Abstract
PURPOSE: To produce PE having a uniform particle diameter and a high bulk density, by polymerizing ethylene in the presence of a catalyst consisting of a specified solid catalytic component and a specified organic Al compound.
CONSTITUTION: A catalyst is prepared by contacting (A) a solid catalytic component prepared by reacting a halogen-containing compound of Ti or V with a reaction product prepared by reacting (i) a reaction product between a hydropolysiloxane or an Si compound in which a hydroxyl group and organic groups are bonded to an Si atom and an organic Mg compound with (ii) 0.05W0.5mol, with respect to 1g atom Mg of component i, halogen-containing compound of Ti or V and further with (iii) an aluminum alkoxide and a halogen-containing Si compound of the formula, wherein X is Cl or Br, Y is H, an alkyl or an alkoxy and n is 1W4, with (B) an organic Al compound. Next, ethylene is polymerized at 30W200°C and normal W50kg/cm2 in the presence of the above catalyst.
