Abstract
PURPOSE: To obtain a polyolefin having improved particle properties, by bringing a catalyst comprising a solid substance containing Mg, Ti, etc. and an organometallic compound into contact with a gaseous α-olefin, and by polymerizing ethylene, etc, in the gas phase.
CONSTITUTION: (A) A catalyst comprising (a) a solid substance containing Mg, AND Ti and/or V, e.g. MgO-RX-TiCl (R is organic residue; X is halogen), (b) an organometallic compound is brought into contact with (B) a gaseous olefin, e.g. propylene, at 0W110°C for 1minW24hr, and then with (C) ethylene or its mixture with an α-olefin, e.g. ethylene, at 20W110°C and 2W60kg/cm2.G in the gas phase to (co)polymerize the ethylene or its mixture.
