Abstract

PURPOSE: To obtain a high-bulk density polyolefin, by prepolymerizing and then copolymerizing ethylene or an α-olefin with the aid of a specified catalyst system.
CONSTITUTION: Into a hydrocarbon solution containing a compound of formulaI, wherein R2 is (cyclo)alkyl or aryl, X2 is halogen and m is 1 or 2, and a compound of formula II, wherein R3 is R2, X3 is X2 and n is 1W3, is added an organic Al halide compound of formula III, wherein R1 is R2, X1 is X2 and 1≤1≤2. The mixture is reacted at 20W100°C to form a hydrocarbon-insoluble solid catalyst. This solid catalyst is combined with an organic Al compound of formula IV, wherein R4 is R2, X4 is X2 and p is 1W3, to obtain a catalyst system. Then, a (co)polymer is obtained by prepolymerizing 1W200g, per g solid catalyst constituting the catalyst system, of ethylene and/or a 3C or higher α- olefin at a pressure ≤50atm and a temperature of -40W150°C in the presence of the catalyst system and then (co)polymerizing ethylene or ethylene plus 3C or higher α-olefin at a pressure of atmospheric pressure to 100ptm and a temperature of 40W90°C.
