst component with remarkably enhanced polymn. activity by plasma treating a TiCl 3 -based olefin polymn. catalyst component at a low temp. n CONSTITUTION: γ-TiCl 3 powder obtd. by reducing TiCl 4 with metallic Al or the like is charged into a discharge device previously replaced with N 2 . The system is then evacuated to remove N 2 , H 2 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-TiCl 3 powder. The treating time is above 1 sec and the treating temp. room temp.W200°C. The resulting polymn. catalyst component, the plasma treated TiCl 3 is used in polymn. of olefins in combination with an organo-metallic cpd., usually an org. Al cpd. such as Al(C 2 H 5 ) 3 or the cpd. and an electron donative cpd. The olefins may be 15 or less C olefins such as ethylene and propylene. n COPYRIGHT: (C)1979,JPO&Japio |
