Abstract
PURPOSE: The titled catalytic component which, in combination with a trialkylaluminum, shows a high ethylene polymerization activity, prepared by contacting a titanium halide with a carrier prepared by reacting a specified aluminosiloxy compound with a Grignard compound.
CONSTITUTION: A carrier is obtained by reacting 1mol of an aluminosiloxy compound of formulaI, wherein X1 is Cl, Br or I, which 0.1W10mol of a Grignard compound of formula II, wherein R1 is a 1W8C alkyl or X2 is halogen, at -50W 50°C for at least 5min. The solid catalytic component for ethylene polymerization is obtained by reacting the carrier with 1W100mol, per mol of said Grignard compound, of titanium halide at 20W200°C for 0.5W3hr in the presence or absence an inert solvent.
