Solid catalyst components for olefin polymerization and use thereof |
| abstract |
Abstract An effective catalyst carrier for use in the polymerization of olefins is provided. Said carrier comprises particles of silicon oxide or aluminum oxide satisfying the following characteristics (A) to (E): (A) An average particle diameter as measured by the sieving method is in the range of 20 to 150 µm. (B) A specific surface area as measured by the BET method is in the range of 150 to 600 m2/g. (C) The volume of pores ranging in pore radius from 18 to 1,000 Angstroms as measured by the mercury penetration method is in the range of 0.3 to 2.0 cm3/g. (D) An apparent specific gravity as measured according to JIS K6220-6.8 is not lower than 0.32. (E) After the particles classified in the range of between 53 µm and 75 µm by the sieving method have been subjected to an ultrasonic disintegration treatment at 40 KHz, 35W, for 20 minutes, the proportion of 50 µm or smaller particles, i.e., degree of ultrasonic disintegration, is not more than 30%. |
