Abstract
PURPOSE: To produce the titled polymer having a low fine-powder content and excellent fluidity, by polymerizing ethylene by use of a catalyst system consisting of a specified solid catalytic component, a specified organic Al compound and a specified electron-donating compound.
CONSTITUTION: A solid catalytic component (A) is obtained by reacting a solid component containing Mg, a halogen and a transition metal, a polyether compound, MW 400W10,000 (e.g., polyethylene glycol) or this compound and another electron-donating compound and/or an alkyl metal compound (e.g., triethylaluminum) at -20W140°C in an inert solvent and, if necessary, reacting the reacting mixture with an alkyl metal compound and/or an electron-donating compound. Then, ethylene or ethylene plus an α-olefin are (co)polymerized in the presence of a catalyst system consisting of component (A) and (B) an organic Al compound (e.g., triethylaluminum) and, if necessary, (C) an electron-donating compound (e.g., diethyl ether).
